Fire-fighting operations need to carry certain operating modules and special rescue equipment, and can drag the full range of long-range fire hose, which requires fire robot chassis must have good dynamic performance, load capacity and expand ability, the robot chassis Of the power system uses a large capacity battery plus AC motor type, the control module based on the CAN distributed modular design, making it with strong power and agile rapid motor performance, the results can bear 350kg of load, climbing 30 of the slope, climbing 60 cm vertical obstacles, but also have dragged two 100m pipes full of water to walk, in the muddy land and 30 slope on the original turn and other excellent performance.
