Guides for robot builders.
Answers to the questions builders ask before they buy. Each guide compares the real options, names the alternatives with their sources and dates, and says where our products fit and where they do not.

Sync cameras and joint data to one clock
Why timestamps drift, three ways to deal with it, and how to measure the skew on your own rig.
Choose a smart actuator for a robot arm
Torque, backlash, encoder and bus for Dynamixel, Feetech, CubeMars, MyActuator and SmartServo G, and a closed-loop NEMA 17 you can script.
A cycloidal gearbox for a NEMA 17 stepper
Planetary, harmonic and cycloidal reducers for NEMA 17 compared, with list prices and backlash.
Competitor figures were read on the dates shown in each guide and may have changed. Checkmate products are shown before FCC authorization; see Legal.
