More Gearboxes and Accessories
A 2 stage gearbox designed around the new friction brake. This gearbox is perfect for arms or turrets and many other situations where an axis needs to rotate.
Ideal for arms and other low revolution speed mechanisms
Easy integration with Friction Brake
Ability to get more reduction by mounting a VersaPlanetary Gearbox
Fixed or adjustable mounting options

Easy integration with your design
Same 1.875" bolt pattern as the VersaBlocks
The Friction Brake allows you to aid your PID controller in holding an arm, elevator or another subsystem in place or even completely hold your mechanism in place without any motor power!
Ratchet Plate (1/2" Hex)
The Ratchet Plate is designed to replace the traditional 1/2" hex wrench while also giving teams an easy and direct mounting experience with the integrated #10 hardware clearance holes.
These nifty little linear servos act like pneumatic air cylinders, but are powered by an electronic servo instead of compressed air! This means that not only do they provide reliable linear motion, but also have the added bonus of being able to extend to any position in its range of motion, not just full in or full out!
Available in 50, 100, and 140 mm stroke lengths
35:1, 63:1, and 150:1 gear ratios
Servo powered actuator does not take up a PDP slot
Mounts like a pneumatic air cylinder
