Stop that Robot Jeep

The last thing we needed was a 5,000 lb full size Jeep going out of control at the 2014 Sparkfun AVC. One of our safety features was an on-by-default brake actuator.

The microcontroller deactivates it during a run but if hitting the e-stop, or shutting off the ignition, or arriving at the last waypoint re-activates the actuator and stops the Jeep. During the run I could still press the brake manually. Here's how we built it.

AVC: What About Data Bus?

Though Data Bus made it to the 2014 Sparkfun AVC, it had to sit out again this year. Time ran out to fix the Bus so I focused on the Jeep.

You can see Data Bus in the Sparkfun AVC recap video, sitting on the table near Troubled Child and also riding on top of the Jeep on our final run...

AVC: SHARC FSV, "Troubled Child"

Troubled Child, 1st Place in Doping and Crowd Favorite

Update: The SHARC FSV team Jeep, "Troubled Child," won Doping Class! And we were given the Crowd Favorite award! Wow! Yeehaw! Everyone on the team is super happy! Read on for details and video.

Congrats to all the other teams. I mean all of them. It's no small feat just to have something you can show up with. Anything beyond that is icing.
