The link to the CAD files seems to be broken.

The board that was sent to me, has the damaged socket at the ends, for example pin d12 of the nano without connection to the board. another problem is the soldering of the components, practically desoldering components, apparently the assembly work done by trainee. I was disappointed with the quality of the product.

What is the dimension? 20 x 20 ?

We purchased this robot and other things on Jsumo, we are very satisfied, very quick answers by email to solve our problems and we received the package in just 2 days, great job !

It is usual to receive an ebb right away after payment and this is why I am going to an electronic format rather than hard copy. I ordered mine this morning but still waiting for it, could you find a faster way to receive them ? Thank you

hss material really good.....

The motor was powerful for sumo robot, but you will need bigger wheels since this motor has square mount that is hard to be mounted into low-profile frame without overhang the small wheels. You should use > 50mm wheels for this motor. Too bad that JSumo Team didn't response to any emails, messages or chat that I sent regarding the use of this motor, i.e: Can it handle overvoltages to 15v or 24v ? Can it operate on Magnetic sumo robot?
