(Figure 10). I used a pair of Finger Tech TinyESCs, a
Hobby King Nanotech 180 mAH 3S battery pack
(Figure 11), and an OrangeRX R400 receiver to complete
The tracks were fitted using standard Pololu
hardware except for the custom 6T front sprockets
(Figure 12); the wedge is attached using two 6-32 screws
The wedge is designed so that if it swings up or
down too far, it is stopped by the side panels. This is so
the bot doesn’t get high-sided on its own wedge. The
finished bot (Figure 14) drives well and is fast enough for
most Ant arenas.
I’ve named it “Swiss Wedge of Doom” and whilst I
doubt that it will win any events, it should be a crowd
pleaser. It will first compete at the Carolina Combat event
in July. SV
