Junior Design Competition Spring 2014

1. Junior Design Competition Spring 2014 • Pick and place robots • enable parts of various sizes and weights to be picked up and placed in new locations at high speeds. • are accurate and do not fatigue while performing repetitive movements that may be difficult for humans. • are versatile and can be reprogrammed and retooled to perform various tasks. https://www.youtube.com/watch?v=Em7C1SlqId8

2. The Spring 2014 Junior Design project requirements were to design, build, program, and demonstrate a computer-controlled pick and place robot that: • picks up, repositions, and releases 12.7 mm (0.5”) diameter steel spheres • sorts the spheres from one of nine base plate locations into one of two 14.3 mm (0.56”) diameter holes • provides motion in two rotary axes using two stepper motors controlled by an Arduino Uno R3 input/output board • uses a serially stacked axis configuration that is supported from one end only (rotary + linear) • lifts and lowers the steel spheres using a servo motor and a gripping mechanism • uses normally open micro switches on both positioning axes to identify the home position • automatically sorts spheres using code downloaded to the Arduino Uno R3 board.

3. Single elimination tournament, fastest team advances for each head-to-head competition • Each sphere must pass through the specified hole • Sorting sequence is {1B, 9A, 3B, 7A, 4A, 6B, 2A, 8B, 5A}
