Hi people,
The robotic's boys use modified RC servos.They Convert a 90/180/360 degrees Servo to Continuous Operation. Digital hitec servos are programmable, they can have a 15kg kg*cm torque and metal gear.Inside heden there is a Faulhaber motor (Germany) and is a close loop servo system, RC servo is a open system.
Is a good idea to have a backup system with a RC servo and a Futaba radio, I'll try.
