Though as the number of servos go up, keeping their wires neat and managing their control signals become a challenge. Once we start running more servos than we have fingers and toes, it’s worth ...

The fingers are controlled via a toothed belt system, with two beefy 11 kg servos responsible for flexing each individual finger joint. A third 25 kg servo flexes the finger as a whole.

The right feedback sensor is a key in motion systems that do what they are supposed to. Incremental disks are simple, having only one track shared by two sensors. The sensors are mounted so their ...

Both Leapp and Onyx steer themselves with servoactuators that pull on the parafoil. The servos use custom-wound dc motors married to planetary gearheads and capstans with machined-in grooves.
