To provide a robot controller configured to reliably receive data from a robot even when there is a shield. A robot controller receives a signal transmitted by a wireless device mounted to a robot that is a control target. The signal includes data of an operating state of the robot. The robot controller includes: a first receiving unit that receives the signal including the data from the wireless device; a transfer unit that, in a case in which the signal received by the first receiving unit is a signal from other robot not to be controlled, transfers the signal to other robot controller controlling the other robot; a second receiving unit that receives the signal transferred from the other robot controller; and a signal processing unit that processes the signal received by the first receiving unit and/or the signal received by the second receiving unit.

A technique provides for wireless control of a machine tool, e.g. a portable machine tool used on-site. According to an embodiment, a motor is connected with a tool post assembly via a gearbox. The motor is coupled with a machine controller, and the tool post assembly is mounted proximate an object to be machined. For example, the object may be machined via a cutting tool mounted to a cutter post of the tool post assembly. The machine controller operates to control movement of the cutter post along a desired axis during the cutting operation. The machine controller and thus the cutting operation, however, are controlled wirelessly according to control instructions provided via a control device, e.g. a handheld control device, which is placed in wireless communication with the machine controller.
