1.Drive function: When the sweeping robot needs to move from the living room to the bedroom for cleaning, the motor drives the left and right wheels to rotate at a suitable speed and direction to drive the robot forward. 2.Balance function: The state with the ground can be adjusted according to the ups and downs of the ground to prevent the robot from tipping over and ensure the normal progress of the cleaning work. 3.Steering function: The left and right wheels can reach different speeds, and the direction of travel of the sweeping robot can be changed through differential steering. When cleaning furniture edges or bypassing obstacles, the angle can be precisely adjusted to ensure that every corner is clean. 4.Antislip function: Provide enough grip to avoid the robot slipping due to slippery ground or excessive motor torque during the cleaning process, so as to ensure that the robot can follow the predetermined route stably.
