Velox moves through water and across sand, pebbles, snow, ice, and other surfaces, performing tasks robots designed for only land or water cannot. Its undulating soft fins, inspired by stingrays and millipedes, allow this versatility. Originally designed to generate electricity from rivers, the fins resist debris and impact with obstacles like tree trunks

I'm not sure if the humanoids operate autonomously (perhaps they are simply controlled remotely from a console), but the level of cyberpunkiness is still off the charts!
