hi guys, im designing a mini wheelchair controlled by PIC18F452...
this are the requirements:
1. it's a mini wheelchair ... enough to fit a barbie dol
2. the direction of the wheelchair will be remote controlled.
3. the wheelchair has to avoid obstacles by turnining to another direction
so, i actually have a rough idea on how to do it .. but i dont know how correct it is .. this is wat i think ..
i use a joystick to control the direction of the wheelchair using IR telemetry .. the signal from the joystick will be transmitted to the PIC and the PIC send instruciton to move to motor of the wheelchair.
my question is ..
wat kind of motors do i need and how do i make it bi-directional ??
wat does the IR telemetry consist of and how does it work??
i was told that an amplifier is needed for the motor .. why is it ??
the wheelchair avoids obstacles in front of it .. i think by using a sensor ... wat sensors do i use ??
can anyone help me ??
