Robotic Arm

Robotic Arm


Im looking for information involving a robotic arm.  I want to build a robotic arm that can rotate, raise&lower, and clamp and retract a claw.  I want to use a microcontroller to control it but i would appreciate any help on where to find information on building an arm, what parts i need, suppliers, etc.  If anyone knows some good websites about this topic or has some other resources i could use, i greatly appreciate any help that could be offered

RE: Robotic Arm


That is a pretty broad question to ask.  There are many manufacturers of components to put your own system together.  A couple I've used in the past are PHD, Tol-o-matic, and Gimatic.  They can be found at the following websites:


If you can give us an ideal of your application, it might be easier to give better direction.

RE: Robotic Arm

Thanks nornrich,

I didnt want to get into the nitty gritties but the application i want to do requires an arm to move an object from one location to another.  I want it to be able to rotate at the base,  i want the arm to raise and lower, and i want the claw to open and retract.  It will be lifting light objects and i want to make it approx 18 inches.  With regards to powering up i would prefer to use small servo motors and possible gears if not belt driven.  I hope this explains it better.  Any further help would be greatly appreciated!!

RE: Robotic Arm

    Are you sure you want to build this arm, it would be faster and probably a little cheaper to buy one off the shelf. See Robohand for grippers. Also www.animatics.com for servos, they have the Smartmotor. You may want to look at Tolomatic for stepper and servo controllers, drives, and motors. I would just buy an AIA actuator for speed and ease reasons. Hope this helps.
