-Team 188, Woburn Robotics.
-6 years of participation.
-2x CIM, 2x Drill, and 2x Fisher-Price.
-Wooden wheels with tread, four-wheel drive.
-No non-drive wheels.
-Chains run to front and back wheels for four-wheel drive.
-One-speed only.
-Tank-style steering.
-Sensors on the wheels to count revolutions and/or pointing down to detects the line or the HDPE.
-A good balance between speed and power; in a fairly high gear (speed of about 9ft/s), we could still push well because of six-motor drive, with a low-friction simplistic gearbox
-It draws way too much power, and by the end of a heated match, our robot can barely move. So many drive motors sometimes cause us to trip breakers. We made the mistake of using small chain rated for about 1000 pounds (25), instead of something stronger, we went through 13 of them because they stretched and snapped all the time. Our treads kept delaminating from the pushing matches we got into, so a better means of traction needs to be developed.
-Next year, we're going more complex, possibly with a new gearbox design conceived on the plane back from Houston that can do speed and power without most of the drawbacks we faced, and that's all I'll say. We're looking at tank treads also. Anything else is just speculation, stuff I don't know, or stuff I don't want everybody to know.
