Some readers may recall building a line-following robot during their school days ... steering motor salvaged from a power wheelchair. An Arduino Mega Pro Mini handles the logic, sending PWM ...

Sensors in the follower robot detect the force being applied to the object it is manipulating and communicate it to the leader robot, simulating touch and resistance and allowing the user to ...

Abstract: Robot-assisted guiding is gaining increased interest due to many applications involving moving in the noisy and low visibility environments. In such cases, haptic feedback is the most ...

This is done by using an ultrasonic sensor which provides information about the robot surroundings. All the processing is done on two Arduino microcontrollers communicating seamlessly.
