powerful servos
« on: March 24, 2011, 11:46:39 PM »
hi everybody,
I built the 50$ robot one year ago, after that I discovered Arduino, which is more simple, even if the 50$ bot was pretty easy to make(thanx for this great tutorial)...So I built different robots and machines, but always a bit limited because of the lack of power of the servos... So, my question is: does it exist powerful servos?, I mean servos able to make a 10 kilos robot move for example...and if such servos exist, is it expensive? and last question for people who know arduino...is it possible to control this kind of servos with arduino?
Thank you

Industrial servos exist, but they're not controlled like R/C servos, are extremely expensive and it's not a good idea to load a motor axle too much (sideways) - better use a free axle and use belts or sprocket chains to transfer the power.

If you just get DC motors with gear heads and a motor controller, you can control them with servo signals.
The Arduino could also control a home made H-bridge with direction and speed (PWM) signals.

A rather fast and fairly heavy robot with quite large wheels needs what? A lot of power?
Please remember...
