Many elderly people rely on a wheeled walker (ie. rollator) to help them maintain balance while walking to a desired destination. Travelling down slopes or through uneven surfaces may be necessary during the trip; this is strenuous to the femoral-patellar joint since the generated forces are comparable to running. Brakes can help increase safety and comfort in these situations. Many conventional rollators have a very basic manually controlled braking mechanism which presses a piece of metal into the wheel that in turn stops the rollator. Dirt or mud on the wheel can adversely affect the performance of this brake and some individuals may not have the necessary grasping strength to pull the brake wire effectively to control speed. Rolada offers an automatically controlled braking resistance to the wheels according to the slope and velocity of the rollator, providing a safer and more enjoyable trip for the user.
Undergraduate Engineering students are required to complete a group-based, two-course capstone sequence: ENSC 405W and ENSC 440. Groups form company structures and create an innovative product that potentially acts as a solution to a real-life problem. This collection archives the following assignments: proposal, design specifications, requirements specifications, and proof of concept.
