Recent motor/gearbox's discussions

[Del]

Here are some interesting, recent discussions on some electric motor/gearbox's:

This one covers those inexpensive plastic motor/gearbox's that they sell at
Solorbotics and other places. I think these are also the ones used in the
Robosapien line of toys. From the results, it looks like a really bad idea to run
cheap motors at a higher-than-rated voltage.

This one gives a little more info on some inexpensive, but good quality
motor/gearbox/encoder's that are available all over the place.

Here are some places where these are available:

I would deffinitelly use the second motors, mainly for the quality and the built in encoders.

I found out that much smoother start-accelerate-to-top-speed-then-decelerate-untill-full-stop movement can be done using DC motors with encoders than with servos. I don't like servos anymore for driving the robot.
