We also took the image of the Vex Claw and cut it out of 1/8€ acrylic. The front panel of the claw machine was placed into our laser cutter and the image was burned into the wood. The Exterior of the claw machine also incorporates many of the classes that are offered in Project Lead The Way. The top assembly is attached to the base using 8 removable bolts. Each component of the cabinet was assembled using a pocket jig and pocket screws. A removable platform was also constructed for the joystick and the drop button to rest on.
The base also has black acrylic walls to conceal any base wiring and keep the prizes within the prize area. There are two main sections to the cabinet, the base where the prizes are held and the top where the claw robotics main components are held. The cabinet was constructed from 3/4€ Birch plywood. We moved away from this idea because we did not have the materials at the time and getting them would be too expensive. This cabinet also featured a chute where the prizes can be received.
The playing area, top lid, and area where the claw machine systems are contained would be made from 3/4€inch birch ply wood.
The legs of the cabinet would be constructed from 1€x1€ angle iron. This is a sketch and a rendering of our original idea for the cabinet. This project took us around 3 months of in school time to complete. Parts from the claw game include many skills that we have learned during out time in PLTW including constructing structures with Vex parts, programming, rapid prototyping, CO2 laser cutting, and wiring. It’s not only fun and exciting, but it also incorporates each of the Project Lead The Way classes that we offer at Walker Career Center. Multipurpose Aluminum 90° Angles ( 1" x 1.The Vex Claw Game was chosen as our project for the first semester because we could really use it to promote engineering throughout the community.

Experiment with CMUCam and other sensors. Return to design proposal and consider the different sensing systems identified. Start making arms and dispensing mechanisms as well! Start acquiring materials for first prototype. Make sure each moving component and any rotating items have the necessary motor and perform general calculations for torque, speed, etc. List out specific motors needed to acquire based on our systems list.
