This project involves the creation of a robotic arm using the Lego Mindstorms NXT kit and using the Raspberry Pi with the BrickPi expansion board to run it. The BrickPi board uses the first 26 pins of the GPIO on the Raspberry Pi and can be powered with the supplied battery pack or a 5V power source. I've played around with Mindstorms kit for a while now and I wanted to test out the capabilities of BrickPi.
The arm is controlled via WiFi. I remotely connect into the Pi and I execute a python script to activate the arm. From there, I can use the directional keys to move the arm up, down, left, and right. Additionally, I use two other buttons to control the claw of the arm.
