Abstract: A caster apparatus is provided. In one embodiment, there is provided a caster apparatus including a caster wheel and a first driving wheel disposed on a first side of the caster wheel. The first driving wheel is configured to be driven by a first motor. A second driving wheel is disposed on a second side opposite to the first side of the caster wheel. The second driving wheel is configured to be driven by a second motor different from the first motor. A first actuator is configured to move the first driving wheel in a vertical direction to a ground according to a curvature of the ground. A second actuator is configured to move the second driving wheel in a vertical direction to the ground according to a curvature of the ground, wherein the first and second driving wheels are configured to steer the caster wheel.
