Robot Tank Chassis Kit

This robot tank chassis kit is a modular intelligent mobility platform primarily designed for applications such as smart lawn mowing, multi-purpose inspection, firefighting robots, agricultural plant protection, and scientific research. It is particularly suited for use on steep slopes (up to 30° incline), grassy terrain, muddy surfaces, slippery ground, narrow greenhouse aisles, high-humidity or coastal regions, areas with frequent pesticide/fertilizer spraying, as well as tree-canopy shaded or indoor environments where GPS signals are limited. The system features an IP55 protection rating and a 200kg payload capacity, supporting heavy-duty mowing units, sensors, water tanks, robotic arms, and other task modules. It withstands rain, high-pressure washing, chemical corrosion, and condensation caused by diurnal temperature fluctuations.

Why choose servo motors as the drive system?

The servo motors matched to this robot tank chassis kit are high-performance closed-loop control motors powered by 48V DC, with a rated output power of 2000 watts. They enable millimeter-level positioning, smooth start/stop, and constant-speed operation (even with load variations), ensuring stable and precise movement across complex terrains such as slippery grassy slopes, muddy field ridges, and sandy inclines.

1. Compared to brushed DC motors or standard brushless motors, servo motors offer higher efficiency (typically >85%) at equivalent output, minimizing energy waste and extending battery life.

2. Supports control signals including CANopen, Modbus, PWM, and analog inputs, enabling seamless integration with master controllers (e.g., PLCs, ROS controllers, embedded computers); Simultaneously, they enable real-time transmission of motor status (temperature, current, RPM, fault codes) for system monitoring and predictive maintenance.

3. Incorporate multiple protection mechanisms, including overcurrent, overvoltage, overheating, stall, and short-circuit safeguards.  During sudden obstacles or emergency stops, they respond rapidly and halt safely, effectively preventing damage to the transmission system or injury to nearby personnel.

Supports 360° on-the-spot rotation (zero turning radius): The entire machine can rotate around its geometric center to any angle without lateral displacement, even performing continuous turns, achieving a turning radius of zero.

1. Ultimate Spatial Adaptability: Freely reverses direction in passages only slightly wider than the chassis itself, such as narrow working aisles in vegetable greenhouses (typically <1.2 meters wide); gaps between shrubs and flowerbed-enclosed areas in landscaping; equipment aisles in industrial plants or warehouses; debris gaps or indoor corridors in firefighting or rescue scenarios.

2. High-Precision Directional Control: Leveraging servo motors' closed-loop control capabilities, it achieves angle positioning accurate to within 1°; during autonomous navigation (e.g., RTK or laser SLAM-based), it rapidly aligns with the target heading to minimize path tracking errors.

3. Low Ground Disturbance & Slip-Free Steering: The tracked design, combined with differential reverse operation, enables steering primarily through rolling friction rather than sliding friction, significantly reducing damage to sensitive surfaces like lawns, plastic mulch, and flooring. Compared to traditional wheeled zero-turn mowers (which steer by wheel slippage), tracked systems offer smoother, more energy-efficient, and less wear-intensive on-the-spot turning.

4. Enhanced System Robustness and Safety: When encountering sudden obstacles or narrow bottlenecks, the system can adjust orientation on the spot to find an escape route, avoiding entrapment or collisions. During firefighting or inspection tasks, sensors or operational modules (e.g., cameras, water cannons) can be rapidly aligned with the target direction, improving response speed.

The essence of electrical and communication modularization lies in “standardization + openness.” It not only transforms robot chassis from “closed hardware” into “open platforms,” but also significantly lowers the development barriers, integration risks, and total lifecycle costs of intelligent mobile systems.

1. Multi-channel Power Output: Beyond the primary 48V drive, it provides 12V/24V auxiliary power interfaces (with overcurrent protection) to directly power peripherals like sensors, cameras, lighting, and water pumps. Supports real-time reporting of battery status (SOC/SOH) via CAN or RS-485 for convenient energy management by host computers.

2. Unified Control Bus: The dual-drive controller not only manages chassis motion but also serves as a communication hub, supporting:

CAN Bus: Connects to industrial devices like LiDAR, IMU, and safety PLCs;

RS-485: Interfaces with traditional agricultural instruments and environmental sensors;

PWM/IO Signals: Controls actuators such as solenoid valves, relays, and warning lights.

Users can read chassis status (speed, angle, fault codes) and issue motion commands via unified protocols (e.g., custom CAN IDs or Modbus registers).

3. Supports ROS/SDK Development:

Provides low-level driver packages and API development kits for researchers to rapidly integrate SLAM, path planning, AI recognition, and other algorithms;

Serves as a mobile robot tank chassis teaching or competition platform, supporting progressive development from basic remote control to fully autonomous navigation.

This robotic chassis boasts core advantages, including 30° incline climbing capability, IP55 protection, 200kg payload capacity, precise low-speed operation from 0–3 km/h, zero-turn maneuverability, and multi-protocol control. It not only meets the demands of smart lawn mowers for navigating complex terrain, high-humidity environments, and safe operation, but also serves as a highly reliable mobile platform. This platform supports in-depth development and customized applications across firefighting, inspection, agriculture, and scientific research sectors.
