How long does a humanoid robot work before it has to charge? Agility Robotics says its Digit 5 runs for 90 minutes on a battery that charges in 9 minutes, enough for more than 20 hours of work in a 24-hour day (September 15, 2026). Uptime is published as well: Humanoid reports more than 8 hours of uptime for its robot in a logistics test at Siemens' electronics factory in Erlangen (April 16, 2026). This page sets out the uptime and charging figures makers have published for named sites, and reads them against a shift.
The published figures at a glance
| Site or robot | What the maker published | Source |
|---|---|---|
| Siemens electronics factory, Erlangen (test) | Uptime of more than 8 hours; 60 tote moves an hour; autonomous pick-and-place success above 90% | Humanoid, April 16, 2026 |
| Digit 5 (specification) | A 90-minute run on a battery that charges in 9 minutes; more than 20 hours of work in a 24-hour day | Agility Robotics, September 15, 2026 |
| Digit 4, customer sites in North America | More than 65,000 hours of operation in nearly three years of commercial deployment | Agility Robotics, September 15, 2026 |
| BMW Group Plant Spartanburg | 10-hour shifts, Monday to Friday, for 11 months; more than 1,250 hours of runtime | Figure, November 19, 2025 |
Erlangen: three numbers from one test
Humanoid tested its HMND 01 Alpha in logistics at Siemens' electronics factory in Erlangen, where the robot moved totes. Humanoid says the robot met all of the test's target metrics, and it published three of them: 60 tote moves an hour, uptime of more than 8 hours, and autonomous pick-and-place success above 90% (April 16, 2026).
The uptime decides whether one robot holds the station through a shift or a second one takes over while the first charges.
Digit 5: a short charge after a short run
Agility Robotics published the specification of Digit 5 on September 15, 2026: a battery that runs for 90 minutes and charges in 9, for more than 20 hours of work in a 24-hour day.
A charge cycle like that shapes the station plan differently from a long run. The robot leaves the station for short, regular breaks through the day, so the work waiting for it has to hold for those minutes, and the charger has to sit close enough to the station for the walk to stay short.
Hours at customer sites
Agility says its Digit 4 humanoids have logged more than 65,000 hours of operation across customer sites in North America, including GXO, Schaeffler, Amazon and Toyota Motor Manufacturing Canada, after nearly three years of commercial deployment (September 15, 2026). At GXO's Flowery Branch facility near Atlanta, it reports a cumulative 100,000 totes at about 98% accuracy while on task.
Ten-hour shifts at a car plant
Figure reports that its Figure 02 deployment at BMW Group Plant Spartanburg ran 10-hour shifts, Monday to Friday, for 11 months, and logged more than 1,250 hours of runtime (November 19, 2025).
Four questions behind an uptime figure
When a maker quotes an uptime figure for a pilot on your floor, four questions tie it to your shift.
- What counts as uptime: the hours the robot was at the station and able to work, or the hours it was working.
- Where charging happens: at the station, at a charger the robot walks to, or by a battery swap.
- What happens after a stop: whether the robot recovers on its own or a person restarts it, and how long that takes.
- What the robot does while it waits for work, since a station that runs dry lowers the count with no fault in the robot.
Reading uptime against your own shift
An operations adviser asked on LinkedIn in September whether customer pilots track completed work per shift, including charging and recovery time, since that makes the benefit easier to compare with an existing workflow. The figures above give that comparison its units: moves an hour, hours of uptime, hours of operation and shifts worked.
At your own station, uptime is counted the way work is counted there today. Keep a log of the hours the robot works and the hours it charges, and note every stop that needs a person to restart it. Set beside the station's current rate and your shift pattern, that log shows whether one robot covers the shift or two share it.
In a Consultation, we set the rate and the uptime for one station on your floor against your own shift pattern.
