Design and implementation of automatic following wheelchair

Abstract

According to the fact that electric wheelchairs rarely have anautomatic specific follower in the market, and to lighten the burden of escorts, we have designed a mechanized following wheelchair based on Bluetooth and attitude sensor. The wheelchair is mainly composed of sending device and receiving the device. The escort carries the sending device, and the receiving device is installed in the wheelchair. The transmitter can transmit the carrier’s attitude sensor information and step number information to the Bluetooth receiving module of the wheelchair in real time through Bluetooth. The wheelchair control core can compare its attitude sensor information with the received attitude information of escort personnel. Through the control of the wheelchair motor driving module, the wheelchair can automatically follow the specific escort personnel.
