A system for multi-axis self-climbing tree trimmer including a self-climbing platform, a motorized carrier, and a trimming portion. The trimming portion includes a base, an actuator with an extendable piston, one or more articulating arms having a curved configuration to receive a tree trunk or to form a central opening to substantially encircle a tree trunk. Each articulating arm includes one or more interchangeable cutting tools for tree trimming and one or more cut depth control elements for controlling the depth of engagement of the cutting tools. The base may include a wheel element to indicate pressure exerted by the actuator. The extendable piston is coupled to the articulating arms, wherein when the extendable piston extends, the articulating arms move to an open configuration, and when the extendable piston retracts, the articulating arms move to a closed configuration, and the articulating arms may move independently of each other.

A robotic pruning apparatus that can be adapted to fit around a variety of trees and can move along the length of the tree while performing a variety of pruning operations. The pruning apparatus can be configured with a variety of different cutting heads that have multiple degrees of freedom of movement such that they can be used to perform any number of cutting operations along the length of the tree. The apparatus can be remotely operated by a human or can be autonomous or semi-autonomous.

An apparatus designed for climbing poles, trees and other such columnar objects. The apparatus is a remote-controlled work station that provides a scaffold for mounting semi-robotic articulated arms and video cameras. The articulated arm has a quick-release coupler on an end thereof that is able to repeatedly and releasably couple attachments thereto, such as saws, blades, and other pruning objects. The device includes an expandable frame that may be opened and closed to fit around the vertical structure to be climbed. The frame has horizontal and vertical supports, drive system compression supports, and wheels. A drive system is mounted to each of the drive system compression supports. The drive system includes motorized tracked-climbers that are maintained in contact with the vertical structure to be climbed via adjustable independent suspension. The suspension uses adjustable spring shocks and drive system slide rails to connect the frame to the drive system.

A device for allowing work to be carried out on or about an object includes at least one gripping arrangement. The at least one gripping arrangement is configured to grip and traverse the object so as to reach a desired location on the object and to anchor the device thereto for allowing the work to be carried out.

A remote-operated palm tree trimming system and apparatus, configured to ascend a palm tree safely via treaded tires and trim the tree via at least one saw blade. The tires are disposed in communication with actuators which apply pressure against the trunk of the tree, ensuring that the tires maintain adequate grip to overcome gravity during ascent. A remote control, operated by user on the ground, enables control of the wheels, actuators, and saw blade, facilitating manipulation of the device to effectively trim the tree remotely, ensuring the safety of the operator.
