Intelligent wheelchair obstacle avoidance design based on microcontroller

With an ageing society and an increasing number of disabled people, as well as a shortage of caregivers, there is a growing demand for rehabilitation aids in society. Intelligent robotics has been widely used in many fields, and the application of this technology in the design of smart wheelchairs can help improve mobility for elderly and disabled people who need mobility assistance. Smart wheelchairs are intelligent and autonomous, capable of performing operations such as obstacle avoidance and steering to meet the mobility needs of the user[1] . As smart technology continues to develop and innovate, the smart wheelchair will be further improved and promoted. It is developing in the direction of being smarter, more convenient, more comfortable and more humane, making a positive contribution to the well-being of society [2-5].
