Abstract
A dolly capable of preventing spinning and performing appropriate rotation is provided. The dolly (1) includes a dolly body (2), a plurality of wheels (3), a drive unit (4) that drives each wheel, a handle (5) that receives an operation of a user, an input detection sensor (6) that detects a load and / or torque applied to the handle, a rotation speed sensor (7) that detects a rotation speed of each wheel, and a control device (8) that sets a target propulsion force that should be output from each wheel as a propulsion force based on the load and / or torque, and controls the drive unit to output the target propulsion force as the propulsion force, and the control device sets the target propulsion force of the wheel located on a side away from a rotation center to be smaller than the target propulsion force set based on the load and / or torque in a case where the rotation speed of the wheel located on a side close to the rotation center exceeds a prescribed threshold value at the time of rotation.
