How does it not vacuum up tons of pebbles and sand at the same time?
- lifestyleguru 2y agoThis is probably EU innovation funds at work. Still impressing that they assembled something resembling a functional prototype, and not only gigabytes of PDFs and DOCXs.
- geor9e 2y agoThat's probably why they never show it on sand - it would suck it up. Things with the highest surface-to-mass ratio would make it to the top of the vertical tubes — things like dust, cigarette butts, and candy wrappers. Pebbles have too low of a surface-to-mass ratio to get sucked all the way up the vertical tube.

(Sand depletion is a concern in many areas.). Robo-dog could return to a dock which automates part of that separation process. Then return the sand to the same spot. Cleaning might be a concern (spreading spores of invasive species) if used in different areas.
