Problems solved by technology

The elderly and disabled people are generally lower than normal people in terms of mobility, reaction speed and thinking ability. If they only rely on the real-time manual operation of the user, it will not only cause fatigue of the user, but also be affected by the user's mobility and reaction. The influence of speed and control experience may make the control effect poor, and even cause safety accidents in severe cases
[0003] After many years of development, smart wheelchairs have made great progress in the research of control technology, but most of the smart wheelchairs are still insufficient in terms of stability and safety.

Description

technical field [0001] The invention relates to the field of wheelchairs, more specifically, to a new energy multifunctional wheelchair. Background technique [0002] The smart wheelchair combines robotics and electric wheelchair technology, and has better autonomy, interaction and adaptability, greatly improving its intelligence. The people who use smart wheelchairs are usually the elderly and the disabled. They are mainly designed as a means of transportation for this special group of people. Good walking ability should be the basis of their intelligence. Wheelchairs will inevitably encounter some obstacles in the process of autonomous walking. Fast and safe obstacle avoidance is a basic ability necessary for smart wheelchairs. The elderly and disabled people are generally lower than normal people in terms of mobility, reaction speed and thinking ability. If they only rely on the real-time manual operation of the user, it will not only cause fatigue of the user, but also ...
