An exoskeleton boot that can be selectively coupled to and decoupled from a lower link of an exoskeleton includes an upper configured to receive a foot of a human user and an outsole coupled to the upper. An exoskeleton connection interface is structurally coupled to the outsole and has a locked mode and an unlocked mode. In the locked mode, the exoskeleton connection interface is configured to inhibit decoupling from a boot connection interface of an exoskeleton link. In the unlocked mode, the exoskeleton connection interface is configured to facilitate decoupling from the boot connection interface.

Exoskeleton boot and lower link

A counterbalance system for an exoskeleton is provided, including a first hip joint to displace an external load experienced by a user above a waist of the user, the first hip joint provides for three degrees of freedom of movement, a tool interface located above the first hip joint to direct load displacement through the first hip joint, and a counterbalance arm having a first end and a second end, the counterbalance arm is secured to the tool interface at the first end, the second end of the counterbalance arm is moveable in an arcuate rotational path ranging from in front of the tool interface to behind the tool interface. Another system and method are also provided.

Exoskeleton system providing for a load transfer when a user is standing and kneeling

An exoskeleton system is disclosed including a hip joint to provide anatomically emulating three degrees of freedom of movement of the hip joint at a hip location of a user, a knee joint to provide anatomically emulating forward and backward movement of the knee joint at a knee location of the user, an ankle joint to provide anatomically emulating forward and backward movement of the ankle joint at an ankle location of the user, a knee rocker arm as part of the knee joint to transfer a load to a ground surface when the knee rocker arm is in contact with the ground surface as manually powered by the user, and a ground rocker arm as part of the ankle joint to transfer the load to a ground surface when the ground rocker arm is in contact with the ground surface as manually powered by the user.

An intermediate link for a tool arm assembly is provided. The intermediate link includes first and second connectors that are at least partially rotatable about respective first and second rotation axes. The intermediate link includes first and/or second lock rotation mechanisms that are configured to selectively prevent rotation of the first and second connectors.
