Andrew Tridgell, Linus Penzlien, and myself are beginning to prepare for the autonomous ground vehicle competition at the Sparkfun 2014 AVC to be held at Boulder, CO on June 21st.
The picture above is that of our Traxxas E-Maxx 1/8 scale 4WD Crusher autonomous rover that is guided by a 3DR APM2.6 and employs a 3DR GPS/Compass module along with a 3DR 915MHz telemetry radio.
The video below will give you an idea of the performance of the Crusher. The rover reached a speed of around 7 m/s in the straightaways and negotiated three chicane waypoints while traversing a 1/8 mile test course. The Crusher can easily reach speeds of ~28 m/s, but I am shooting for good performance in the straightaways and chicanes at 10 m/s.
