There is no single AI algorithm available but its a pipeline with many substeps until a robot can do something usefull. Each single step is well understood by computer science in the past and the only thing missing is to combine all the steps into a single pipeline.
The staarting point is usually a teleoperated robot. The movements are converted into numerical sensor information called a mocap recording. Then the motion capture information are converted into a text adventure. This translation step is perhaps the core element in artificial intelligence and has to do with grounded language. After a text adventure is available, the game is solved by a computer program which decides which step is executed next.
None of these substeps can be called advenced computer science. Even the automatical gameplay of text adentures like Zork can be mastered with mainstream software for example with a reinforcement learning algorithm. Also the translation from motion capture recording into a text adventure can't be called a demanding project. Nevertheless the entire pipeline is something new not realized before. A modern term for the entire system is "vision language action model" which is state of the art in robotics in the year 2026.
In general the described pipeline is an abstraction mechanism. It converts a large state space into a small state space. This small state space can be solved with a computer. In the past it was unclear how to do so, and therefor the assumption was the robotics problems are np hard.
