MindSensors GlideWheel-M tests
MindSensors kindly sent me some GlideWheel-Ms to test. Here are my tests, and their results:
Speed test.
I wanted to see how fast the GlideWheel-M could go before it broke, or started to lose encoder counts. Also how well it handled different motors directly connected to it, as well as PWM. It's probably better explained in the video;
So, it handles most motors pretty well. PF-XL seems to be the best, with RC motor (obviously) doing worst. The GlideWheel-M can easily handle speed exceeding 1000 RPMs, though I don't really see a application that would be using that
Just some pics of the setup and motors.
Code:
task SpeedAdjust();
task main() { nxtDisplayCenteredTextLine(0, "Do you want"); nxtDisplayCenteredTextLine(1, "PID control?"); nxtDisplayCenteredTextLine(2, "This will give"); nxtDisplayCenteredTextLine(3, "speeds like the"); nxtDisplayCenteredTextLine(4, "MindStorms NXT"); nxtDisplayCenteredTextLine(5, "Servo Motor."); nxtDisplayCenteredTextLine(7, "No. Yes.");
So, there they are. I could've done better, but I was pressed for time (BrickWorld, cleaning up, etc). I also used these in my BrickWorld 2012 BOTS challenge robot, but that's another post.

Re: MindSensors GlideWheel-M tests
Nicely done!
"The GlideWheel-M can easily handle speed exceeding 1000 RPMs, though I don't really see a application that would be using that"
I can't seem to find where that motors top speed is. But when I was testing this, I supercharged a RC motor to about 1700 RPMs, and started to hear clicking noises withing the GlideWheel-M. So for "speeds exceeding 1000 RPMs" I would not suggest going over 1500 RPM. I would test the absolute limit, but don't have the money to replace broken parts, or to get enough RC motors for that speed.
