ROS, motor drivers, kinematics, and robotics communities
Components, kits, and an active community forum. One of the few places that carries obscure actuators and sensors with useful documentation alongside them.
The best structured learning path for ROS — courses go from zero to autonomous navigation without requiring a physical robot. Simulation-first approach that actually prepares you for hardware.
The standard framework for robotics — used in research labs, autonomous vehicles, and industrial systems. Steep learning curve, but unavoidable if you're building anything real.
Project showcase and tutorial platform with a high signal-to-noise ratio. Good for seeing how others have wired up sensors and actuators before you start.
Motor drivers, encoders, and chassis hardware that doesn't require reverse-engineering a datasheet to use. The go-to supplier when you need robotics hardware that works the first time.
A fully documented 6-wheel rover build based on the Curiosity design. The build guides are exceptional and the BOM is achievable without aerospace budgets.
