With industrial robots we initially think of an Automated Guided Vehicle (AGV) and these have specific battery requirements. Also, this field is rapidly changing with industrial robots with their own unique battery requirements.

Boston Dynamics Spot Battery
Boston Dynamics are very frugal with the data they release about their products and especially about the battery packs. However, we thought it would be good to see what we can find.
This will also give us another reference point for the sizing of battery packs for industrial robots.

Robot Battery Swap
The UBTECH Robotics Walker S2 robot battery swap demonstrates a robot that can operate indefinitely.
75kg humanoid robot has an average power demand of ~1.5kW with a peak of 2.5kW
