An ultrasonic transducer converts electrical energy into ultrasonic sound waves above the range of human hearing using piezoelectric crystals. Systems use these transducers to generate sound waves above 18,000 Hz, which are reflected off objects, and the transducers convert the echo sound waves back into electrical signals to measure distance. Ultrasonic sensors work similarly to radar or sonar by sending sound waves and interpreting the echoes to calculate the time between the signal being sent and received in order to determine the distance to an object.
Robotics is a branch of science that deals with Mechanical, Electrical and Software fields. Robots are the machines that are used in our day-to-day to life to reduce men power and work accurately without any distortions. Robots can be classified into two different sections basing upon their skills as Automated and Manual. Obstacle detector is a Automated robot which itself recognizes the obstacle in its path and moves in free direction. Robot detects the obstacle by using two IR Sensors placed in front.
The IR sensors are placed on left and right side of the robot through which continuous Infrared radiation is emitted for detection of obstacles in the path. These IR Sensors are connected to a controlling element AT89c51 µc. When a obstacle is placed in the path of robot IR beam is reflected to the sensor from the obstacle. On detecting obstacle in the path sensor sends 0 volts to µc. This 0 voltage is detected by Microcontroller which avoids the obstacle by taking left or right turn. Similarly if the sensor sends +5v to Microcontroller, the Microcontroller assumes it as clear path and makes the robot to move in straight.
Two motors namely right motor and left motor are connected to Motor driver IC (L293D). L293D is interface with Microcontroller. Microcontroller sends logic 0 & logic 1 as per the programming to driver IC which makes motors to rotate in clockwise and anticlockwise direction. Wheels attached to the motors rotate accordingly with the motor shaft causing in the moment of the robot by wheels. In front portion of the robot a free wheel is attached to move the robot easily in any direction as per the requirement.
A 12Volts DC battery is attached to the circuit. As the microcontroller and sensors requires only 5v, set of resistors and capacitors are used to supply 5v DC to them. Power Management System is not maintained in the circuit as the battery can be removed after the usage of robot. So it does not cause any loss in the power of battery.
This type of robots has multiple applications in various fields. They can be used to know the strength of the opposite army in defense system. They can be used as floor and wall cleaners. They are used in automated GPS vehicles to calculate the moment of the vehicle overhead. These robots are easy to construct and cheaper in cost with long durability.

An ultrasonic sensor in a compact housing, with 20-450cm detection range.
Ultrasonic transducers are used in vehicles as parking assistance. The ultrasonic transducer sends out short ultrasonic impulses which are reflected by barriers. The echo signals are registered by the sensor and are evaluated by a central control unit.
This ultrasonic parking sensor from Bosch is very compact with its very few components meaning it is manufactured at low cost. The sensor is made with one electronic board, including a Bosch transceiver integrated circuit (IC) that drives the output of the Epcos/TDK transformer and evaluates the reflected signal. The transducer itself is made of a lead zirconate titanate (PZT) membrane and silver electrodes.

• As the name indicates, ultrasonic sensors measure distance by using ultrasonic
waves.
The sensor head emits an ultrasonic wave and receives the wave reflected back
from the target.
• Ultrasonic Sensors measure the distance to the target by measuring the time
between the emission and reception.
• Distance calculation
• The distance can be calculated with the following formula:
• Distance L = 1/2 × T × C
where L is the distance, T is the time between the emission and reception,
and C is the sonic speed.
(The value is multiplied by 1/2 because T is the time for go-and-return
distance.)
Features
• [Transparent object detectable]
Since ultrasonic waves can reflect off a glass or liquid surface and return to the sensor head, even
transparent targets can be detected.
• [Resistant to mist and dirt]
Detection is not affected by accumulation of dust or dirt.
• [Complex shaped objects detectable]
Presence detection is stable even for targets such as mesh trays or springs.
How Ultrasonic Sensors Work?
•Ultrasonic sound vibrates at a frequency above the range of human
hearing.
• Transducers are the microphones used to receive and send the
ultrasonic sound.
•Ultrasonic sensors, like many others, use a single transducer to send a
pulse and to receive the echo. The sensor determines the distance to
a target by measuring time lapses between the sending and receiving
of the ultrasonic pulse.
Ultrasonic Sensors
• Ultrasound can be used for measuring wind speed and direction
(anemometer), tank or channel fluid level, and speed through air or water.
• It generates sound waves in the ultrasonic range, above 18 kHz, by turning
electrical energy into sound, then upon receiving the echo turn the sound
waves into electrical energy which can be measured and displayed.
• The technology is limited by the shapes of surfaces and the density or
consistency of the material.
• Foam, in particular, can distort surface level readings.
• This technology, as well, can detect approaching objects and track
their positions.
• Ultrasonic transducers convert AC into ultrasound, as well as the reverse.
• Ultrasonic, typically refers to piezoelectric transducers or capacitive
transducers.
• Piezoelectric crystals change size and shape when a voltage is applied; AC
voltage makes them oscillate at the same frequency and produce ultrasonic
sound.
• Capacitive transducers use electrostatic fields between a conductive
diaphragm and a backing plate.
Selection of Sensors
The most common optical sensor options are photoelectric—diffuse, reflective, and through beam. Laser sensors and fiber-optic sensing units also fall under the optical sensor category. Photoelectric sensors are mostly presence sensors.
It is designed to measure the distance of any object by using an ultrasonic transducer. Ultrasonic means of distance measurement is a convenient method compared to traditional one using measurement scales.This kind of measurement is particularly applicable to inaccessible areas where traditional means cannot be implemented such as high temperature, pressure zones etc.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

3. Ultrasonic Sensor
An ultrasonic transducer is a device that converts energy into
ultrasound, or sound waves above the normal range of
human hearing.
Systems typically use a transducer which generates sound
waves in the ultrasonic range, above 18,000 hertz, by turning
electrical energy into sound, then upon receiving the echo
turn the sound waves into electrical energy which can be
measured and displayed.
4. Ultrasonic sensors (also known as transceivers when they
both send and receive) work on a principle similar to radar or
sonar which evaluate attributes of a target by interpreting the
echoes from radio or sound waves respectively. Ultrasonic
sensors generate high frequency sound waves and evaluate
the echo which is received back by the sensor. Sensors
calculate the time interval between sending the signal and
receiving the echo to determine the distance to an object.
5. Construction of Ultrasonic Sensor
Piezoelectric crystals are used for
this conversion process.
Piezoelectric crystals will
oscillate at high frequencies
when electric energy is applied to
it. The reverse is also true. These
piezoelectric crystals will
generate electrical signals on
receipt of ultrasound. These
sensors are capable of sending
ultrasound to an object and
receive the echo developed by
the object. The echo is converted
into electrical energy for onward
processing by the control circuit.

used for measuring: wind
speed and direction
,fullness of a tank and
speed through air or water.
For measuring speed or
direction a device uses
multiple detectors and
calculates the speed from
the relative distances to
particulates in the air or
water. To measure the
amount of liquid in a tank,
the sensor measures the
distance to the surface of
the fluid.
