“…These motions can be performed mainly through the shoulder extension/flexion, upper arm internal/external rotation, elbow flexion/extension, and finally wrist supination/pronation. Whereas the omission of the shoulder abduction/adduction is limiting the flexibility, a previous biomechanical study conducted at our lab [44] investigated the effects of locking the shoulder abduction/adduction joint and showed that the joint was not necessary to perform simple ADLs. In addition to the obvious advantage of reducing the "bulkiness" around the shoulder gained from omitting the shoulder adduction/abduction, this also has other advantages.…”

This paper presents the EXOTIC- a novel assistive upper limb exoskeleton for individuals with complete functional tetraplegia that provides an unprecedented level of versatility and control. The current literature on exoskeletons mainly focuses on the basic technical aspects of exoskeleton design and control while the context in which these exoskeletons should function is less or not prioritized even though it poses important technical requirements. We considered all sources of design requirements, from the basic technical functions to the real-world practical application. The EXOTIC features: (1) a compact, safe, wheelchair-mountable, easy to don and doff exoskeleton capable of facilitating multiple highly desired activities of daily living for individuals with tetraplegia; (2) a semi-automated computer vision guidance system that can be enabled by the user when relevant; (3) a tongue control interface allowing for full, volitional, and continuous control over all possible motions of the exoskeleton. The EXOTIC was tested on ten able-bodied individuals and three users with tetraplegia caused by spinal cord injury. During the tests the EXOTIC succeeded in fully assisting tasks such as drinking and picking up snacks, even for users with complete functional tetraplegia and the need for a ventilator. The users confirmed the usability of the EXOTIC.

This paper presents EXOTIC, a revolutionary assistive upper-limb exoskeleton that offers previously unheard-of levels of control and versatility to people with total functional tetraplegia. While the context in which these exoskeletons should work is less or not prioritized despite posing significant technical needs, the exoskeleton literature in publication mostly concentrates on the fundamental technical components of exoskeleton design and control, ranging from fundamental technical features to practical real-world applications. The EXOTIC includes a lightweight, safe, wheelchair-mountable, and simple-to-put-on-and-take-off exoskeleton that can assist individuals with tetraplegia in multiple highly desired activities of daily living, a semi-automated computer vision guidance system that the user can activate when appropriate, and a tongue control interface that enables complete, conscious, and ongoing control over every movement the exoskeleton is capable of. Ten healthy participants and three users suffering from tetraplegia due to a spinal cord injury participated in the EXOTIC testing. Throughout the trials, EXOTIC was able to help individuals with total functional tetraplegia and ventilator dependency execute tasks like drinking and getting snacks. The utility of the EXOTIC was attested to by the users.
