Grant, John has a point on pricetag.

It doesnt need to be as expensive as mine though - a little bit of creativity and time is all it takes, maybe not quite that light, but close.

ALL Dales bots are worth a look.

Some nice engineering going on there, i like the damper flipper.. i pressume the motor just drives the arm back, compressing the air in the dampers, then the linkage is un latched releasing the power. pretty cool.

I have a question about torque...

Exactly how much is a oz-in..??

I read for example on Robot Marketplace that a Ampflow A28-400
motor has 3720 oz-in torque, but how many Nm is that..??

3 720 ounce inch = 26.268 972 82 newton meter, approximately
