Don't know the motor length :(

These wheels are amazing for the cost. I only have one issue with them: The set screw (or maybe the included Allen key?) strips really easily and I can't properly tighten them onto the axel.

Can you pass me the datasheet?? pls

Робот может ли проехать если толщина линии 5 см

is this motor real???? can use in robot sumo 3kg?

I received two XS1 robots last week - I am very impressed with the engineering and build quality. It is great fun to prepare them for battle, easy to use out of the box and easy to program using Arduino IDE. JSUMO Service is very kind and responsive. Thanks for making a great product!

one of the best boards I recommend it to anyone who who wants to win

What are the specifications of the battery suitable for this motor, and is it possible to find them available to you?

Hi, is it able to change to follow black line instead? Admin reply: Robot actually follows BOTH black and white line at sametime. Smart code understands transitions and works at both surfaces.

We bought the Shogun Mini Sumo Robot and we were pleasantly surprised with its quality and weight.. The wheels are better than expected and it grips good with brass motor bracket. 9/10!
