If you visited the @uwcherryblossom.bsky.social, did you “spot” an unusual visitor among the blooms? Researchers in the @uofwa.bsky.social #UWAllen #robotics group recently took advantage of some nice weather to take our Boston Dynamics robot dog for a stroll around campus. #AI 1/5
Thank you! Yea we also went through a lot of the papers that tried to do long range perception for the LAGR project. Really cool to take inspiration from works almost 20 years old but still very relevant :)
This project was a fun effort with Matt Schmittle, Nathan Hatch, Rosario Scalise, @mateoguaman.bsky.social, Sidharth Talia, @khimya.bsky.social, @siddhss5.bsky.social and Byron Boots. 🧵6/6
This work is a collaboration between the Personal Robotics Lab (@siddhss5.bsky.social) and Robot Learning Lab at the University of Washington @uwrobotics.bsky.social @uwcse.bsky.social 🧵5/6
🤖 Real-world tested: LRN cuts down interventions on Spot and a large tracked vehicle. ✅ Plug & play: Works with nearly any local stack that accepts goal waypoints. 🔄 Auto-labeled: Trained from raw FPV videos using CoTracker to trace camera paths. 🧵4/6
🔥 Key insight: Robots can reason further by learning to identify distant affordable frontiers as intermediate goals. 🧠 How it works: It uses a pre-trained SAM2 backbone + small head to find frontiers in images. Given a goal, it selects the highest-scoring one to navigate to. 🧵3/6
❗️Problem: Robots navigating with no prior maps relying only on local sensors have a limited mapping range (due to sparse/noisy depth) causing myopic decisions. 🧵2/6
