AI Technical Summary
Existing tracked remote-controlled lawnmowers are prone to slipping on slopes and lack effective brakes, especially on slopes of 20 degrees or more, posing a safety hazard. Furthermore, existing mechanical brakes suffer from severe wear and tear, resulting in high maintenance costs.
Electromagnetic braking is adopted, which uses the magnetic repulsion between the electromagnet and the brake pads to achieve rapid braking. Combined with a brushless motor and reducer, the braking and release can be remotely controlled through a wireless communication device, avoiding mechanical contact wear.
It improves the safety and ease of operation of lawnmowers under complex working conditions, reduces accident risks and maintenance costs, and enhances the flexibility and convenience of the device.
