Hi 221B Baker Street,
I have considered that and it seems to only take up the same amount of distance as your car door opens at its widest, so if you can open your car door right up then you have enough room for it to operate.
The only thing is that if somebody else comes along and parks after the previous person you may get stuck if they park too close to you.
I suppose it does limit a bit in that instance however if you have shoulder issues you need to add up the pros and cons.
The R11 robot can load flat folding chairs into a variety of car boots as they get turned sideways when loaded.
