Walker’s up to date software program is the results of continued AI coaching on its unique — together with the identical optical sensors throughout its physique, together with 36 high-performance actuators in its limbs. Earlier than the crew might increase the strolling tempo, the main target had been on the robotic’s sense of gravity and naturalness of its strolling movement. Reality be informed, the boosted tempo nonetheless did not fairly match that of a standard human, however I did discover that Walker had much less sideway sway whereas delivering a basketful of snacks to me.

I used to be extra impressed by the robotic’s newfound sturdiness. Final yr, I used to be solely allowed to softly push Walker whereas it was strolling (and the engineers have been noticeably fearful by my enthusiasm), however this time, Ubtech allowed me to push the machine with nice pressure whereas it was stationary. I did not go excessive, however I might undoubtedly really feel how Walker resisted with counteraction by its legs, so it will have been onerous to topple it.

Primarily based on the identical precept, Walker’s arms might raise extra weight than earlier than, even when one aspect was heavier than the opposite. In a video demo, Walker was seen carrying a 10kg load on his left wrist and a lighter six-kilogram load on the suitable with no drawback. When the demonstrator eliminated every load individually, Walker barely moved.

Such improved steadiness additionally allowed Walker to drag off some primary “yoga” poses for me to comply with. I say “yoga” as a result of these have been clearly not actual yoga poses, as confirmed by a yoga-instructor pal of mine. The closest one was the single-leg, forward-reaching pose that considerably resembled the start of a half-moon pose. Technicalities apart, I used to be impressed by how far Walker has come by way of dynamic self-balancing, and whereas I struggled to maintain up with it, I did recognize the tai chi-like circulation between poses.

One other key improve this time is Walker’s enhanced environmental notion by means of visible servoing. In a nutshell, the robotic was utilizing visible knowledge to trace small objects and thus dynamically alter hand actions and grip to work together correctly.

Through the demo, Walker confirmed off this explicit talent by steadily pushing a cart out, choosing up a basket and writing the Engadget emblem with a marker. Regardless of my earlier torturing, Walker was nonetheless prepared to pour a bottle of Coke right into a glass for me (an enormous improve from passing me a can of Coke final yr), and I used to be impressed by the way it gripped onto the glass till it was certain that I used to be taking it off its hand.


These new upgrades could look like child steps, however they’re important to enabling service robots to really service us in our houses. After all, Walker has but to display extra potential abilities, particularly on the human-interaction aspect in addition to finer actions right down to the extent of digits. It is no marvel why Ubtech mentioned we’re nonetheless a way away from with the ability to carry a Walker dwelling, however that would nicely occur in a couple of years. If you have not already, it is about time you begin saving up to your robotic pal.
