Inspired by the cliff-racing trials of Jubmachia, this challenge is all about speed, control, and distance. Using a rubber band–powered car, your team will design a vehicle that can launch from a raised edge, transition smoothly from rolling to gliding, and land as far away as possible without crashing or tumbling. The best designs balance propulsion, stability, and aerodynamics. Distance matters, but control matters more. A fast car that spins out or nose-dives won’t go far. Fine-tune your wheels, wings, weight distribution, and launch angle to achieve the smoothest, longest drop. Think fast. Build smart. Stick the landing.

In Jubmachia, robots must stay fast and functional even when the ground is shaking. This challenge puts your bot to the test on a vibrating raceway that simulates seismic tremors. Using simple materials, your team will design and build a small robot that moves forward as quickly as possible while the track vibrates beneath it. Some designs will spin, stall, or drift backward, only well-engineered bots will convert vibration into reliable motion. Experiment with balance, friction, contact points, and weight distribution to turn chaos into speed. When the ground won’t stop shaking, smart engineering makes all the difference.

In Jubmachia, speed and precision rule every contest. In this challenge, your team will build a nitrogen-powered top that spins at 20,000 rpm to battle in a compact arena. The goal is to stay in the arena and knock your opponents out. Only bots engineered for stability and power will claim victory, so think fast, build smart, and spin to win.

In Jubmachia, speed isn’t just physical, it’s mathematical. In this DESMOS animation challenge, use equations, inequalities, and polygons to create a dynamic scene involving a vehicle race. Will you animate a car race or something more futuristic ? Use math to bring the action to life; precision and creativity are your keys to win !
Students should complete and submit their creations one week prior to May's event, or sooner

In this high-stakes investigation, teams must decipher encrypted files, uncover hidden schematics, and piece together a trail of cryptic clues surrounding a top-secret experimental vehicle. Combining online challenges with layered puzzles and coded messages, this immersive scenario tests logic, teamwork, and sharp observation. Every recovered fragment brings you closer, but the full picture remains hidden. Will your team uncover the truth before it disappears into the shadows?

In Jubmachia, precision and speed can save lives. In this challenge, teams will design and build a robot capable of carefully retrieving a hazardous object from a tricky location. Using simple materials and smart engineering, your bot must navigate obstacles, grip securely, and transport its cargo safely. Only the most balanced, controlled, and efficient designs will succeed, think fast, build smart, and retrieve with precision.
Students may need to complete in advance - We'll discuss with participating schools regarding feasibility.
