Friday, the FTC competition was amazing! FTC is FIRST Tech Challenge, and it’s where middle school and high school students build robots out of metal and some lego parts. The brain of the robot is an NXT, and they can program it in either RobotC, NXT-G, or LabView with the NXT toolbox.

The field is 12 feet by 12 feet, and this year’s challenge is called HotShot! The robots have to score wiffleballs into the zone in the middle, the nets above the zone, or the containers off to the side of the field. The wiffleballs are released onto the field when a holster tube is pushed. Yellow wiffleballs are better than white wiffleballs.

There’s a 30 second autonomous mode at the beginning of the game, followed by a teleoperated mode. The robots are controlled by a logitech controller that has joysticks and buttons (hahaha, what a lame description), which goes into software called the Field Controller Station. This software is on the laptop that the team supplies. The software then communicates via Bluetooth to the robot.

On the technical side of things, the Bluetooth works great if you have one robot. If you have 40 robots connected with Bluetooth, the air gets too cluttered. We ran into some problems the other day when robots started moving on their own and some teams would be disconnected if they switched from autonomous mode to teleoperated mode.

Problems or not, it was fun. Apparently it ran more smoothly than it did last year, so that was fantastic! Plus, one of the teams that I was helping gave me one of their team t-shirts! The music was great, and the event was streamed live from WCKN onto the internet!

There are 79 pictures that were taken live at the event up on team229robotics.com.

The FLL competition is today, Saturday December 5th. You can tune in to the live stream right here and subscribe to team229robotics.com’s RSS feed to have updated live blogging images as they come in!
