Construction/Contracting AI RL Environment (Crane Lift Demo & Unreal Engine)
The slides and full script for this video
A tower crane has one job: set the last steel beam on the top floor. On its first try in this construction RL environment, built in Unreal Engine, the beam lands on the frame. After practice, it goes straight into place with zero hits. What this video covers: what a crane lift costs a contractor, why a construction company would build its own private RL environment, why AI labs want construction data such as lift logs, site plans and CAD files, how a reward function scores each lift, what a 2025 study found, and what happens to your data when you license it. The job site is a demo built for...
