they were pretty dominant in a lot of sectors. AutoDesk products pre-cloud produced large files (well, they still do, but transport is no longer an issue.) -- so zip drives were pretty ubiquitous in design until CD-R.
They actually describe it as "6+1 degrees of freedom" [1] with the gripper being the "+1" - so it's got base, shoulder, elbow, wrist1, wrist2, wrist3, and gripper.
This is a conventional way of describing things. Traditionally robot arms come with a "tool flange" where you attach your own "end effector" (which might be a gripper, or a suction cup, or a welding gun, or a paint sprayer, or whatever) and we count the degrees of freedom before the tool flange separately from those after the tool flange.
Occasionally robots come with 7 degrees of freedom [2] which gives you more options for reaching the same tool flange position. This can be useful in certain applications, like working around obstacles in the environment. It's uncommon though.
It should be noted that 6 degrees of freedom is the minimum that enables reaching any point with any orientation of the effector, while 7 degrees of freedom is what a human arm has with the shoulder fixed, which enables reaching some points even around some obstacles that would block a 6 degrees of freedom arm.
Including the movements of the shoulder, a human arm has 9 degrees of freedom, but the additional 2 degrees of freedom do not provide a new capability, they just extend the range of possible motions beyond that limited by the joints of the other degrees of freedom.
An arm with many degrees of freedom, like an octopus arm, could reach some places even when having to avoid many obstacles.
His point is that the robot has split the kinematics to have 3 DOF for position near the base and 3 orientation DOF on the wrist.
This still gives you 6 DOF on the end effector, which is pretty good, but overall the arm design is restricted in its ability to route around obstacles.
This downside has an upside though. Since every cartesian position has exactly one pose for the first 3 DOF, the inverse kinematics are simpler and you do not run into singularities for basic position control when maintaining a constant orientation.
I'm sorry, I was confused. This arm appear to have wrist pitch and yaw "backwards" from standard split forearm configuration, and I mistook the wrist yaw motor to be something else.
Although, it does still worry me that there don't seem to be a lot of footage of this arm with that axis away from its neutral position...
>If I'm applying for a work visa where the work I'm doing would require me to know Japanese, I should know Japanese.
the naturalization act of 1906 and the immigration act of 1917 , in the US, were some of the hardest fought-for and controversial laws ever put in place.
The immigration act got vetod by 3 different sitting presidents in different forms , and the naturalization act included a 'free white persons & natives' clause that screwed over a lot of people.
It was pretty widely seen as a method to minimize poor working people. Both laws were used a ton during the commie red scare against citizens, and the 1917 law is essentially held responsible for the separation of families / 'port of entry tragedies' that separated families based on things like language.
now : i'm not saying that Japan is walking in the same foot-steps, just pointing out that language/culture exclusivity within legal spheres usually ends poorly for the people.
Without knowing the numbers, I'd wager that the majority of work Visas worldwide are "dual-intent", to use the USCIS parlance. Restrictions might be higher or lower in different countries, but there's generaly a path dor moving from a work visa to permanent residency.
I think we need to acknowledge that all but the most transitory fruit pickers may want to settle permanently after working in a country for many years, and should not unreasonably be prevented from doing so.
If i were working in a country for many years, I would make some effort to learn to communicate with the other people who live in that country, before becoming a permanent resident. I understand this is very difficult; I've been studying Spanish every day for almost 2 years and I am nowhere near fluent. However, I suspect I would be further along if I lived somewhere where people commonly spoke Spanish.
There is nothing unreasonable about if you want to live in a country you should learn the language. I said in another comment that I’m learning Spanish now because I plan to move to a Spanish speaking country for retirement.
realistically any 'huge' frontier model that takes a rack of H100s to infer against is probably going to have downtime no matter who runs it.
downtime is always going to 'scale' poorly against loads that require a lot of hardware thrown at them, even with lots of good fail-over -- probably worse for the small vendors because they don't have the contracts supplying them with hardware first so availability is already at a premium for them.
so, I guess i'm saying yeah I hope frontier-level-models get out soon in the open arenas, but I suspect the same or similar level of exclusivity will exist as long as they take that much compute to operate.
