Hi ya all, So first, yes I realize this is not exactly a "PC mod" however I think some of you guys/gals here would find this interesting and could possibly give me and my team some advice, hence why I posted here. I posted in this section because it is one of the popular sections. =============== Overview: Me and my team is participating the FIRST Robotics 2010 competition. My team has been doing this for only four years (including this year), so we are not veteran (compared to some teams) and not rookies. So anyways, the basic game for this year is: A huge game of Soccer . You can see the basic idea about this years game here: If vid above doesn't work: http://www.youtube.com/watch?v=qbA33dX127E For more information about FIRST Robotics, rules (there's a TON of rules),etc: http://www.usfirst.org/roboticsprograms/frc/default.aspx?=966 Our team is from Chantilly, VA, USA (Westfield High School FCPS) and currently contains about 20 active members, so we aren't a really big team (some teams have like 90 people). ========== As of 1/23/2010: This is the front view of the bot. This is our prototype using the 80-20 10 series (~1x1x1") bars, connectors,etc using last years material. The final chassis will be made out of the same material but will be 2" shorter on length and width. The 20 lbs weights are at the front so we don't flip over the bump in the middle of the field. The electrical board. Everything is hooked up to a National Instrument's cRIO controller(very top item). Jagwire (the brown things) are used to control the speed of the motor via PWM. Gear boxes are behind the 120mm fan. The fan was put there because these motors (called CIM motors) get REALLY hot in ~1:30 (each round of the competition is 2:15). That fan moves ~200 CFM and is quite loud lol. Testing out the scoring mech . This will be a pivoting item with the pushing done by pneumatics instead of hands. ===================== So folks, Any ideas? Tips? Interested? Not sure if I am allowed to post this: My team needs to get some gears built (4-6) to increase our torque/speed. We have looked a bit locally (CNC) and the prices they ask are ridiculous imo (~$900 in one case). So if any of you can help out with this please post here or PM me.
