What is the working principle of intelligent robot wheelchair?

Some elderly people and people with disabilities cannot live independently due to physical reasons, while ordinary wheelchairs have a single function and cannot change their quality of life and freedom. Therefore, research on intelligent robotic wheelchairs used to help disabled people to walk has gradually become a hot topic.

Intelligent robot wheelchair function

The intelligent robot wheelchair is an improvement to the traditional electric wheelchair. DSP is used as the core controller, and the fuzzy control theory is applied to realize the real-time obstacle avoidance function of the wheelchair in a specific mode. The application of intelligent wheelchairs to embedded technologies enables them to have low power consumption and high computing performance. It can help the elderly and the disabled to live independently, save the cost of home care, and reduce the social burden.

Intelligent robot wheelchairs mainly include password recognition and speech synthesis, robot self-positioning, dynamic random obstacle avoidance, multi-sensor information fusion, and real-time adaptive navigation control.

Intelligent robot wheelchair application principle

The key technology of robotic wheelchairs is the problem of safe navigation. The basic method used is to rely on ultrasonic and infrared ranging. Individual password control is also used. The main drawback of ultrasonic and infrared navigation is that the controllable measurement range is limited, and visual navigation can overcome this deficiency. In robotic wheelchairs, the user of the wheelchair should be the central and active part of the entire system. For the user, the robotic wheelchair should have the ability to interact with people. This interactive function can be intuitively implemented through human-machine voice dialogue. Although individual existing mobile wheelchairs can be controlled with simple passwords, mobile robots and wheelchairs with truly interactive features are still rare.

At present, the technical level of intelligent wheelchairs has yet to be improved, but with the development of science and technology, smart wheelchairs must be able to be more convenient and safe, or even completely replace lower limbs for activities.
