Product Description

This plastic chassis serves as the mechanical foundation for autonomous small robots and steerable model vehicles. The design features two independently driven rear wheels and a servo-steered front axle for intuitive maneuvering and cornering.

The chassis combines precisely drilled holes for standard gear motors with an adaptable servo mount, simplifying the integration of commercially available drive electronics. Its small dimensions also allow for compact project setups where space is limited. Anyone looking for a simple foundation for mobile robots or remote-controlled vehicles will find a proven basic design here.

The two driven wheels enable straight-line travel and turning in place, while the servo, via the articulated front axle, allows steering angles of up to about 30 degrees. The 67-mm wheelbase provides stable footing on level surfaces with a moderate turning radius. This makes the chassis suitable for indoor projects, on smooth floors or carpets, and for competitive robotics with size restrictions.

Operation requires two geared motors with M3 or M4 screws, a servo motor, a power supply for both motor types, and a microcontroller platform for control. Rough or steeply sloped surfaces are beyond the capabilities of this compact design; the wheels are designed for normal surfaces.

Safety Notice

The chassis is intended exclusively for building prototypes and for testing and development purposes; it is not intended for use in production environments or on machinery. When assembling and operating the system with electric drives, observe the safety requirements of the motors and power sources used. If you have questions regarding integration into more complex systems or the power supply, contact a qualified electrician before commissioning.
