Client needs a developer that can help in creating a record and repeat robotic arm. Also need help selecting an appropriate motor controller.
Client wants to build something similar to: https://www.youtube.com/watch?v=QVsdaPGUn1o
Except he wanst to use stepper motors with encoder attached to the back shaft.
Links to the stepper motors: http://www.phidgets.com/products.php?category=23&product_id=3330_0 and http://www.phidgets.com/products.php?category=23&product_id=3340_0
Links to the encoder: http://www.phidgets.com/products.php?product_id=3531
Client would like help on selecting a controller that would be able to accept the encoder feedback and control 5 stepper motors. Would like to use either an Arduino or raspberry pi.
The end product would be for the user to mount a welding gun onto the robot arm, and then to press a button that would start the recording; he could then weld for a little while, and press a button to stop the recording and then press a button to repeat the recorded movement.
