An Automatic Electromechanical Front Wheel Locking System for a Rollator

Rollators are a popular mobility aid that help individuals with balance or walking difficulties move more safely and independently. Instead of a traditional walker, a rollator has wheels on all its legs, and brakes for the rear wheels only. When a user sits down or stands up using the rollator, unintended movement can cause falls. Locking the front wheels can help stabilize the rollator during these transitions. Therefore this project enhances a rollator by integrating electromechanical systems to improve this flaw. It features an automatic electromechanical locking system for the front swivel wheels, using two linear actuators to engage a cylindrical piston to prevent movement. This braking system is activated when the user activates the parking brake for the rear wheels.
