Product Overview
JY Robot differential drive modules integrate twin drive wheels, servo motors, reduction gearing and a modular mounting structure. Vehicle travel, turning and pivot rotation are achieved by controlling the speed difference between the two driven wheels.
The series is available with multiple wheel diameters, motor powers, gear ratios, load capacities and tractive-force configurations. It is suitable for underride AMRs, warehouse transport robots, production-line logistics platforms and medium- to heavy-duty mobile equipment.
Motor, encoder, brake, wheel tread and interface configurations can be selected according to vehicle load, travel speed, installation space, floor conditions and control architecture.
AGV Differential Drive Wheel Module for 1–8 Ton Platforms
For AGV and AMR chassis, a differential drive wheel module uses two independently controlled drive wheels to provide straight travel, turning and zero-radius pivoting without a separate steering mechanism. This makes the architecture suitable for low-profile mobile robots, warehouse transport vehicles and heavy-duty material-handling platforms where chassis space and load capacity are important.
JY Robot offers dual-wheel differential drive units covering 1,000 to 8,000 kg load capacities with multiple wheel diameters, motor powers, gear ratios and tractive-force configurations. Selection should be based on driven-wheel load, required travel speed, acceleration, gradeability, floor condition and available installation space rather than vehicle gross weight alone. Motor, encoder, brake and wheel-tread options can be matched to the vehicle and control system.

Project Supply & Customization
JY Robot supports AGV and AMR manufacturers from prototype development through pilot batches and series supply. For heavy-duty differential drive projects, we can review vehicle load, required tractive force, travel speed, installation envelope, voltage and control requirements before model selection.
Standard configurations can be adapted for mounting interface, wheel specification and project integration requirements. CAD files and engineering review are available for qualified projects before ordering.
