Abstract: A robotic apparatus for treatment of at least one body part of an animal including a device that treats the body part, a device that detects the body part, a robot arm including a plurality of robot arm parts and a plurality of hydraulic actuators for mutually displacing and positioning of the robot arm parts, at least two of the plurality of hydraulic actuators being independently controlled electro-hydraulic actuators, and a controller configured to control the hydraulic actuators to assist the robot arm in bringing the robot arm part having a treatment device to the body part in response to feedback from the detection device.

Abstract: An apparatus for facilitating a controlled descent of a body is disclosed. The apparatus includes a rotatable reel around which a portion of a cable is wound, a first end of the cable secured to the reel and a second end of the cable free; a friction drum around which a portion of the cable, is wound; a carrier on which the reel and the drum are mounted, a braking mechanism for braking rotational motion of the reel and for balancing descending speed of the body; a harness, for harnessing the device to the body; and a damping mechanism for damping the initial impact.

Abstract: A device for facilitating a controlled descent of a body, the device comprising a rotatable reel around which at least a portion of a cable is wound, a first end of the cable secured to the reel and a second end or the cable free; a friction drum mounted coaxially around the reel, the cable, upon leaving the reel wound at least partially around the drum; a carrier on which the reel and the drum are mounted; wherein the reel is provided with braking means for braking rotational motion of the reel and for balancing descending speed or the body.
