Field notes from UBR — what was tested, what broke, and what gets tested next.https://ubrobotics.ai/enhttps://ubrobotics.ai/field-notes/robot-drives-back-to-what-it-remembers/https://ubrobotics.ai/field-notes/robot-drives-back-to-what-it-remembers/Eighteen hours of ordinary missions left behind a map of 60 named places. Then we picked the robot up, put it down somewhere else, and told it to go back to the drone.Sat, 08 Aug 2026 00:00:00 GMThttps://ubrobotics.ai/field-notes/selected-nvidia-open-models-codefest/https://ubrobotics.ai/field-notes/selected-nvidia-open-models-codefest/One of fifteen teams selected for NVIDIA's Open Models Codefest. The number we most want to move is a closed-loop test that reached the goal zero times out of four — and the question we had to correct in our own application before anyone else could.Fri, 07 Aug 2026 00:00:00 GMThttps://ubrobotics.ai/field-notes/black-box-robot-that-noticed/https://ubrobotics.ai/field-notes/black-box-robot-that-noticed/Our robot now keeps a flight recorder — continuous video and audio on its own disk — and notices things by itself: a person at 14:02, a voice in an empty corridor, labelled and indexed while nobody was at the console.Tue, 04 Aug 2026 00:00:00 GMThttps://ubrobotics.ai/field-notes/three-weeks-bench-to-field/https://ubrobotics.ai/field-notes/three-weeks-bench-to-field/The field brain grew senses it can verify, survived reality's curriculum, and now navigates space it has never seen — with every mistake published alongside the results.Tue, 04 Aug 2026 00:00:00 GMThttps://ubrobotics.ai/field-notes/nvidia-open-models-codefest/https://ubrobotics.ai/field-notes/nvidia-open-models-codefest/Fifteen teams, NVIDIA's open models, and one question we can't answer on our own hardware: which model gives a machine the best judgement inside the power budget of something that has to carry its own brain.Wed, 15 Jul 2026 00:00:00 GMThttps://ubrobotics.ai/field-notes/house-painting-prep-paint-platform/https://ubrobotics.ai/field-notes/house-painting-prep-paint-platform/Repainting a house is mostly the dirty, dangerous prep — not the paint. So we don't build a paint robot. We build one access platform that carries swappable heads. Here it climbs a rope up the wall, washes, and sands. Drag it around; swap the head.Tue, 30 Jun 2026 00:00:00 GMThttps://ubrobotics.ai/field-notes/solar-cleaner-wiper-bar/https://ubrobotics.ai/field-notes/solar-cleaner-wiper-bar/A rain-fed brush that lives on your rooftop array and keeps it clean — no technician, no roof penetration, no operator. The low-fidelity design model we're taking into our first site visit.
