Mobile Eccentric Droid (MobED)
No pricing yet… it comes from Boston Dynamics of course (who else makes packhorses?)
It can go up to 30 kph, which for me means there is an obvious use that is not mentioned. It can trundle along behind your bicycle or electric scooter.
It looks nimble but it does weigh 50kg. The battery is big enough for it to operate for up to 4 hours.
