Requirement analysis
Product Analysis
Key Points of the Requirement
Define payload capacity (from 50kg to 1,000kg+), driving speed, climbing ability and ground clearance, and the drive configuration (two-wheel differential, four-wheel differential, Mecanum or omnidirectional, steering-wheel type, or tracked). Specify navigation sensor mounting provisions (LiDAR, SLAM, QR-code), battery capacity and charging approach (manual plug or auto-dock), indoor or outdoor use, IP rating, and the openness of the control interface (CAN/EtherCAT, ROS driver) for integrating your own controller or upper computer.
Cost Structure Analysis
Drive units (hub or geared motors with encoders) and the battery pack typically account for half the cost, followed by the welded and machined frame, motor drivers and controller, wheels and casters, and cabling. Navigation sensors are commonly excluded and priced separately. Frame welding and machining tooling is amortized in the first batch, and higher volumes reduce both mechanical and electronics unit cost significantly.
Estimated Cost Range
Indicative factory pricing: compact indoor differential chassis (100kg class, without navigation sensors) $800–$3,000 per unit; mid-range (300–600kg) $2,000–$6,000; heavy-load or Mecanum configurations $4,000–$10,000; outdoor tracked or off-road chassis $6,000–$15,000. Quantities of 50–100 units typically improve pricing by 15–25%. Final quotations depend on drive configuration, battery size, and structural complexity.
Procurement Considerations
Prioritize chassis makers who publish continuous-operation test data (runtime at rated payload, motor temperature rise), use branded motors and drivers, and provide open communication protocols with ROS drivers. Confirm battery certification (UN38.3) for shipping, spare-parts supply for wheels and drive units, and customization willingness for mounting patterns. Witness an acceptance test on payload, slope, and runtime before shipment, and clarify warranty terms, training or documentation inclusion, packaging, Incoterms, and delivery destination.
