##### To construct high acceleration robot
« on: September 23, 2011, 06:02:16 AM »
Hi guys, I need to construct a high acceleration robot for a competition where the robot must travel a path which is flat for a major portion and has some bumps (speed breakers) and a ramp (slope of 40 degrees). The robot dimensions are 250mm*250mm*250mm(l*b*h). So, I need that the robot should go fast and should have enough torque to overcome the bumps and ramp. Please anyone suggest which kind of motors should I use and how to construct the bot

Until you give us some more details, the best suggestion I have for you is to use some model rocket motors =).

More seriously, how much is "go fast" and "enough torque"? You don't give us any information on the bumps, or the flat path.

Aah.,    The arena has bumps of 5cm diameter and a ramp of 40degrees inclination. You can view it here-
There are zigzag obstacles, a ramp and the bumps at the top right corner. If you can spend a little more time you can see the details of the event over here - http://www.techfest.org/home/event/magneto. Select 'Arena' to view details about it.
Now the thing is that who finishes the track in the least time wins  Simple. . . But to finish it quick we must have 'SPEED' and to overcome those obstacles we must have 'TORQUE'. . Initially i thought of using stepper motors and later found out its a very bad idea  So, I can't figure it out which kind of motor is best . . but please don't suggest me some rocket stuff ..  later none can see the robot once it starts
