I heard about accidents in which a stroller fell from a railway platform because the wheels of the stroller were not locked. This made me think that it would be nice to create a stroller with an automatic braking system activated by taking one's hands off the stroller. Using a touch sensor kit, I added sensor functions to the handles by covering them with aluminum foil tape. The control device activated by holding and taking one's hands off the aluminum portion of the handles rotates the motor, which engages or releases the brakes.
