Robot Arm help!
« on: February 02, 2012, 03:12:46 PM »
Hey guys, I've built this robot arm from a kit and I find it is really slow. Right now it is running on DC accutators with a 6.0 volt energy supply. Is there a way to replace the accutators with something.. faster? Plus, I found this really awesome gripper with an approximate 9 cm span. The only problem is it is connected to a Vex servo motor, is there a way I can modify the servo head piece into a DC motor head. Thanks!

Hi there, we also building a robot grip which will be grasping the objects, meanwhile it also checks whether it is slipping or not...if it is slipping more force will be applied so which sensor should i use and which micro controller....please help me out with this

Only computer vision comes to head.

What sort of object robot will be handling? Are they very different objects, ranging from ice blocks which may slip and are very fragile to some iron pipes which can take a lot of pressure and are very heavy? If all handled object have similar properties, best thing to do is to have grip strength preset in code rather than use dynamic system.
