Ant Group's Robbyant Open-Sources LingBot-Map, Turning Ordinary Phone Videos Into 3D Point Clouds on a Local GPU

Robbyant, the embodied-AI unit of Ant Group, has released LingBot-Map, an open-source foundation model that reconstructs walkable 3D scenes in real time from ordinary smartphone footage, running locally on a single consumer GPU. The model, published under the permissive Apache 2.0 license, takes a streaming video feed and produces both a point cloud and an estimated camera trajectory in a single feed-forward pass, without the heavy optimization loops that have long constrained earlier reconstruction pipelines.
