Electric Wheelchair Controller with Joystick and Speed Limiting

Approx. component budget: Rs. 9,000 - 15,000

Objective

Build a smooth and safe controller for a small wheelchair-type platform and measure its acceleration, stopping distance and battery use.

What you will build

A joystick input, a dual-channel motor controller for two geared DC motors, a microcontroller with ramp and speed-limit logic, an obstacle sensor, an emergency stop and a battery.

Results you can expect

• Speed response to joystick
• Acceleration ramp
• Stopping distance with and without the obstacle sensor
• Battery current and run time

What you will learn

Motor control, safety logic and assistive device design, an area with growing demand.

Tools and notes

Arduino/ESP32, dual motor driver, joystick, ultrasonic sensor, battery. Build and test on a model platform before any human use, and always include an emergency stop.

Resume points from this project

• Built and tested Electric Wheelchair Controller with Joystick and Speed Limiting; objective: build a smooth and safe controller for a small wheelchair-type platform and measure its acceleration, stopping distance and battery use.
• Measured and analysed speed response to joystick and acceleration ramp; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
