That's kind of the opposite of what you want, but it may (...) (21 years ago, 15-Feb-04, to lugnet.robotics.rcx)

| | | | (...) Now that is conveinient! ;) (...) I am messing around with this idea hoping to get the gear ratio I want (2:5). I currently have 16t on the motors driving 40t on the drive axle. I haven't come up with a good way to incorporate the differential (...) (21 years ago, 15-Feb-04, to lugnet.robotics.rcx)

| | | | (...) Okay I've done it. I have the drive train all figured out with the exact gearing I wanted. Now the question to answer before I totally tear down and rebuild a complete robot is; will adding an additional 2 motors to help in forward and reverse (...)

| | | | | (...) It's been my experience that a robot with 6 motors will push harder than a robot with 4 motors. (...) If you're concerned about spending money on batteries, your best bet is to go with a 2 motor robot. If you want to build a really strong sumo (...) (21 years ago, 16-Feb-04, to lugnet.robotics.rcx)

| | | | | | (...) My main concern isn't spending money on batteries, that's just something that popped in my head when I was listing our questions I had about the 6 motor solution. My main concern is getting half-way through the tear-down/rebuild process only (...) (21 years ago, 16-Feb-04, to lugnet.robotics.rcx)

| | | | (...) Great. My method was to combine the motor outputs down to two axles (left & right) and then do the gearing down/up. I also played with running the "boost" motors at a different gear ratio than the other four, but wasn't sure it would help (...) (21 years ago, 16-Feb-04, to lugnet.robotics.rcx)

| | | | (...) Thanks Brian, I doubt I will attempt your suggested test of driving into a wall (this scares me very much!) but I hear what you are saying. Based on Steve's reply, I have decided that 6 motors pushing is better than 4. Since I have already (...) (21 years ago, 16-Feb-04, to lugnet.robotics.rcx)

| | | | (...) Actually, I think what he's suggesting is a pretty good idea. I usually test most of my sumo robots this way. Place the robot next to a wall. If you don't want to damage a wall with a big, powerful robot, :) use a book held against the floor (...) (21 years ago, 16-Feb-04, to lugnet.robotics.rcx)
