Development of a Mechanism to Dock a Robotic Self-Transfer Device to a Wheelchair

A Robotic self-Transfer device was developed to transfer individuals with lower limb disabilities from a wheelchair to any other surface and vice versa on his/her own without a caregiver’s support. The device is aimed at providing independence and privacy to people with disabilities in performing day-to-day activities. This device was designed in such a way that it can be attached or detached, i.e. docked or undocked, to/from the wheelchair whenever necessary. In the existing design, the docking and undocking of the self-transfer device to the wheelchair is found to have some limitations in certain scenarios. Hence, this paper discusses development of a new mechanism to enable easy attachment and detachment of the self-transfer device to/from a wheelchair. Initially a conceptual design of the docking mechanism was formulated, later the design was 3D printed, further it was automated and subsequently it was implemented successfully in a Proof of Concept (PoC) test set up.
