Berlin just hosted the best robotics meetup in Europe. 🦾 We wanted to get 50 friends together. 500 people applied once we put a private page up. The demos were all made in Europe: a fully autonomous electric tractor that lifts 4 tons (Voltrac). A multi-ton autonomous excavator (sensmore). Drones built fully in Europe (HIGHCAT). Anti-drone lasers (Stealth). Strike systems delivered by balloon (Planetfall). A payload that sees landmines through soil (Sapper Intelligence). Multiple robot arms working perfectly in sync (EVASIVE ROBOTICS). Satellite defense lasers (also Stealth). Actual Star Wars stuff. The reason we do this is simple. If these tractors, robots, lasers aren't developed and produced in Europe, they'll be built elsewhere. We need these jobs here. These manufacturing sites here. And the best way to get more founders building them is to show what's already possible and inspire the next ones. Next stops: Today in Athens (join us here, link 👇), soon in Munich and London. If you want to host one, hit us up. This is CLANKERS by PROTOTYPE. For Europe. 🇪🇺🔥

We decided to organize a meetup around agentic coding last week. We're talking about it non-stop at @BuildMonumental, we've been doing internal sessions to learn from each other, so why not invite a couple others as an experiment?

"That's taken us like a couple of years now to build that trust. And I think we're getting much, much better at it." @sfvisser , @BuildMonumental explains: "You're an outsider. You're doing the very weird trick on a site that is totally not used to it." "If they see an actual wall being developed by a robot or like several robots at the same time in different segments and someone's just standing next to it like this and not interacting at all, that is very magical."
A couple weeks ago, we ran our first 24h non-stop build with our robots at @BuildMonumental (maybe in the world?), running for 36 hours straight to do the brickwork for a transformer substation.

"People love robotics in general. It's just a fun topic. It's just Legos for Grownups." @sfvisser, breaks down the type of talent him and @salar attract at @BuildMonumental: "One thing that's fun for me is that almost everyone is bought into the mission of fixing the housing crisis. It's a very easy story, right? Very easy mission." "We're really looking for people who understand this through all the layers, who are willing to see a very technical problem and get messy, get dirty, collect data, then back into the office and fix it."

Niall, one of our first hardware engineers, just wrote an amazing post about his journey, on dropping out of his Masters (highly recommended for many talented people!) and joining @BuildMonumental in the first very months of being founded.

If you're into hardware, there is probably no team more exciting to join today than Monumental's hardware team. We're hiring Mechanical, Mechatronics, and Electrical Engineers (besides many other roles!) monumental.co/jobs

I wrote up how this works in practice, with examples from our production system: buildmonumental.substack.com…

On a single construction site, we now have up to 30 AGV platforms operating in parallel, each carrying a custom construction robot.

Once your robotics fleet grows beyond a certain point, coordination quietly turns from a hardware problem into a software problem.
