About MexspireX
MexspireX asks every team to pick a real problem, build a robot or machine that tackles it, and explain how it works to a jury. It rewards what good STEM teaching is for: curiosity, teamwork, and the patience to make something actually work.
A working robot, machine or automated model, built by the team.
Sensors, logic and control, from a first circuit to fully autonomous behaviour.
Every member explains their part of the build to the jury.
Categories & theme
This year's theme is "Machines that Make a Difference". Every MexspireX project starts with a real problem. Build a robot, a machine or an automated system that solves part of it, then show the jury how it works.
Helper Bots
Pick one small, everyday problem and build a machine that helps with it. It can be simple: what matters is that it moves, it works, and your team can explain how.
Project ideas
Smart & Sustainable Cities
Choose a problem your city faces, such as waste, water, traffic, energy or safety, and build a robot or automated system that tackles part of it. Show the sensor input, the decision and the action.
Project ideas
Autonomous Systems for Real Problems
Design and build an autonomous or semi-autonomous system for a real problem. The jury will look for sound engineering, a clear control logic, and evidence that you tested it.

Judging
Every team presents its project and answers questions. Scores are weighted towards a build that actually works, and a team that understands it.
Does it do what the team says it does, reliably, on the day?
How original is the approach to the problem?
How clearly does the project address its category theme?
Can every member explain their part with confidence?
How well does the team handle questions about its design choices?
