Abstract: A rebar tying robot may include a rebar tying unit, a conveying unit configured to convey the rebar tying unit, and a control unit configured to control the conveying unit. The conveying unit may include a longitudinal movement mechanism configured to move the rebar tying robot in a front-rear direction and a first three-dimensional distance sensor configured to output first point cloud data which represents a three-dimensional position of a subject in a first field of view by point clouds. The control unit may be configured to execute a first rebar extraction process in which the control unit extracts point clouds from the point clouds included in the first point cloud data and an intersection location identification process in which the control unit identifies a position where the primary rebar and the secondary rebar intersect based on the point clouds extracted in the first rebar extraction process.

Abstract: A rebar tying robot may include a rebar tying unit, a conveying unit configured to convey the rebar tying unit, and a control unit configured to control an operation of the conveying unit. The conveying unit may include a longitudinal movement mechanism configured to move the rebar tying robot in a front-rear direction, and a first three-dimensional distance sensor configured to output first point cloud data which represents a three-dimensional position of a subject in a first field of view by point clouds. The control unit may be configured to execute a first rebar extraction process in which the control unit extracts point clouds from the point clouds included in the first point cloud data and a rebar model generation process in which the control unit generates a rebar model based on the point clouds extracted in the first rebar extraction process.

Abstract: A rebar tying robot may include a rebar tying unit, a conveying unit, and a control unit. The conveying unit may include a longitudinal movement mechanism, a lateral movement mechanism, and a first three-dimensional distance sensor. The control unit may be configured to execute a first rebar extraction process in which the control unit extracts point clouds from point clouds included in the first point cloud data, a first judgement process in which the control unit judges whether the primary rebar exists within a predetermined judgement area based on the point clouds extracted in the first rebar extraction process, and a lateral movement process in which the control unit drives the lateral movement mechanism. When the control unit judges in the first judgement process that the primary rebar does not exist within the judgement area, the control unit may execute the lateral movement process.
