Operator guidance functions for remote controlled demolition robots

A computer-implemented method, executed by a control unit arranged on construction equipment configured to receive control commands from a remote control device, the construction equipment comprising a tool arm rotatably supported on a tower,

• wherein a tool comprising opposing jaw members arranged movable in a jaw plane relative to each other is attachable at a distal end of the tool arm,
• wherein the opposing jaw members of the tool are rotatable about an extension axis of the tool by a rotation actuator,
• wherein the tool comprises a rotary encoder configured to determine a current rotation angle of the jaw plane relative to the tool arm, and to send a signal indicative of the current rotation angle to the control unit,
• the method comprising obtaining the signal indicative of the current rotation angle of the tool from the rotary encoder,
• obtaining a signal from the remote control device indicative of a desired tool rotation angle of the tool, and
• controlling the rotation actuator to reduce a difference between the current rotation angle and the desired rotation angle of the tool.

• the construction equipment comprising an environment sensor configured to observe a work object in vicinity of the construction equipment,
• the method comprising:
• receiving a command from the remote control device of the construction equipment related to the work object,
• receiving data related to an extension direction of the work object from the environment sensor, and
• triggering an automated guidance function involving rotation of the tool about the extension axis, by the rotary encoder, to position the opposing jaw members in relation to the work object.
