Common chassis types and quick specs

Most cheap robot chassis fall into these categories. Use the table below to compare typical specs and choose the best fit for your application.

Specification callouts to watch

• Wheel diameter and ground clearance - affects obstacle capability.
• Motor voltage and gear ratio - match to your battery and speed/torque needs.
• Mounting hole patterns - ensure compatibility with microcontrollers and sensors.

Accessory bundles and compatibility guidance

To speed builds, choose pre-curated bundles that pair chassis, motor drivers, wheels and a basic controller. Common controller pairings include Raspberry Pi and Arduino-compatible boards; check motor driver voltage ranges before pairing. We also stock popular maker accessories and sensors so you can add line-following, distance sensing or remote control without sourcing multiple suppliers.

Selection checklist, simple calculations and wiring basics

Quick selection checklist

• Project weight (chassis + payload) - select motors with enough stall torque.
• Desired speed and battery life - calculate current draw to size battery capacity.
• Mounting space for controllers and sensors - verify plate dimensions.

Useful formulas

Ohm’s law and power calculations help you match motors, drivers and batteries:

V = I × R - voltage, current and resistance relationship.

P = V × I - electrical power in watts. Example: a 6 V motor drawing 1.5 A consumes 9 W.

Simple DC motor wiring diagram (ASCII)

Battery + ----> Motor +

Battery - ----> Motor -

For controlled direction and speed use an H-bridge or motor driver module between your controller and the motor. Check motor driver voltage/current ratings against your motor specs.

Troubleshooting common issues

• Chassis sluggish? Verify battery charge and voltage sag under load.
• Uneven drive? Check wheel slip, gearbox backlash or mismatched motors.
• Sensors unstable? Isolate sensor power or add decoupling capacitors.
