Obstacle Avoidance System for the Wheelchair-Mounted Robotic Arm

The wheelchair mounted robotic arm (WMRA) is designed for a person in a wheelchair who also has limited to no use of their arms to autonomously move around and assist the use in activities of daily living (ADL). While moving around the room autonomously, the WMRA will need an obstacle avoidance system so it does not collide with anything while it makes its route to its final destination. My project is to design a schematic and then construct a mount for the eleven proximity sensors, eight in the front and three in the back, needed on the WMRA so that it can perform this task of autonomously avoiding obstacles. Once these sensors are added, the WMRA will be able to sense when something is nearby, and then change route to avoid the object and complete its task and reach its final destination
