High reliability
The robot chassis is designed with six vehicle-level independent modules and supports IP67 protection level, with stable performance and high reliability. The chassis frame is integrally welded, lightweight and stable, and can meet various harsh environment applications.
High precision control
The robot chassis uses a multi-pole hub motor and a high-power-density motor driver. The motor integrates photoelectric and Hall encoders. The precise position information of the rotor is obtained through a fusion algorithm. The driver uses advanced data fusion and interpolation algorithms to improve the position signal resolution. This enables high-precision driving control.

High flexibility
The chassis adopts a steering gear controller, four-wheel independent high-precision steering gear and adjustable suspension, which can realize turning in place and small-radius turning while walking, making the turning smooth and flexible. It can adapt to turning and passing on various narrow road sections.
Strong load-bearing capacity
The robot chassis adopts a high-power power system, integrates multiple overload protections, supports twice the rated load of its own weight, is suitable for carrying various types of equipment, and is highly expandable.
