The 4 Wheel Metal Chassis with Castor Wheel measures 20cm length, 10.5cm width, and 5cm height in metal construction, with 4-wheel drive DC geared motors plus an additional free-swiveling castor wheel, 13.5mm motor fitting holes, 21mm castor wheel fitting hole, and compatibility with DC motors, servos, Arduino, and robotics kits. This 4wd robot car chassis adds a fifth support point beyond the standard 4WD layout — the castor wheel is a non-driven, freely rotating wheel that provides additional stability and prevents the chassis from dragging or tipping, particularly useful when the chassis carries uneven weight distribution from batteries or electronics.
The chassis arduino car’s castor wheel mounting differs functionally from the four drive wheels — while the four primary wheels use 13.5mm motor fitting holes for direct DC geared motor attachment and provide propulsion and differential steering, the 21mm castor wheel fitting hole accepts a separate, larger swivel mechanism that rolls freely in any direction without requiring its own motor, reducing total motor count and wiring complexity compared to a 5-wheel-drive design.
One practical trade-off: this 4wd metal chassis kit’s added castor wheel increases overall footprint and part count compared to a pure 4-wheel chassis without castor support, and the castor mechanism itself requires periodic maintenance to prevent debris buildup affecting free rotation.
