That would make sense, using P=V*I, but for whatever reason FIRST defines servos likes this.
Quote:
COTS servos with a maximum power rating of 4W each at 6VDC
Per the Servo Industry,
Servo Max Power Rating = (Stall Torque) X (No Load Speed)
|
Following this steps from
this post and
this and from the spec sheet above.
Quote:
Free Speed 100 RPM @ 7.5 Volts
Stall Torque 6.5 in*lbs (approximately)
|
So Torque = 6.5inlbs=0.7344Nm (According to online converter)
100*.7344*0.1046=7.68Watts
So if all my math is right and I am converting everything proper, it does not seem that servo is under 4watts.
Uh .. The CMU cam still needs some tuning. It was more attracted to the trees and the green panels on the fence than the actual vision tetra.
