Title: Sensor help
Post by: mymoon on August 07, 2014, 07:14:34 AM
Hi,

I need a sensor on a robotic arm that can detect humans, so that i can stop the arm when it hits a human. Any ideas that i can use? thanks in advance. ;)

you could turn any metal component into a capacitive sensor that would detect skin contact
torque sensors or current sensors would allow you to limit the force the robot applies and stop if it exceeds a certain value

Maybe use a long sharp metal pin on the arm. Then use a microphone to listen for screams of pain.
Otherwise it's hard to make sure you've hit a human, and not some other obstacle.
