Alejo Restrepo

I'm an undergraduate at ETH Zürich studying Electrical Engineering. I love everything around robotics and am always tackling a full-stack project in order to gain as much technical expertise as possible.

Currently, I am exploring robot learning, training VLAs and Video-Action models on custom-built robotic setups, with both parallel grippers and humanoid hands.

When I'm not working on projects I play football, guitar, pick up a new language, or intern at cool robotics startups.
