The robotic arm includes a distal end that is rotatable with respect to an axis of the robotic arm.

A motion limit is configured for at least one axis of said robot arm.

The drive arm is mounted to the drive frame for pivotal movement about a drive arm axis.

The tensioner arm is pivotally connected to the base for movement about a tensioner arm axis.

The axis of the handle (4) is located in the direction of the minor axis (3) of the transmission (1) and contains the angle α of -15 to +15 degrees with this minor axis (3).

The first arm center axis defines a center of the first arm and the second arm center axis defines a center of the second arm.

The second arm is configured to rotate about the first axis and a third axis.

The longitudinal axes are oriented by movement of the linkage arm about the first lateral axis and/or the second lateral axis.

The arm support member can be configured to rotate about an axis perpendicular to a longitudinal axis of the tensioner system and perpendicular to an axis of rotation of each of the arm members.

The contact surface (124) of the arm (12) is parallel or substantially parallel to a longitudinal axis (X12) of the arm.

A longitudinal boom axis (21) extends between the proximal and the distal ends of the boom and a cutting device (10) is pivotally mounted about a pivot axis (20) adjacent the distal end of the boom.

According to the invention, in the OFF position the rocker is oriented in such a way that a section of the rocker located above the first horizontal axis forms an overhang in relation to the section of the rocker located below the first horizontal axis.

The diverter arm includes a pivot member that defines a rotational axis of the diverter arm.

The robotic arm includes a distal end that is rotatable with respect to an axis of the robotic arm.

Each arm (12, 13) is parallel to the arm (16, 17) on the opposite side of the waist (15) and long axis.
