Agility plans nine-minute charging for humanoid robot Digit 5

Agility Robotics will power its next-generation Digit 5 humanoid robot with Nyobolt batteries. According to heise.de, they will provide about 90 minutes of runtime after nine minutes of charging. The company expects that the system will allow the robot to work more than 20 hours a day.
The first deliveries to customers are planned for the first half of 2027.
Work to charge ratio
If you believe the stated figures, the Digit 5 has a operating-time-to-charging-time ratio of 10:1. Digit 4 had a 2:1 ratio, Heise reports. In the old situation, charging consumed about a third of the total time - both working and charging.
Reducing these downtimes is a direct path to higher fleet utilization. Agility claims this will improve robot economics for businesses.
What is known about batteries
Nyobolt batteries are described as lightweight, high power density and resistant to multiple charge cycles. True, the companies did not name the battery life in cycles - and this is an important indicator when frequent charging is built into the operating model itself.
Another way: replacing the battery
Fast charging is not the only path taken by manufacturers of humanoid machines. Heise cites the example of Walker S2 from UBTech: where the robot itself changes a dead battery to a charged one.
Agility's approach builds on something else - shortening charging pauses for Digit 5. After initial deliveries in the first half of 2027, the robot should become more widely available over the next six to nine months, according to Heise.
