Anyone see Wreck-it Ralph? I have been working on Sergeant Calhoun’s hoverboard from the movie.
Inspired by a probably-joking comment from my BF that it should be motorized, it’s now motorized. I don’t have a great pic of the setup, but in this image, you can see the two scooter wheels set up in the middle-back. The casters in the front keep me from falling over entirely and there is also one behind on the tail.
Arduino Uno powered by a 9v. Controls are via a wii nunchuck hooked into ports A0, A1, ground, power. Dual VNH5019 shield attached to 2 Razor E200 motors (200 Watt Motor, 24 Volt, 2750 RPM, 11 Amps) and a standard 24v scooter setup (2x 12v 10AH lead acid batteries in series). With the board, wheels, motors and batteries, i’m guessing weight is around 40 lb. Motor/wheel setup inspired by a guy who made a self balancing skateboard using the two motors, wheels, batteries and a sabertooth controller. i went with pololu for the reputation (a friend of mine said you guys were an excellent company, and i’m, admittedly, an electronics noob, but an eager and fast learner) and the fact i found a controller that works for my purposes half the price of the sabertooth.
I am getting motor faults. I managed to test drive my hoverboard around without me on it, and it worked fine (well, relatively. i have some steering tweaks to make as it’s not as responsive as i’d like). When I myself, tried to ride on it though (bringing weight to 200 or so) it moves, then seems to stop after 10 feet. I hooked up my laptop and set it on the board and it’s giving me motor faults (mostly 1, but sometimes 2). I’ve attached my arduino code.
A friend of mine, who helped me setup the wiring and such on it thinks maybe that i’m not giving the motors enough amps (the batteries power both) and so when i get on the board myself, it panics. I’m able to reset everything (don’t have a specific system for resets, yet) to get the motors to go again when i flip it over, but it’s a consistently sporadic and inconsistent problem. heh.
Would adding a second set of batteries fix the issue? If so, would I have to upgrade my controller?
