While working on building a friend's robot, I got the urge to build my own. Intern Bot came about to see how much functionality I could get out of cardboard, hot glue and Arduino. I've included a Raspberry Pi to add even more.
The arms use metal gear micro servo motors to move each joint. Mounts for the servo and mounting plates for the servo horns were 3D printed. On the underside of each servo, a paper fastener is used to secure the hinge. Each arm is connected to a geared dc motor.
Next step is to setup the Raspberry Pi. The Pi will be the brain of the Intern. I've added a camera module and with it I want to see what I can with Python and OpenCV. I will also add a microphone to play with adding voice commands.
