Upgrades to Exposure
Our trip to Robodojo earlier this month highlighted a few issues that needed to be resolved. Most of these problems were to do with the weapon assembly, which had way too much flex and caused us to lose the weapon in our first fight. Also, the 3D printed parts were PLA at the event (uh oh) so they needed to be re-printed in TPU with a slight redesign for some parts. The fork mounts needed a way to stop the forks rotating under the robot like they did in York, and the weapon spacing needed to be increased. After looking at different companies that could print what we needed, we decided that it would be easier (and probably more cost efficient) if we bought our own 3D printer and TPU filament. This also opens up a lot of opportunities for printed antweight and beetleweight chassises. The first step for improving the weapon was to move the weapon bulkheads outwards and extend them backwards to the piece that separates the drive motors from the rest of the robot. We changed the mounting
