Test configuration
Independently measured
G1 EDU-4, Dex3-1 three-finger hands, firmware 1.04
Fraunhofer identifies the tested configuration and states that the unit was delivered in May 2025; results should not be generalized to other variants or firmware versions without qualification.

Energy and endurance
Independently measured
239 W mean power and 1:49 h derived per-charge endurance in the defined typical scenario
Fraunhofer measures power in standardized standing and walking conditions and derives maximum operating times from those results. The 1:49 figure is not presented as an observed continuous field run or cumulative runtime. Fraunhofer also reports 154 W standing, 272 W level walking, 283 W at 10% incline and a derived 2:49 h for standing only.

Walking speed
Independently measured
0.49 m/s slow and 0.84 m/s fast walking measured with 3D tracking
A 3 kg load did not reduce steady walking speed in the described test, but increased acceleration and deceleration time by several tenths of a second.

Thermal constraint
Independently measured
Outstretched arms could shut down after one to two minutes without added payload
Fraunhofer attributes the shutdown and dropping arms to actuator overheating. No frequency across repeated trials or recovery time is published.

Collision force
Independently measured
Mean peak forces of approximately 510 N at the chest and 530 N at the abdomen in specified walking collisions
Fraunhofer's public safety guide states that displayed values are mean peak forces from at least three trials per scenario with the robot in fast mode at about 1 m/s. It does not publish the underlying observations, spread or unit-to-unit variation.

Stability and recovery
Independently measured
No balance loss on cable-channel steps or a 20% ramp; recovery depended on floor friction
Self-stabilization was strong in the described tests, while standing up from the back failed on smooth tile and wood because the arms could slip.

Cybersecurity
Independently measured
Bluetooth remote-code-execution vulnerability found in the tested software state
Fraunhofer reports that the vulnerability persisted across several firmware updates and was subsequently closed by a newer update.

Delivered autonomy
Independently measured
Remote-controlled walking available after delivery; further capabilities require user implementation
This is the observed baseline of the tested EDU configuration, not a claim about every later software stack built on the platform.
