This paper uses mobile phone with LinkIt 7697 to control electric wheelchair, write a mobile app program using app Inventor 2, this program has Bluetooth connection, mobile phone positioning, mobile phone Orientation-sensor direction sensor and other functions, after the user opens the app and opens the remote control function, with the rotation of the left and right of the phone, the directional sensor transmits the current posture of the phone to LinkIt 7697, the servo motor driver is then controlled by LinkIt 7697, servo motor mounted on front wheel of electric wheelchair, after receiving the instructions of the drive, you can achieve the action of controlling the front wheel around the phone.
The rear wheel of an electric wheelchair is controlled by a dc24v DC motor, transmit the boot signal to the DC motor driver through the mobile app's instructions for moving forward back to LinkIt 7697, mobile phones can control the advance and retreat of wheelchairs, the mobile app also has the speed to control the travel of a wheelchair, divided into five levels from slow to fast.
MCS (MediaTek Cloud Sandbox) cloud platform developed by MediaTek, with LinkIt 7697, the current information of the electric wheelchair is transmitted to the MCS through WiFi, use the monitor's mobile app to learn remotely about the status of your current electric wheelchair.
