Last week Mech Warfare Veteran Upgrayd came to Trossen Robotics to solder a batch of the new Mech Warfare transponder boards (You can see a video of him soldering the first batch of boards here.) In no time flat he had the boards built and ready to get sent out.
This year Mech Warfare is using a new custom built score keeping system – the MWScore System. Designed by Upgrayd, the MWScore System is completely open source (the MWScore Server, the transponder PCB files, and the transponder firmware are available for download here.)
The transponder interfaces with several force sensing resistors to register hits against the mech. These hit are reported to the MWScore Server via an Xbee connection, and displayed on the central server. The hit also triggers the new LED sub-board, that will flash 4-ultarbirght LEDs whenever a hit is registered. More details about the system are available at the MWScore site and this TRC forum post
Here’s a video of the scoring system in action.
