my cousin has MS and uses an electric wheel chair when he's at home. I was talking to his brother today an I guess he's not the best navigator at the house and his walls are showing the pain.
I'd like to surprise him with an obstacle avoidance feature when i go home for the holidays.
my plan is to use some ultrasonic sensors. 4 total, one on each cornerhttps://www.adafruit.com/products/981
and possibly simple interface to toggle the system on and off.
the chair is an invacare Pronto M61 w/Sure Step & Standard Pwr. Elev. Seat
the joystick looks like this:
I'm searching the classifieds for a used one that i can test out here in cali so it'll be pretty plug and play when i go home.
my goals are:
be able to turn the system off
im not sure the best way to accomplish this. Would it be best to hack the donor controller, cut the traces of the joystick and put the arduino in line with that?
thanks for the help
