  • Patent number: 11167414
    Abstract: A robot includes a robot body, a control processor, a detection circuit, a memory, and a determining circuit. The control processor is configured to control the robot body to perform a work on a workpiece while the workpiece is conveyed. The detection circuit is configured to detect external force which the robot body receives from the workpiece. The memory is to store a threshold force. The determining circuit is configured to determine whether the external force is equal to or larger than the threshold force.

  • Patent number: 8910538
    Abstract: A robot according to an embodiment includes a base, a first structure, a second structure, and a third structure. The first structure is connected to the base to be rotatable about a first axis. The second structure is connected to the first structure to be rotatable about a second axis orthogonal to the first axis. The third structure is connected to the second structure to be rotatable about a third axis parallel to the second axis. The first structure and the third structure are formed by using cast materials having a same shape.

  • Patent number: 8720296
    Abstract: A vertical articulated robot includes a base, a turning base, a first upper arm, a second upper arm, a front arm, a wrist assembly, a first motor, a second motor, a third motor, a fourth motor, and a wire body. The wire body includes a first wire portion, a second wire portion, a third wire portion, a fourth wire portion, a fifth wire portion, and a sixth wire portion. The first wire portion extends from the turning base along a third rotation axis and is connected to an outer surface of the first upper arm. The second wire portion extends from the first wire portion along a plane perpendicular to the third rotation axis and is connected to an outer surface of the first upper arm. The third wire portion extends in a U-shape from the second wire portion.
