VR Mario Kart Go-Kart

A go-kart I am building with friends that turns a physical track into a multiplayer Mario Kart-style game. We welded the frame ourselves, are using electric motors and batteries for the drivetrain, and drive with VR headsets on a predefined track. Virtual coins make the kart speed up; getting hit by a shell slows it down. The aim is to make the digital race affect the real vehicle immediately without losing the feel of driving a go-kart.

Synchronize multiplayer game events, virtual track position, and physical motor output quickly enough that the effects feel immediate while keeping the karts safe and controllable.

• Speed changes triggered by the game must stay inside a safe physical envelope
• The virtual track and real predefined track need to remain aligned in VR
• Multiple karts need consistent, low-latency shared game state
• The welded frame, batteries, motors, brakes, and controls must work as one reliable vehicle

• Build the frame in-house by welding it ourselves
• Use an electric drivetrain so software can command controlled speed changes
• Map coins and shell hits to bounded motor-speed changes rather than purely visual effects
• Use a fixed physical track so the VR course can be aligned and tested repeatedly

1. 01

   Weld and verify the frame geometry

2. 02

   Integrate the electric motors, battery system, braking, and controls

3. 03

   Define and align the physical and VR versions of the track

4. 04

   Connect multiplayer pickups and hits to the kart's speed controller
