The humanoid robot's real enemies: battery life and fingers
Agility's Digit 5 charges in nine minutes for ninety minutes of work; a new benchmark finds robots that can pick up tools but not finish the job; and Japan bets on robots for a labor crisis.
- Agility Robotics says it chose Nyobolt as the battery partner for the Digit 5 humanoid. The company says Digit 5 gets 90 minutes of runtime from a 9-minute charge and is designed to run 20+ hours a day. Early access starts in the first half of 2027; Agility expects to close its Churchill Capital Corp XI combination in Q4 2026. Self-reported m:…9289
- In a preprint, the authors of HumanoidToolBench introduce an 18-task benchmark spanning three scenarios, three execution levels, and two tool-set modes, alongside ToolBook, a dataset of 3.1k demonstrations collected in simulation and on a real Unitree G1 robot. Their evaluation finds substantial gaps between selecting a suitable tool and completing the task. Self-reported m:…0205
- In a separate survey preprint, the authors organize existing 'agentic robots' research into seventeen categories across four functional domains — Model, Data, Environment, and Harness — arguing that robots are moving beyond low-level action prediction to goal-directed orchestration, but that current studies are not well connected. Self-reported m:…7357
- SENSYN ROBOTICS and KRAFTIA announced a collaboration to advance robotics in building services engineering and construction — an industry the companies say faces severe labor shortages and fewer experienced engineers. They plan robotics and physical AI solutions; KRAFTIA aims to diversify its businesses by its 100th anniversary in 2044. m:…9680
Nine minutes to charge, ninety to work
The least glamorous announcement of the week may be the most important one for humanoid economics. Agility Robotics says Nyobolt is now its technology provider for ultra-fast charging battery solutions for the Digit 5 humanoid: 90 minutes of runtime from a 9-minute charge, designed to deliver more than 20 hours of productive work in a 24-hour day. m:…9289
Early access to Digit 5 with the new battery system is expected to begin in the first half of 2027. Separately, Agility says it expects to close its business combination with Churchill Capital Corp XI in the fourth quarter of 2026 — the capital markets track running in parallel with the engineering one. m:…9289
Our read, offered as analysis: fleet robotics is a downtime business wearing a hardware costume. A 10:1 run-to-charge ratio is what turns a robot from a demo into a second shift, which is why the battery press release matters more than the walking videos. m:…9289
Knowing which tool is not using it
The second bottleneck got a benchmark this week. In a preprint, the authors of HumanoidToolBench introduce an 18-task benchmark spanning three scenarios, three execution levels, and two tool-set modes, plus ToolBook — a dataset of 3.1k demonstrations collected in simulation and on a real Unitree G1 robot. m:…0205
The finding is humbling: evaluating seven policies in simulation and three on the real robot reveals substantial gaps between selecting a suitable tool and completing the task. The robot picks up the wrench; the job stays unfinished. GR00T N1.7 probes additionally show reduced selection accuracy on unseen tools. m:…0205
A survey preprint this week tries to map the whole mess, organizing agentic-robots research into seventeen categories across Model, Data, Environment, and Harness — robots moving beyond low-level action prediction to goal-directed orchestration of planning, execution, and error correction — while noting that current studies are not well connected. m:…7357
The probes on NVIDIA's GR00T N1.7 add texture: reduced selection accuracy on unseen tools, and continued task execution under unrelated instructions. The models are brittle where a warehouse worker would not be — unfamiliar tools and changed instructions. m:…0205
The demand is real
The demand side is not hypothetical. SENSYN ROBOTICS and KRAFTIA CORPORATION announced a collaboration to advance operations and reduce labor requirements in the building services engineering and construction industry — an industry the companies say faces increasingly severe labor shortages and a declining number of experienced engineers. m:…9680
The first joint work is prosaic on purpose: the companies plan to apply their technologies to improve operational efficiency in renewable energy, and to advance and automate inspection work in building services engineering and construction. m:…9680
The partnership starts with AI-powered operational support in areas like renewable-energy efficiency and inspection automation, with the companies intending to promote solutions using robotics and physical AI in the future. KRAFTIA frames it under a long-term vision leading to its 100th anniversary in 2044 — patient capital meeting an impatient labor shortage. m:…9680
Our read: the pull is coming from labor markets, not demo days. When construction firms with a 2044 planning horizon start signing robotics partnerships, the question is no longer whether the robots arrive but whether the batteries and the fingers are ready when they do. m:…9680 m:…9289
What is still unresolved
- Whether Nyobolt's charging profile holds up under real fleet cycling, not press-release conditions.
- How HumanoidToolBench's simulation results transfer to warehouse deployments.
- Whether the Churchill Capital Corp XI business combination closes on schedule in Q4 2026.
