Robot reducers: planetary, strain-wave and cycloidal mechanisms
Compare three mechanisms and connect speed, torque and inertia with selection criteria beyond backlash.
Fundamentals · 5 minFrom motor speed control to FOC: current, torque and nested loops
Understand how speed control requests current and how FOC connects rotating coordinates, electrical angle and limits.
Fundamentals · 4 minRobot coordinate transforms: matrices, quaternions and TF
Use a numeric example to connect rotation, translation, inverse transforms, quaternions and ROS frames.
Fundamentals · 3 minRobot power design — diagnosing computer resets during motor startup
Relate motor load changes to voltage drops and locate faults across the battery, wiring, converter and computer.
Fundamentals · 5 minWhy sensor fusion fails — timing, frames and extrinsic calibration
Diagnose fusion failures through timestamps, coordinate frames, mounting geometry and covariance.
