Re: Take an exit with dignity

Re: Take an exit with dignity
Sorry I can't speak to that with much knowledge. I only know the 10000 ft. logic of the program. I can ask around and see what I get for an answer.

Re: Take an exit with dignity

Re: possible solution to the static problem
Sorry if this is a repeat I didn't have alot of time to post. We have begun using dryer sheets to wipe both the wheels and any lexan and/or plastic on the robot after every match. Thus far it has...

Re: Robotics in Private Schools
Another fantastic example is the Saint Paul's School in Concord, NH. They are team 1512. Their advisor Terry Wardrop would be the best person to talk to. He is very knowledgeable about the private...

Re: Treads, Tracks, Tank system Talk/Help
Your center of gravity has a very impact on this issue also. Assume you have a four cog setup (three similar to a six wheel drive setup and one tensioner) and your weight is either towards the front...

Re: Broken Belt
This is a little advice for tensioning sprocketed belts. When you tension a belt you only want the belt to be taught. It should be a straight line between belt sprockets when under no load and when...

Re: Belt Drive Pulleys
Two things. The Gates belting supplied in the kit is really good stuff. As long as it is tensioned its tough stuff. You can find it on McMaster Carr or look on their site for a local dealer. Local...

Re: Best Drivetrain
Right, exactly. You also don't necessarily need to limit them to 180 degrees of rotation (I understand the argument of why you would I'm playing devil's advocate). You could use a coaxial style setup...

Re: Best Drivetrain
That's not necessarily true. The reason 148 or 118 can't turn like a tank is because it has on central gearbox powering the entire drivetrain (not the rotation but the wheels). Coax crab can still be...
