Development of a Dual Control System Applied to a Smart Wheelchair, using Magnetic and Speech Control

The use of Power Electric wheelchairs for physically disabled people is becoming increasingly common; however the systems used in order to manage it are reduced to the use of specialized drivers, only using joysticks to manipulate the wheelchair, and these are generally suitable only for patients with motor disabilities in their lower limbs. This paper proposes the development of a speech control system and a magnetic control system to drive a wheelchair as an alternative for patients with severe disabilities. Both are applied to a smart wheelchair; the proposed systems include the development of new communication protocols for the wheelchair through a microcontroller, an H-bridge, a microphone and a magnetic control.
