Modular chassis parts for small differential drive platforms, including base plates with integrated battery covers, snap‑in motor clips and ball castor assemblies. These components let a mobile platform carry power, mount gearmotors and run smoothly on floors while keeping wiring and sensors accessible.
Attributes vary by colour and finish, mounting style, material stiffness and caster design, which affect payload capacity, durability and ease of integration with wheels, encoders and sensor boards. Typical uses include classroom builds, prototype robots, sensor rigs and compact automation where quick assembly, reliable alignment and repeatable behaviour matter.
