My favorite part of the Sprout launch video is when he demonstrates soft compliance of the robot by lifting his little leg.
Tells me they're perhaps the first ones to implement soft compliance in a humanoid product, similar to FACET, SoftMimic, etc.
Overall, the policies demonstrated, even though the behavior was basic, impressed me even more than the robot (though it is a very cuddly robot)
Sprout was designed with safety at its core.
If robots are going to exist closer to people, safety has to shape the entire system. It has to inform the materials we choose and the way our robot moves and responds in shared spaces.
