FPGA based synchronous multi-channel PWM generator for humanoid robot IJECEIAES
In this paper, synchronous multi-channel pulse width modulation (PWM) generator for driving servo motors of humanoid robot was proposed. In an application, the humanoid robot requires smooth and beautiful movement, therefore the PWM signal for each servo motor must be synchronized. Since microcontroller (slave) has no enough channels to generate synchronous PWMs for 32 servo motors, field programmable gate array (FPGA) was used as slave for the humanoid robot. The FPGA was controlled by microcontroller (master) using serial communication. Simulation results show the system can perform serial communication, synchronize, and convert data well. The system can also generate PWM simultaneously with accurate duty cycle and fix period of 20ms.

An automatic wave probe reference setting mechanism in a high speed towing tankeSAT Journals
Abstract The wave generation system in a High Speed Towing Tank (HSTT) generates regular and irregular waves to simulate wave condition during ship model testing. A wave probe is used to measure the height of waves generated by the wave generation system which is placed at the centre of the towing tank from the wave generation system. Generally the initial wave height reference (zero-point) at no wave condition is set manually and it is difficult to set reference accurately and the procedure is time consuming. The work aims at development of an automatic mechanism for adjustment of zero point in HSTT. The intended system enables remote monitoring and setting wave probe height reference with better accuracy minimizing human intervention. The prototype results confirmed the efficacy of the proposed mechanism. Keywords: Towing Tank, Wave probe, Wave generating system.

This paper focuses on the materials, working principle of a robotic vehicle which will be controlled with hand motion. The aim of this research is to enhance industrialization by creating a hand motion controlled robotic vehicle, since it uses hand motion it will be easier to use in automation and various industries. It is also very beneficial for people with disabilities since only hand motion is required. There were various materials that were used in the research. 2 microcontrollers, an accelerometer, RF modules, encoder, decoder, diode, motor driver IC, DC motor and batteries. The microcontrollers are small computers which can be programmed to be utilized in various different ways. The Accelerometer is a PCB or a sensor which detects speed. The RF modules are of two types which are transmitters and receivers and they are components which are used to send data and information wirelessly. The encoder and decoder are used to convert the binary to any n number of output terminals. The diode is used to send the electricity in one direction. The motor driver IC controls the DC motor from the information given by the microcontroller ICs and lastly a 9v Battery will be used to power the system. The arduino software will be used to program the IC so it can perform the required task. The gadget features a receiver circuit that is intended to be worn on top of the user's glove. The vehicle's circuit incorporates an RF receiver, an 8051 CPU, and a Driver IC to power the motors. This method is extremely useful for persons with impairments since it allows a robotic vehicle to drive itself using hand gestures. The person only needs to move his hand to move the car forward, backward, left, or right. As a result, the user is not required to push any buttons.

TRAFFIC SIGNAL CONTROL USING IR SENSORSKunal Kabra
The main objective of this project is to design an intelligent auto traffic signal control system.
Traffic congestion is one of the major issues to be considered. Generally Vehicular traffic
Intersects at the junctions of the road and are controlled by the traffic signals .Traffic signals
Need a good coordination and control to ensure the smooth and safe flow of the vehicular traffic.
During the rush hours, the traffic on the roads is at its peak. Also, there is a possibility for the
Emergency vehicles to stuck in the traffic jam. Therefore; there is a need for the dynamic control
of the traffic during rush hours. Hence I propose a smart traffic signal controller .The proposed
System tries to minimize the possibilities of traffic jams, caused by the traffic lights, to some
Extent by clearing the road with higher density of vehicles and also provides the clearance for the Emergency vehicle if any. The system is based on the AVR micro controller and IR sensors

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

features: 8K bytes of Flash, 256 bytes of RAM, 32 I/O lines, three 16-bit timer/counters, a six-vector two-level
interrupt architecture, a full-duplex serial port, on-chip oscillator, and clock circuitry.
B) IR sensor
The digital IR sensor consists of an IR transmitter, IR receiver, and an Op-Amp. Once powered, IR
LED continuously keeps emitting IR light. Hence the IR LED acts as transmitter and the photodiode acts as
receiver. As soon as the IR radiation is reflected back by a surface, it is absorbed by the receiver (photodiode).A
standard op-amp operating in open loop configuration (without any feedback) can be used as a comparator.
When the non-inverting input voltage (V1) is higher than the inverting input voltage (V2), the high gain of the
op-amp causes it to output the most positive voltage, i.e. the output of the op-amp will be high (1). When the no
invertinginput voltage (V1) drops below the inverting input voltage (V2), the op-amp outputs the most negative
voltage, i.e. the output of the op-amp will be low (0).

D) Voltage Regulator
Voltage regulator is used as voltage regulator in this line follower. This is applied to maintain constant
output voltage. Generally it consists of 3 terminals one input one output terminals and another one is ground
terminal. The output terminal is then connected to the power supply pin of the microcontroller. It looks like a
transistor but it is actually an integrated circuit with 3 legs. It can take a higher, crappy DC voltage and turn it
into a nice, smooth 5 volts DC.

IV. CONSIDERATION OF RULES FOR OBSTACLE AVOIDING
1) Path predetermining state
The system must be pre limited for going straight distance, turning left or right and returning back
straight to the starting point for no obstacles condition.
2) Obstacle is detected at the left
Stop for a while one or both sensors are detected. The system must turn to right and check if there is
any obstacle or not in this turning state. It must return to left and go straight at normal position.
3) Obstacle is detected at the right
The system must be stop for a whether one or both right sensor are detected. It must turn to left and
check if there is any obstacle or not in this turning state. And then it will return to right and go straight at normal
position.
V. V SOFTWARE IMPLEMENTATION
The focus of network applications under the IEEE 802.15.4 / ZigBee standard include the features of
low power consumption, needed for only two major modes (Tx/Rx or Sleep), high density of nodes per network,
low costs and simple implementation.
These features are enabled by the following characteristics
[1] 2.4GHz and 868/915 MHz dual PHY modes.
[2] This represents three license-free bands: 2.4-2.4835 GHz, 868-870 MHz and 902-928 MHz The number of channels
allotted to each frequency band is fixed at 16 channels in the 2.45 GHz band, 10 channels in the 915 MHz band, and 1 channel in
the 868 MHz band
[3] · Maximum data rates allowed for each of these frequency bands are fixed as 250 kbps @2.4 GHz, 40 kbps @ 915 MHz, and 20
kbps @868 MHz.

VI. CONCLUSION
A complete and reliable sensing system for obstacle detection can benefit a lot from the combined use
of sensors. Any one particular type of technology may have difficulties to meet all necessary requirements in
order to detect an obstacle in various lighting or weather condition. The path is store in memory by the
programmer, the motion of the vehicle is controlled by stepper motor and controlling of the machine is done by
micro- controller. Autonomous robotic vehicle guidance has been developed for industrial difficult. The
guidance systems consist of infra red sensor for obstacle detection, range determination and avoidance. It can
detect the obstacle within the range of 10 to 80 cm. These systems consist of infra red sensor and micro-
controller the sensor is mounted on the vehicle to acquire the information from its surrounding. The infra red
sensor is most suitable because of its low cost and ranging capability. The performance measurements
indicated that the visual basic was fast but also had a slightly larger jitter.
