 | | Gear Down Robot`

Has anyone created a geared down robot with a gear ratio of 8:40 x 8:40? My original creation is not 'good enough' to go in a straight line and after all the repsonds to my original message I still can not build one. I suck at the building part of (...) (24 years ago, 11-Mar-01, to lugnet.robotics)

Tricky , Tricky, here's the dilly, 8 to 24 tooth makes the fastest, but low output power, try to find the proper combo so your motors don't work to hard, add a worm gear to hold off the back spin, then try some more gears to get the speed you need, (...)

(...) Assuming the robot is being used self-powered (versus with AC adapter), would there be benefit in modifying the RCX to run off a single 9 volt versus all those AA's? That would save quite a bit of weight. :) Doing this wouldn't be "Lego pure" (...) (24 years ago, 13-Mar-01, to lugnet.robotics)

(...) This would cause the weight to go down for acceleration, but then when you turned off the motors, you would coast a shorter distance due to your less inertia. It would depend if you were building a robot for pure acceleration, or not. It would (...) (24 years ago, 13-Mar-01, to lugnet.robotics)

(...) In general terms, worm gears are less efficient than standard gears as they have more inherent friction - essentially, driving a worm gear is like pushing something up an inclined slope. How much this translates into a lego system I have no (...) (24 years ago, 13-Mar-01, to lugnet.robotics)

I think the best solution is to use NO gears. Without the additional friction of the gears and axles through beams, the motors are surprisingly powerful. I have had very good experience with direct drive robots. I suggest that you experiment with (...) (24 years ago, 13-Mar-01, to lugnet.robotics)
