After taking the time to look at our initial design for our problem, we noticed that building a prototype for the exoskeleton would be too difficult and too time consuming. Plus the ease of use would be too difficult for the patient trying to operate the device. After deciding to find an alternative way to approach the problem, we came up with another design, that is much simpler to builder and is more accessible for the patient, and it still allows the problem to be solved. The new design is based off of the design for an extending grabber, which is a mechanism that is used to grab items that may be out of reach, such as wires, balloons, tools, boxes, etc., with much more ease. See the figure below.

For our design, we will be eliminating the whole extended grabber mechanism, except for the head, which will basically be used as the whole mechanism for our project.The basic design for our new approach is that, two magnets will be placed on a door; one above the key hole, and one below. According to your height or ease of use, you can place the two magnets at any distance apart (with in reason). Likely, another two magnets will be attached to the prong like extenders of the head. These will attach to the magnets already on the door, allowing the mechanism to be stable while being used. Next, in the middle of the device, there will be a large round casing that will house the key for the lock. The key will be attached to a smaller casing that is free to rotate, using a dial like device on the back of the head, at the end of the second casing, so you're able to turn the key, to unlock the door. The smaller casing will be retractable so that once the key is taken out of the hole, the key goes back into the mechanism, inside the casing. See the figure below for a better understanding of how the device will look.
