Black aluminum four-wheel robot chassis kit with 66mm tires, unassembled

LORDWORLD

LORDWORLD 4WD Smart Chassis Car Kit Black Unassembled 66mm Wheels 180x140x89mm 1500g Load

SKU CH-F929-0JKNJ

Four-wheel-drive robot chassis kit with aluminium frame, four TT gear motors and 66 mm wheels supports up to 1500 g load

  • Simple mechanical structure makes assembly convenient
  • Four TT DC gear motors deliver strong driving force
  • 1:120 gear reduction ratio provides high torque for heavy loads
  • Anti-skid 66mm tyres improve traction on varied surfaces
  • Sturdy aluminium alloy chassis supports up to 1500g payload

4WD Smart Chassis Kit

The LORDWORLD kit provides an unassembled four-wheel-drive robotic platform built from aluminum alloy. It includes four TT DC gear motors paired with 66mm anti-skid tires and a 1:120 reduction ratio for increased torque. The chassis measures 180 by 140 by 89mm and supports a maximum load of 1500g. Simple mechanical structure makes assembly straightforward for hobbyists.

Suits DIY robotics learners

This kit suits makers and students building a mobile robot base for experimentation or education. The four-motor layout delivers strong driving force on varied surfaces. It is not for buyers who need a ready-to-run vehicle, integrated electronics, wireless control or a higher load rating than 1500g. Builders requiring a different wheel diameter, motor voltage or encoded feedback should look elsewhere.

Check motor driver and power

Verify that your chosen motor driver can handle four TT gear motors at the required voltage and current. Ensure your battery or power supply fits within the 180 by 140mm deck and can sustain the stall current of all motors. Confirm the mounting pattern matches your controller board and sensor hardware. Plan for wiring routing before final assembly.

Questions about this item

What controller or driver board do I need to run the four 1:120 TT gear motors?

Any board that can supply the voltage and current each motor draws — common choices are an Arduino with a dual H-bridge shield, a Raspberry Pi with a motor HAT, or a dedicated motor-driver module.

Will the 66 mm wheels and 180×140×89 mm aluminium chassis fit the sensor mounts and battery packs I already use?

The chassis has standard mounting holes and a 1500 g load rating, so most hobby sensor brackets and Li-ion or NiMH packs within that weight will bolt on directly.

How can I verify the 1:120 reduction is delivering the expected torque after assembly?

Apply a known voltage, measure the no-load wheel speed, then stall the wheel gently and confirm the current draw matches the motor’s rated stall current for that gear ratio.
