Engineering the underground.
An ETH Zürich student team designing and building micro tunnel boring machines.
Groundhog Gamma.
8.6 meters long, 60.8 cm across. Designed, machined and assembled by students.
Four subsystems.
One machine.
Each small team of students works on its own subsystem, but in the end, everything needs to come together and work as a whole.
Every part, accounted for.
Built in-house or carefully sourced, every component is modelled and checked before the machine ever goes underground.
Faster, more precise tunnels for the water, power and data lines cities run on.
Founded in 2020, more than 200 students from twelve countries design, manufacture and operate every machine themselves, then take it underground to compete.
