Title: microcontroller for robotic arm
Post by: dmehling on May 22, 2007, 02:44:52 PM

I am trying to determine the best kind of microcontroller system for my proposed robotic arm.  Technically, it is not fully robotic since in my present application I intend for it to be controlled by external input through a switch.  It is a very simple design with only 2 degrees of freedom.  Would the Cerebellum microcontroller be suitable for this design or is it more complicated than I would need.

I am currently designing a robot arm and its controller using a PIC16F628A.

All that the microcontroller does, is accept bytes from my computer via a serial interface, and outputs PWM signals to the servos based on the bytes received. The actual positioning of the arm is calculated by the computer. Therefore a powerful processor isnt needed to do the inverse kinematics etc.

Your given specs can be handled by almost every microcontroller out there. Just find what you think would be simple and easy to learn and you should be fine :)
