Assistance dogs often do a lot for their owners, but for users with limited mobility, it is not always easy, or possible, for them to reward their dog. Our objective was to develop a solution to this problem. We developed a treat dispenser specifically designed for use by users of limited mobility. Specific goals included ensuring the device is wheelchair-mountable, reliable, and can be controlled through whichever medium the user is most able and comfortable using.
