# Robot actuator engineering guides

Choose a robot joint on more than peak torque. These guides separate manufacturer specifications, published research measurements, conditional engineering inference and unknown values. They describe proposed validation workflows, not tests we have performed on your hardware.

## Selection workflow

[How to select a robot actuator](/guides/robot-actuator-selection): define the mission, measure complete bus-to-output efficiency, validate installed thermal duty, test loaded output repeatability and identify a model on held-out trajectories.

## Version-scoped comparison

[CubeMars AK80-9 V3.0 KV100 versus original Xiaomi CyberGear](/comparisons/cubemars-ak80-9-vs-xiaomi-cybergear): what the documents establish, their revision conflicts, and why they do not prove an efficiency, thermal, precision or sim2real winner.

## Reducers are not integrated motors

Read family-level engineering notes for [Leaderdrive LCS](/actuators/leaderdrive-lcs), [LHD](/actuators/leaderdrive-lhd), [LHS](/actuators/leaderdrive-lhs), [Nidec WPG](/actuators/nidec-flexwave-wpg) and [Smart SRH](/actuators/nidec-smart-flexwave-srh). These distinguish input variants, sensor electronics and rating conditions without inventing missing motor specifications.
