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.

Abstract: A driving tool includes a piston, a driver, and a lift mechanism. The piston moves in a driving direction by a pressure of a gas. The driver extends from the piston and includes a plurality of engaged portions. The lift mechanism moves the driver in a direction opposite to the driving direction. The lift mechanism includes a rotation shaft, a wheel, a plurality of engaging portions, and a supporting member. The wheel rotates integrally with the rotation shaft. Each of the plurality of engaging portions may engage an engaged portion. The supporting member supports the wheel so the wheel is allowed to move between an initial position and an eccentric position in a radial direction of the rotation shaft.

Abstract: A driving tool for improving shock absorbability and durability of a tubular damper, the driving tool comprising a cylinder and a piston that moves inside the cylinder owing to a gas pressure. The driving tool further comprises a driver main body to drive a driving member by moving integrally with the piston, and a lift mechanism having a wheel for the driver main body to return to original position. The driver main body is arranged such that a width center line of the driver main body is offset in a direction away from the lift mechanism with respect to a width center line of the piston.

Abstract: A battery pack includes a battery, a coupling portion, a connection determiner, a receiver, and a prohibition range controller. The prohibition range controller varies a prohibition range depending on the connection or non-connection of the electric work machine that is determined by the connection determiner, or the specification of the electric work machine connected to the coupling portion. The prohibition range is defined by a current range and a voltage range. A discharge from the battery is prohibited in the prohibition range.
