Designing and constructing a speed control mechanism for an automatic wheel chair

---

The primary objective of this thesis is to design and construct a driving and steering with speed control for an automatic wheelchair. The driving and steering system with speed control will be used to help the users move in the desired direction. The braking system is also implemented to decelerate the speed of wheelchair. It is also aimed as a safety system on the ramp when the standing mechanism is applied. The automatic wheelchair can be moved in four directions, forward movement, backward movement, rightward movement, and leftward movement by using joystick as supervision driving and steering control. The geared DC Motors is used as actuators and H-Bridges as motor drivers. Result of driving system shows an error of 3.48 % and braking system is still not perfect enough in maintaining the static position of the wheelchair. The improvement of driving and braking system will increase the performance of the wheelchair.
