Disabled or senior citizens living alone in security complexes have to carry their groceries from the parking area to their home, one item at a time. I am busy building a shopping cart that follows you. People have suggested I use SLAM, your thoughts?

Why not just a motorised shopping cart with the added bonus it would act like a powered walking frame?

That is the whole idea, but remember a wheelchair user needs both hands and some people use walkers. My end product or dream is the user carries a two button remote on his car keys, on an off, on and he rides with his wheelchair and the cart follows. Speed is determined by the distance sensor. Does it make sense or am I on the wrong track.

Wheelchair users can have a carry bag attachment?
A walking frame can be attached to a motorised trolley.
The bottom line here is there is no cheap solution.
In another thread, which I can't locate, I suggested one of the follow me golf carts which could be modified to carry other things.
I don't really know the situation you are referencing but can the motorised trolley be shared to make it more cost effective?

I think it was mine
The new Jetbot software is shaping up just fine, and I thought I'd ask if you'd looked at the Jetbot as a solution
The Feather Wing Motor controller that the software is written for only handles 1.2A per bridge (2 motors, left and right), but, if you're only going to have something that's not huge, that might be enough for you, and the software is already written, although I haven't tested the "follow me" part of the program yet, so I can't attest to how well that (most important piece for you) works, but, as soon as I finish taking 200 pictures, the follow me is going to be the next part I test

Please try and visualize this, a friend of my stays in a security complex, she parks under a carport approximately 30 meters from her house, she has to get her groceries from the carport to the house but she can only carry one item at a time. The pathways are all paved, nothing complicated, so all along the path to her house it's level, if there are people walking on the path they will give way to her or you stop.
Have a look at the attached clip, extra features will be added later

The video shows the way I built my robot base out of wood!
And how accurate is the gps for taking the robot into a building?
It requires the user have a android phone for the follow me function.
What is not shown is what the base does if it hits an unexpected object?
I guess the pathway could be stored as a series of gps points?
Ok so your project is for one person?
I notice the use of 3d printer is required make a hub adaptor and motor mounts and swivel wheel mount.
