AVC from the vehicle’s perspective

Team 0x27 was the winner of this year’s AVC, the Autonomous Vehicle Contest put on by SparkFun Electronics. You’ll find video of the two runs from this entry (the third run did not finish). We love it that there’s an on-board camera recording both video and sound of the race from the vehicle’s point of view. They haven’t updated their team page yet but we’re sure they will once their done celebrating.

On the first run the team opted not to use obstacle avoidance, and here you can see it annihilating one of the barrels from the course (this is the second one it took out with hulk-like rage). These collisions didn’t keep it from finishing the circuit. On the second run it didn’t slam into anything. Because of the hoop-deduction (a bonus for threading the needle during the run) the official time came in at 2.08 seconds. Still, the unadjusted time of 32.08 seconds is a course record and beat the fastest finisher from the airborne group of compeititors. Nice.

Seriously, this video just cracks us up!

Cramming for Sparkfun’s Autonomous Vehicle Competition

[Paul Breed] participated in this year’s Autonomous Vehicles Contest put on by SparkFun Electronics. As with most projects, the deadline really snuck up on him and he ended up cramming a bunch of code development into the waning days before the competition. His experiences are shared in this recent blog post.

One big part of the hardware is a laser range finder used for wall following. This is explained well in the video after the break, but you can see the side-pointing blue box in the image above. [Paul] also spent a lot of time preparing for the checkpoint portion of the course where the vehicle would need to pass through a red hoop. He worked long and hard on an image processing setup to find and navigate those hoops before learning that they would be positioned at known locations and it would be much easier to use a path following technique to complete the challenge.

He had a few follies along the way. At one point during debugging the car — which was connected to his laptop via Ethernet — it got away from him. This ripped the NIC right out of the back of his computer. And on the day of the event he had some low battery issues that zapped his laser calibrations. But [Paul] rolled with the punches and ended having what sounds like a really exciting experience participating in the contest.
