Power management remains a critical hurdle for humanoid robot developers. Agility Robotics Inc. announced a collaboration with Nyobolt to develop a rapid-recharge battery system for its Digit 5 platform. According to both companies, this innovation enables the robot to operate for over 20 hours daily.

“For our clients, maximizing Digit’s uptime is the core business case,” said Daniel Diez, Agility’s chief business officer. “Digit 5 delivers more than 20 hours of productive work within a 24-hour cycle, effectively covering two full shifts. This gain significantly enhances the value customers derive from Digit and improves the economics of deploying humanoid robot fleets. Nyobolt’s ultra-fast charging technology makes this possible, serving as a key component in making Digit 5 ready for large-scale operations.”

Since its founding in 2015, Agility has positioned Digit as “the first multi-purpose, human-centric robot that is ‘Made for Work’ and commercially deployed today.” The Salem, Oregon-based firm reported accumulating over 65,000 real-world operations. Last month, it unveiled Digit 5 with updated legs and acknowledged exploring wheeled locomotion options.

Nyobolt develops batteries for rapid charging

Established in 2019, Nyobolt states it has integrated proprietary anode materials, advanced battery cell design, and integrated power electronics to achieve fast charging, high power density, reduced weight, and extended lifecycles. The Cambridge, U.K.-based company claims its technology supports demanding industrial applications and minimizes downtime—a major constraint in robot utilization.

Nyobolt notes that its patent portfolio and global presence support AI data centers, physical AI, and mobility applications while lowering total cost of ownership. In May 2026, the company reached a $1 billion valuation after raising $60 million, including investment from Symbotic Inc.

“Nyobolt’s technology was selected because Digit 5 requires more power from a smaller, lighter pack in environments where reliability is non-negotiable,” said Sai Shivareddy, co-founder and CEO of Nyobolt. “Agility set an exceptionally high standard for battery durability in live warehouse and manufacturing settings, and this partnership demonstrates what is achievable when ultra-fast charging is engineered for the most demanding conditions in physical AI.”

Digit 5 offers extended runtime for humanoid users

Agility describes Digit 5 as its first humanoid robot designed to operate safely alongside people at scale. It features a new battery system providing 90 minutes of runtime with a charge time of just nine minutes. This 10:1 run-to-charge ratio marks a significant improvement over Digit 4’s 2:1 ratio.

The company asserts this capability allows Digit 5 customers to target longer operating windows, more productive shifts, and more complex task sequences. Agility states that this battery performance, combined with its commercial deployment experience, strengthens Digit’s value proposition for warehouse, distribution, and manufacturing operations.

Agility anticipates early access to Digit 5 equipped with Nyobolt’s technology will begin in the first half of 2027. Availability will expand over the subsequent six to nine months, the company added.

Agility executives prepare for merger and speak at RoboBusiness

Agility plans to go public via a merger with special-purpose acquisition company (SPAC) Churchill Capital Corp XI. In July, the company opened a software and capabilities hub in Fremont, California, to accelerate physical AI development.

Earlier this month, Agility partnered with FORT Robotics (also pursuing a SPAC deal) to advance robot safety. Additionally, Agility CEO Peggy Johnson joined Project Meridian, a U.S. Department of War initiative exploring the future of warfare and informing long-term investment priorities.

At RoboBusiness 2026 next week in Santa Clara, California, Jonathan Hurst, Agility’s co-founder and chief robot officer, will participate in the opening keynote on “The Next 20 Years of Robotics.” On Day 2, Pras Velagapudi, Agility’s chief technology officer, will join a keynote panel on the “State of Humanoids.” Register now to attend.
