Flex sensors
« on: December 17, 2008, 02:45:39 PM »
Hey can someone please post some information on flex sensors and using them with a basicx-24 micro controller. I am fairly new to robotics and am only 13 years old, so i would be glad for any help!

thanks

what kind of information are you looking for? And what do you need it for? Is there something in particular you are trying to do?

You might try these?

Not sure if its what you need. Like dragon said, what is it you're trying to accomplish?

For robotic arms etc. For example making a glove and a sleeve that are connected to a robotic arm. The arm will move accordingly to how the sleeve and the glove move.

The resistive bending sensors . . . basically hook them up to op-amps to amplify the voltage, then send the result to the ADC of your microcontroller. You can treat them just like potentiometers, but with only a small resistance range. Also, expect to have problems with hysteresis (google it).

the one with enough torque (subjective questions get subjective answers) :P
