The 4WD Aluminum Robot Car Chassis Frame is a 1.5mm aluminum alloy base plate measuring 250mm × 150mm, with integrated motor brackets featuring precision-drilled mounting holes, anodized corrosion-resistant surface finish, and blue protective film over a silver aluminum base. This aluminum robot chassis solves a common DIY fabrication pain point — rather than builders needing to measure, mark, and drill custom motor mounting holes by hand, the precision-drilled bracket holes are pre-positioned to standard BO motor mounting spacing, allowing direct bolt-on assembly without any manual drilling or measurement work.
The 4wd chassis frame’s 250×150mm rectangular footprint gives a notably wider wheelbase than smaller chassis options in the same weight class — this wider stance improves lateral stability during turns and reduces the tendency to tip on uneven surfaces compared to narrower chassis designs, which matters particularly for line-following and obstacle-avoidance robots that change direction frequently. This metal chassis for robot’s anodized surface finish is not simply a painted coating — anodizing is an electrochemical process that grows a genuine aluminum oxide layer integral to the metal surface itself, making it significantly more durable and scratch-resistant than a sprayed or painted finish would be.
One practical trade-off: this robot car base plate’s fixed 250×150mm dimensions and pre-positioned bracket holes mean builders working with non-standard BO motor variants or custom motor spacing will need to verify compatibility before ordering, since the precision holes are not adjustable or re-positionable. Available from StemVolt, offering quality robotics parts.
