Toilet Paper Chase And Indoor Cycling Race With Unity And Arduino

While we’re still far away from returning to a pre-Corona everyday life, people seem to have accepted that toilet paper will neither magically cease to exist, nor become our new global currency. But back at the height of its madness, like most of us, [Jelle Vermandere] found himself in front of empty shelves, and the solution seemed obvious to him: creating a lifelike toilet paper chasing game in hopes to distract the competition.

Using Unity, [Jelle] created a game world of an empty supermarket, with the goal to chase after distribution tubes and collect toilet paper packs into a virtual cart. Inspired by the Wii Wheel, he imitated a shopping cart handle built from — as it appears — a sunshade pole that holds an Arduino and accelerometer in a 3D-printed case as game controller. For an even more realistic feel, he added a sound sensor to the controller, and competing carts to the game, which can be pushed out of the way by simply yelling loud enough. You can witness all of this delightful absurdity in his build video after the break.

But that’s not all. With the toilet paper situation sorted out, [Jelle] found himself in a different dilemma: a cloud foiled his plans of going for a bicycle ride. In the same manner, he ended up building a cycling racing game, once again with Unity and Arduino. From a 3D-scanned model of himself and his bicycle, to automatically generating tracks on the fly and teaching an AI to ride a bike, [Jelle] clearly doesn’t joke around while he’s joking around.

However, the best part about the game has to be the controller, which is his actual bicycle. Using a magnetic door sensor to detect the speed, and a potentiometer mounted with an obscure Lego construction to the handlebar, it’s at least on par with the shopping cart handle — but judge for yourself in another build video, also attached after the break. The only thing missing now is to level up the difficulty by powering the Arduino with the bicycle itself.
