In today’s world there are many disabled persons who find it difficult to perform movements or perform daily activities. This types of persons are mainly dependent on others for their assistance. But they can become self-independent and perform some daily activities on their own with the help of assistive devices. The most widely used assistive devices are Wheelchairs. Wheelchairs is basically a chair fitted with wheels, which can help people move around who cannot walk because of illness, disability or injury. But there are many disabled people with weak limbs and joints who cannot move the wheelchair. Thus, smart wheelchair can benefit a lot to them and everyone in society. Smart wheelchairs are electric powered wheelchairs with many extra components such as a computer and sensors which help the user or guardian accompanying wheelchair to handle it easily and efficiently. The recent development in the field of Artificial Intelligence, sensor technologies and robotics help the growth of wheelchairs with new features. This paper is to review the current state of art of smart wheelchairs and discuss the future research in this field.

MOVING VEHICLE FOR A PERSON WITHOUT HAND PROJECT REPORTVanchhitrawat
This document discusses the need for a foot-operated vehicle for people without hands. It notes that over 27 million people in India, about 2.21% of the population, have some form of disability. Of those, 5.43 million have disabilities affecting their movement. Currently, people with disabilities in their upper or lower extremities have difficulties traveling long distances. While wheelchairs and other devices help with mobility, they are not suitable for outdoor transportation over 15-20 km. The project aims to design a foot-operated vehicle using a rack and pinion system to convert rotary foot motion into linear vehicle motion. This would provide independent long-distance transportation to people without the use of their hands.

Intelligent Transportation Systems editor Alberto Broggi introduces an article on sensor-based pedestrian protection in vehicles. The article reviews current approaches using video, radar, and laser sensors to detect pedestrians. Video-based methods use computer vision techniques but have difficulties with moving cameras and backgrounds. Radar and laser rangefinders can directly measure distances but require further development. The article describes three existing systems that combine stereo vision with other sensors and algorithms. Significant challenges remain to reduce false alarms while maintaining a high detection rate of pedestrians. Future systems may need to understand traffic scenarios to better assess risk.

This document discusses how South African youth have lost faith in the education system. It notes that 80% of schools are dysfunctional and unable to impart necessary skills. Youth feel disrespected and talked down to in school. They want to learn practical life skills but feel the education system fails to prepare them for the real world or teach them how to think. While hungry to learn, youth feel the linear teaching style does not connect with them. They desire skills like business, health, finance, but do not feel the education system provides these.
Este trabajo discute la secuencia de desarrollo histórico prehispánico en el Norte Semiárido de Chile a partir del estudio de las dinámicas espaciales y temporales de las ocupaciones humanas en la cuenca hidrográfica del río Limarí. A partir del estudio de asentamientos, materiales depositados en colecciones y arte rupestre se observa una secuencia de transformaciones y desarrollo desde el Arcaico Temprano hasta el período Incaico que diverge de lo tradicionalmente planteado para la región, reconociéndose ritmos de cambios sociales diferenciales dentro de la misma zona, especialmente en relación con la tradicional asociación entre incorporación de cerámica y la constitución de un modo de vida agrícola. La incorporación del arte rupestre permite articular sus características espaciales y representacionales con procesos más amplios, discutiéndose las relaciones establecidas entre dinámi- cas y cambios sociales con los flujos de información que producen las representaciones rupestres y sus respectivas audiencias.
El trabajo aborda las epistemes decoloniales como prácticas antagónicas al estado de relaciones (inter)culturales impuestos por la colonialidad. A partir de un análisis semiótico aplicado a dos obras del pensamiento mapuche, se propone la dimensión epistémico decolonial como basal en su organización de sentidos, comprendiendo que son sistemas de conocimientos en oposición a las formas de dominación que desde el mundo moderno-colonial se han ejercido en desmedro del pueblo mapuche. Se concluye proponiendo que este tipo de epistemes contribuyen a re-escribir la interculturalidad, construyendo, así, un nuevo marco de convivencia humana.

Height and depth gauge linear metrology.pdfq30122000
Height gauges may also be used to measure the height of an object by using the underside of the scriber as the datum. The datum may be permanently fixed or the height gauge may have provision to adjust the scale, this is done by sliding the scale vertically along the body of the height gauge by turning a fine feed screw at the top of the gauge; then with the scriber set to the same level as the base, the scale can be matched to it. This adjustment allows different scribers or probes to be used, as well as adjusting for any errors in a damaged or resharpened probe.

ABSTRACT— A smart multipurpose human assistance robotic dog is designed to guide the visually impaired and
elderly people to some predefined destination avoiding obstacles and traffic. It is also designed to act as an advanced
multipurpose human assistance and service robot that is able recognize the words spoken by the user, talk to them and
take action according to the spoken voice command. Voice commands are recognized by an android Smartphone and
the information is transferred to the main MCU using a Bluetooth serial port that runs Bluetooth SPP protocol stack.
The robotic dog has the ability to follow a human when commanded with voice. Touch sensitive e-skin senses
human finger touch and helps answering complex user requests such as time, date and weather conditions such as light
and temperature. The same can be asked using voice also. It even allows the user to set wake up alarm. A built in audio
playback system can play music tracks in MP3 format. One of the music tracks is kept as the alarm tone. It also plays
the role of a regular watchdog during night and barks like any normal dog if it finds any abnormal activity. During the
day time it can charge itself by moving around within a given region in order to find the maximum sun light,
intelligently avoiding the shaded areas, thereby freeing the user completely from maintenance issues such as battery
charging.
KEYWORDS— Human walking intention, Voice recognition, speaking robot, digital MEMS, Bluetooth serial port,

I. INTRODUCTION
Guide dogs are assistance dogs trained to lead elderly or visually impaired people around obstacles. These
dogs need to be trained by some special training institute and maintained healthy in order to help people. Being a
service dog, they also have a maximum lifetime around 8 to 10 years. These dogs help them in one another way.
Elderly people are often left alone and have least amount of interaction with other people. Although a guide dog relieve
them from such a situation, they are dumb and lag intelligence of a human companion.
For many visually impaired people, a cane or a stick is a close friend helping them to detect and avoid
obstacles in the walking paths. During walking with the cane, they sense and guess directions and locations by hearing
sounds surrounding, sniffing smells in the air, feeling touches on skin, counting footsteps they walk, and memorizing
events in time and spaces. However, it is difficult for them to do this all the time when surrounding environment could
suddenly change, or when they get lost memory of locations. Voice Recognition Robotic Dog Guides Visually

II. RELATED WORK
AS many countries step into the aging society rapidly, more and more elders suffer from deficits of motor
function or disability of the limbs, which are usually caused by neurological problems or lack of muscle strength. In
addition, the growing elderly population causes the shortage of people for nursing care. Therefore, there is a great need
to develop rehabilitation robots that can partially replace the nurses and the therapists. Currently, plentiful studies on

rehabilitation robots can be found, including the applications for the upper limb [1]–[5], for the lower limb [6]–[9], and
for the assisting or training of the whole body [10]–[13]. In daily life, the walking is one of the most important human
activities. To improve the walking ability of the elderly, the walker-type rehabilitation robot has become a popular
research topic over the last decade. There have been many intelligent walker-type robots comprising active or passive
wheels and supporting frame. A novel assistive robotic walker called “JAIST active robotic walker (JARoW)” to
provide potential users with sufficient ambulatory capability in an efficient, cost effective way was presented in [14].
The Hitomi system to help the blind in outdoor environment was proposed in [15].Apowerassisted walker for physical
support during walking was developed in [16]. The Care-O-bot and Nursebot are developed as personal service robots
for elderly and disables [17], [18]. The personal aid for mobility and monitoring (PAMM) system to provide mobility
assistance and user health status monitoring was proposed in [19]. A new intelligent walker based on passive robotics
to assist the elderly, handicapped people, and the blind was proposed in [20]. There are still many deficiencies in the
present walker systems. First, many walkers are designed for the indoor environment. Second, most of them are big in
size and/or heavy in weight. An indoor robot is often restricted within limited places. Big size makes it impossible to be
used in narrow space and heavy weight restricts the man euverability. Many elders and patients are not so weak that
they have to be nursed carefully. Nevertheless, sufficient support, such as a cane or stick, is necessary to help them take
a walk outside, which enables them to realize high-quality lives or accelerate the rehabilitation. In these cases, an
intelligent cane system may be more useful than walkers due to its flexibility and handiness.
In [19], a Smart- Cane system is also proposed, which has a relative smaller size and nonholonomic constraint
in kinematics. The nonholonomic constraint is useful for moving along a path stably, but reduces the maneuverability
of the system. In [21] and [22], the “GuideCane” and a robotic cane “Roji” are proposed for blind or visually impaired
pedestrians to navigate safely and quickly through obstacles and other hazards. In the living environment, including the
narrow space, the cane system is expected to be movable in omni directions. Thus, omni directional mobile platform is
needed in the robot design. This kind of platform has been considered in some applications [23], [24], whereas their
designs are special and not commercially available. Particularly, they are proposed for walker systems but cane
systems, which are much smaller in size. Recently, commercial omniwheels are applied in the area of walker systems
[25]. The problem that slender rollers of omniwheels have limited load capacities is partly solved by the modern
technology. In addition, a small omnidirectional platform can be constructed by this kind of wheels. In our previous
study, an intelligent cane system was designed based on a commercially available three-wheeled omnidirectional
platform [26]. We also investigated the fall detection and fall-prevention function of the cane robot systems in [27].
The recognition of user’s walking intention plays an important role in the study of the walker-type rehabilitation robots.
From the viewpoint of the control system of robot, the walking intention provides a real-time reference trajectory for
the robot motion controller. Therefore, the more accurately the walking intention is inferred, the more satisfactory the
control performance of the robot may be obtained.
A manufacturing system that is controlled based on the human intention/desire was proposed in [28]. The
dance partner robot, which estimates the intention of human dancer, was proposed in [29] and [30]. When we pay
attention to the walker-type walking support system, similar researches can be found in [31] and [32]. In the study of
motion–intention-recognizing approaches, the EMG-based methods are widely applied [2], [3]. However, the EMG
signals are easily influenced by the location of electrodes, the thickness of fattiness, the body temperature, and the
perspiration. Meanwhile, the information of the EMG signals is so large that a complicated pre-processing procedure is
required before using them as the control input. In this paper, we improved our former intelligent cane system and
studied its motion control problems in several situations based on estimating human walking intention. The human
walking behavior is described by switching walking modes. To model the human walking intention, an important
concept called “intentional direction” (ITD) is proposed, as well as its dynamic model during human walking. Without
knowing the ITD accurately, it is not an easy task to design a motion controller of the cane robot for an elderly or a
handicapped user. Normally, these people cannot walk along their ITD clearly and smoothly due to their weak or
handicapped lower limbs. For instance, even an elderly intends to walk straightforwardly, he/she might finally walk
along a zigzag trajectory because of stumbling. Therefore, the interactive forces measured by the cane robot consist of
plentiful user’s unintentional walking information, which is part of the observation noise in the dynamic model of ITD.
Comparing with a young healthy subject, apparently this observation noise of ITD is much bigger. Thus, it is necessary

to pick up the ITD as accurately as possible from the noisy measurement. After that we may design a robot motion
controller based on the ITD to aid the user’s walking in accordance with his actual walking intention. Some filtering
technologies are used to online estimate the ITD, based on which a new force control scheme called “intention-based
admittance control (IBAC)” is proposed to provide a natural and intuitive interface for elderly users.
III. EXISTING SYSTEM
In existing method they used cane robot for aiding the elderly and handicapped peoples walking. For many
visually impaired people, a cane or a stick is a close friend helping them to detect and avoid obstacles in the walking
paths. During walking with the cane, they sense and guess directions and locations by hearing sounds surrounding,
sniffing smells in the air, feeling touches on skin, counting footsteps they walk, and memorizing events in time and
spaces. However, it is difficult for them to do this all the time when surrounding environment could suddenly change,
or when they get lost memory of locations. Voice recognition method is not used in existing method. Cane robot is not
user friendly.
An intelligent cane robot is designed for aiding the elderly and handicapped people’s walking. The robot
consists of a stick, a group of sensors, and a unidirectional basis driven by three Swedish wheels. Recognizing the
user’s walking intention plays an important role in the motion control of our cane robot. To quantitatively describe the
user’s walking intention, a concept called “intentional direction (ITD)” is proposed. Both the state model and the
observation model of ITD are obtained by enumerating the possible walking modes and analyzing the relationship
between the human–robot interaction force and the walking intention. From these two models, the user’s walking
intention can be online inferred using the Kaman filtering technique. Based on the estimated intention, a new
admittance motion control scheme is proposed for the cane robot. Walking experiments aided by the cane robot on a
flat ground and slope are carried out to validate the proposed control approach. The experimental results show that the
user feels more natural and comfortable when our intention-based admittance control is applied.
Fig 1 (a) Walking on the flat ground. (b) Walking on the slope.
The direction to which a person intends to move is referred to as the ITD. The ITD can be evaluated by the
angle between the forward direction (along with the axis yr) and the ITD itself. Obviously, the ITD is a time-dependent
value and is denoted by ρ(n) in the rest of the paper. Furthermore, the quantity of this intention is characterized by the
measured resultant force Fρ (n) along the ITD. Note that discrete time scale n is assumed for the requirement of
filtering technology.
In this existing method, a new omni directional-type cane robot was developed for the elderly and
handicapped. Motion control of this robot was studied based on online estimating human walking intention. The main
contribution of this study has been to present dynamic models and online inference algorithm for the human walking
intention, which is significant to lead the user’s walking in a natural and comfortable way. An IBAC scheme was also

proposed and used to drive the cane robot. Experiments were performed on the flat ground and slope. The effectiveness
of the proposed algorithm was confirmed through experiments. It should be pointed out that the interface between the
human and the robot is the multiaxis force sensor, which is expensive and fragile. To lower the cost and improve the
system reliability, in the future, we would like to construct a low-cost sensing system comprising cheaper force sensors
(e.g., force sensing resistors) and range finding sensors for the cane robot. By utilizing some sensor fusion approaches,
the state of user can then be reliably recognized and provided to the motion controller.
IV. PROPOSED SYSTEM

The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly
proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature sensors
calibrated in ° Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain
convenient Centigrade scaling. The LM35 does not require any external calibration or trimming to provide typical
accuracies of ±1⁄4°C at room temperature and ±3⁄4°C over a full −55 to +150°C temperature range. Light dependent
resistor is used to find the sun light and tells day or night.

VI. CONCLUSION
In this project a multipurpose assistance robot is designed from the existing technique which effectively helps
visually impaired people with zero maintence. Detection of obstacles with the help of sonar sensors gives more
accuracy than any other sensors. In this project we have used voice recognition method which helps to recognize
human voice. This recognition method is achieved by android mobile phone
Additionally, robotic dog has the ability to follow a human when commanded with voice. It also plays the role
of a regular watchdog during night and barks like any normal dog if it finds any abnormal activity. During the day time
it can charge itself by moving around within a given region in order to find the maximum sun light, intelligently
avoiding the shaded areas, thereby freeing the user completely from maintenance issues such as battery charging. It has a
head; eyes and a tail like a real dog which it uses to perform special gestures during human-robot interaction. Thus the
results show that the method is also effective in reducing power and maintence.The proposed scheme has been validated
by simulation using voice recognition module and implanted to evaluate its performance in terms of receiving voice and
recovered.
It is decided to implement the design for the robotic devices to achieve artificial intelligence which is
independent and thinking capability of different operations and assist human kinds.
