Your Living Room Becomes Next Mario Kart Course

RomoCart, Indoor Robot Racing

[Ken] likes his living room and he is on a continual mission to make it more interesting. Recently, he has made a giant leap forward with a racing game project he calls RomoCart. Think of it as a partially-physical game of Mario Kart. You are able to race others around a track while still having the ability to fire projectiles or drop defensive measures in efforts to win the race!

First, lets talk about the hardware required. The racers are standard Romo educational robots. Wireless game controllers provide the means for the drivers to control the Romos. Hanging from the ceiling is an Xtion motion sensing camera and a video projector, both pointed down at the floor.

To get started, the system scans the floor and determines a race course based on the room layout and any physical objects in the vicinity. A course is then generated to avoid the obstacles and is projected onto the floor. At this point it would still be a pretty neat project but [Ken] went way further. The ceiling-mounted camera tracks the motion of the Romos driving around the track and the video projector displays a smoke trail behind each racer. Randomly displayed on the track are items to help you win the race, including an acceleration item that makes your Romo go twice as fast for a short time.

Have a tailgater? No problem, just pick up some bananas and drop them on the track. If a following competitor drives into one, they spin out. If you want to get super rude, pick up some missiles and fire them at the racers ahead of you. A direct hit will stop them right in their tracks.

[Ken] is no stranger to HaD, he’s had a few of his projects covered here before. Check out his Tempescope, Moving Window and his Autonomous Lighting System.

Check out a video of the racing in action after the break. It is amazing!

Real life Mario Karts react to launchable items

real-life-mario-kart

The team over at Waterloo Labs reasserts their reputation for creativity with this real life Mario Kart project. One of the team members must work at Austin’s Park because they seem to have had free rein when it comes to modifying the go-karts and filming the delightful video presentation found after the break.

It’s one thing to put on some costumes and head off to the go-kart track. It’s another to modify the vehicles to react to items launched by another rider. You can see the painted PVC launcher hardware to the right of each driver. By stuffing a plush item (banana, star, mushroom, etc.) in the barrel the driver can use compressed air to launch it quite a distance. Inside of each item is an RFID tag. When the RFID reader on a kart detects the tag it can take control of the steering, brake pedal, or speed limiter to inflict the appropriate actions.

If you don’t have this kind of insider access to your local go-kart track don’t fret. You just need to build your own set of karts.
