Shield bot Design
I just received my two shield bots that will be used in my classrooms, they are nicely made and and have a nice layout. My suggestion is with the tires. On both of my bots, the wheels are falling off. While the 3d printing is a neat feature, even with the splined axle they are not staying on. Everytime I pick one up and turn it to its side, one or more will fall off. I am not sure why you have the expansion cut in the hub, but I can not see a lot of customers escpecially using this with students keeping them or a long time. I am going to put a drop of glue on mine for the short term.
Thank you a nice suggestion for our product. we are adjust this tolerance in the bore on tires
