When comes to lower part it’s always bipedal (hard to balance) or wheels (low capabilities).
Why no one makes 4-6 legs, insect like?
That seems like an easier problem to solve while gives much better mobility.

- throw310822 3mo agoA couple hundred legs would be optimal.
- 05 3mo agoThey make robot dogs, e.g. famously Boston Dynamics but many others as well. And 6 is probably overkill for price/performance increase incremental to 4. Wheels are still much more practical and you can use them as feet in hybrid designs to be able to step over obstacles but still more agile than comparable bi/quadrupeds
- solid_fuel 3mo agoGoing from 2 to 4 legs doubles the amount of actuators required and substantially increases power consumption since you must move more mass, going to 6 compounds the problem further. In a future where we have more dense power storage and better (and cheaper!) motors, you probably will see robots with more legs. But for now, the most efficient solutions are bipedal. Especially because this thing is already $8k, I imagine they have already done some substantial price optimization.
- bensyverson 3mo agoReal question: what about 3 legs? Is tripedal locomotion a viable compromise?
- levocardia 3mo agoReal answer: how many animals can you think of with three legs?
- bensyverson 3mo agoAh, so it’s impossible to make a robot unless it looks like an animal
- scotty79 3mo agoKangooroos?
- pphysch 3mo agoThere are millions or billions of quadrupeds surviving on 3 legs every day. 4 legs is evolutionarily superior to 3 but 3 gets the job done, especially if you don't have to worry about agility or repair.

- wat10000 3mo agoHow many animals have wheels? And yet wheels are a pretty practical choice for a lot of things.
- scotty79 3mo agoIf the robot has two legs with wheels at the ends it could combine speed and flexibility. Adding a third leg for additional stability when the robot needs it might be great. But the third leg would probably need to be between the first two and I don't think humans are mature enough to have that.
- shaewest 3mo agoI wonder how much of it is training data. We can very easily get training data of 'human tasks' because humans can wear tracking suits, and those suits track bipedal movement. Anything we train off that isn't bipedal (ie dogs) don't do human tasks, don't hold anything, so a different set of requirements.

- jonfw 3mo agowheels are so much simpler that it seems much easier and more cost efficient to solve the "transporting a wheeled robot up the stairs problem" than it does to go fully bipedal.
