This is our D2 (Dozer Two) 3 pound combat robot kit. These kit-bots have done extremely well in beetleweight combat, winning 3 northwest US events in 2015, and starting 2016 with another win, and then going on to sweep the beetleweight division in Robogames 2016!
The D2 kit is very robust, able to deal out damage with its wedge blade, and take massive impacts from bots with spinning weapons, and keep on running. This kit has been refined over the 2014 and 2015 competition seasons, learning from combat failures, and addressing those failures in each design iteration, resulting in our current very robust and competitive design.
Each kit-bot includes the following components:
- 2x CNC machined 6061-T6 billet aluminum side panels (D2-Side[B])
- 2x CNC machined 6061-T6 billet aluminum end panels (D2-End[A])
- 1x CNC machined 6061-T6 billet aluminum bottom panel (D2-Bottom[A])
- 1x CNC machined polycarbonate top panel (D2-Top[B])
