Abstract
A robot system includes a mobile robot provided with a driving wheel and a driving motor, a load cell provided in the mobile robot, a spring connected to the load cell, an auxiliary wheel connected to the spring, and a controller configured to change a speed of the driving motor according to a sensing value of the load cell.
Claims20
A robot system comprising:
- a mobile robot provided with a driving wheel and a driving motor;
- a load cell provided in the mobile robot;
- a spring connected to the load cell;
- an auxiliary wheel connected to the spring;
- and
- a controller configured to change a speed of the driving motor according to a sensing value of the load cell.
3 more elements
A robot system comprising:
- a mobile robot provided with a driving wheel and a driving motor;
- an auxiliary wheel;
- an auxiliary wheel sensor installed in the mobile robot and connected with the auxiliary wheel to sense a movement speed of the auxiliary wheel;
- and
- a controller configured to:
- accelerate the driving motor if the movement speed of the auxiliary wheel is higher than a movement speed of the mobile robot after the auxiliary wheel enters a moving walkway, and
- decelerate the driving motor if the movement speed of the auxiliary wheel is lower than the movement speed of the mobile robot after the auxiliary wheel enters the moving walkway.
4 more elements
A method of controlling a robot system including a mobile robot provided with a driving wheel and a driving motor, the method comprising:
- sensing a movement speed of an auxiliary wheel by an auxiliary wheel sensor installed in the mobile robot;
- performing a speed changing process of accelerating the driving motor if a movement speed of the auxiliary wheel is higher than a movement speed of the mobile robot after the auxiliary wheel enters a moving walkway and decelerating the driving motor if the movement speed of the auxiliary wheel is lower than the movement speed of the mobile robot after the auxiliary wheel enters the moving walkway.
