I'm about to start my first major robotics project, making an autonomous cart which will eventually be integrated with RFID passive tags in a factory setting. Since I'm new to robotics, I like the idea of primarily doing stuff that has done before to limit mistakes. My first main problem is the load requirement, 200lbs.
I was told that even if the cart can't quite reach that weight it's okay, but it'd be nice to be in the range. I really like the Arlo system but I see there's a weight cap at 60 lbs. Is it possible to add an extra caster or duplicate the driving wheels to increase the load capacity? Do you have any ideas of how to use Arlo (or another similar model) in a way that comes close to reaching my goal load?
Thanks for any tips!
