The Dice insert work cell is an assigned project through Eastern Washington university’s Mechanical Engineering program for Robotics and Automation. The primary objective was to design a work cell using a FANUC CRX articulated Robotic arm to pick and place as box, insert and dice to assemble together into one package. My partner for this project Duncan B was responsible for the insert design, mechatronics and programing of system. I was responsible for the design of the dice hopper, and pusher, selection of pneumatic components and motors used, assembly of work cell including on the fly modifications, and most of the documentation including a final report. The Dice hopper and extruder needed to take a bunch of 25 dice dumped into a hopper and push out a single die at the end for the robot to pick up. The solution I came up with was to use a funnel that would vibrate agitating and shifting the dice around so that a single die would drop down a shoot. An inductive sensor at the bottom would then detect of the dice was there. Further down is a secondary sensor that detected if the robot would need to pick the die up or not. If the die was not there and there was a die at the first sensor, the pneumatic would turn on pushing out the die. If both sensors did not detect a die, then the agitation motors would turn on until a die dropped down the shoot. Below is reference pictures of the hopper and video of the completed work cell.
