ROBORAMA 2008B

The Dallas personal Robotics group held their semi-annual Roborama contest on Saturday November 22nd in Garland, TX. The DPRG had a table at the recent Austin makers Faire. Each spring and fall, they hold the Roborama contests for autonomous robots. The spring event has contests for outdoor self-navigating robots. The 2008b contests were developed to test the abilities of indoor robots. typically held at the science Place, this year they elected to have the contests at the DPRG storage facility in Garland.

There were a broad variety of robots represented: lots of built-from-scratch projects, some lego-bots, and a few off-the-shelf models. Computing power ranged from nothing up to an on-board PC with WiFi. The Polulu 3pi‘s were heavily represented. The contractors themselves were anything from high school students to veteran club members.

Winners had their choice of prizes in purchase of placement in each contest (first place got to pick first, etc). Prizes included a STM32circle, a pair of servos, or gift certificates to a local electronics store. other entrants got a mini-cylon LED display to make their robot a little much more menacing. You can view full results here.

The simplest event was the Quick-trip contest. This competition had the robots relocation from the starting area straight to a second area, and back again. The area is enclosed by walls and marked off with black tape, and the robot should completely cross the tape to be considered in an area. While it sounds very simple, not all robots were able to complete the course. The winners were identified by who successfully finished the course in the least time. This years winner of the Quick-trip contest was a lego-bot named Gort built by student Nathan Harlan.

The second event is a little much more complex, called T-Time. this one has three areas, and tests the accuracy of turning. There are 3 areas, the robot starts in one, should visit the other two and return to the start area.  The course is a ‘T’ shape, so the robot should make a couple of turns. It was won by David Martineau with BoxyRoxy Mk IV.

The third event was a line-following competition. Robots should follow a white stripe on black background, with lots of sharp curves.  The course itself was only about a yard square, so smaller bots fit much more easily. This year the line following was all about the Polulu 3pi’s. At least 4 entered, and all of them used the unmodified hardware: the only difference was the programming. One contestant used a genetic algorithm to develop a neural-net. another contestant programmed his on the day of the contest. The winner was PI R Squared, owned by Steve Rainwater.

The next Roborama will be sometime in the spring of 2009. DPRG holds montly club meetings. They also have the Robot contractors night Out, which is a chance for roboticists to meet at the Garland storage facility and work on thier robots. It is open to anyone, not just club members.
