Yeah, kind of. Currently it only has two BLDC hub motors on the front of the trolley. Someone should try moving them to the back (for better steering), or mounting all four of them and cabling them (mounting brackets are machined and ready). With four wheels attached, the cart __really__ doesn't want to turn, so it might require sanding down threads on some of the wheel to make them perma-drift. | Yeah, kind of.

You can ride in it but please wear a safety helmet. We're not responsible for any damage to yourself or property. When in doubt, __don't__ ride it. | You can ride in it but please wear a safety helmet. You can and will damage yourself and property when the thing gets out of control (it will). You've been warned.

There's currently one hoverboard controller driving two wheels. The rack chassis mounted underneath the basked has two controllers and two batteries, but one is unused. They can be removed when/if we decide that having two wheels is enough. | There's currently one hoverboard controller driving two wheels.

There's a joystick with [[https://code.hackerspace.pl/q3k/freeshipping-controller/|custom firmware]] running on it to send UART commands to the controller. This should be replaced with a real control bus (CAN?) for safety. We can then also add a speedometer, battery and fault indicators, etc. | There's a joystick with [[https://code.hackerspace.pl/q3k/freeshipping-controller/|custom firmware]] running on it to send UART commands to the controller.
