Title: Aerial carrier device
Inventor: WADA HIROSHI
IPC: B25J15/08
Filed: 2020-03-04
Abstract: To provide an aerial carrier device that carries an object to be carried to run over an obstacle.SOLUTION: It can be suggested that an aerial carrier device carries an object to be carried sideways or with a certain angle while making a robot hand grip the object, in order to avoid a shape of the object to be carried or an obstacle, where the robot hand is turned around a horizontal axis 20 by driving a first motor 27. When the robot hand is turned around the horizontal axis 20, a position of gravity of the whole of the aerial carrier device changes and therefore the aerial carrier device swings substantially, which disables the device to move stably. Therefore, a second motor is driven to prevent balance of the whole of the aerial carrier device from being lost. More specifically, the second motor is driven to move weight so that the weight moves to a position where load torque acting on the first motor 27 generated by tilting of the robot hand becomes zero.SELECTED DRAWING: Figure 6
