Hello, I'm a software engineer experienced in robotic perception looking for a job in the field in Seattle area. I plan to move there from Denver this summer....
I seriously doubt you'll find anything like this. By the time you're ready for a case, every project is different enough to make the chances of selling enough...
Dan ... OK but it's not like a standard photovore which measures the relative light levels on the left and right. Imagine that each fresnel lens is like a...

Peter Surely a non scanning PIR on a robot creeping towards you is exactly the same as you creeping towards a non scanning stationary PIR operating your...
Alan ... In the demo of hexapod pirouetting (hexapod.exe), I'm changing the complete trajectory of the feet. I work out where the body and the supporting ...

... Alan, do you mean translate laterally like a crab? Horses definitely walk laterally. It's called a sidepass. Found you several pictures and videos: ...
Hi Peter, I just realized that I've been thinking mostly of a circular layout of legs on a hexapod. That's what I have implemented. And I'm realizing that an...
Hi Robin, Thanks for the URLs. I hadn't thought about horses moving in that manner. I know a little about cattle, and how they move, but I haven't much...
... They can "cross-over" their front legs ok, ie, move towards the inside while also twisting the spine, but aren't as good at moving the feet to the outside....
... Minor variation on a Braitenberg type-1 vehicle. Wife-field sensors rather than narrow-field. ... Yeah, I was just doing orientation/detection, not...
... I favor your scenario over Peters. :) ... I wish I knew. Supposedly, frogs can only see moving objects [or at least they only "respond" to such]....
Figured this job might interest someone. Its in Virginia with a pay range of 85-100K. It requires a lot of robotics experience but I'm not looking for work...

... Ummm, I think inline hex would do a fine translation, as long as you have 3-jointed legs with the leg-body connection servo having a vertical rotation...
... From what I can tell, cats either "slink" which is really a form of creep, one leg at a time, with the body held really low, or else they do a full tilt...
Hi Dan, A cat would be hard to duplicate! I've watched our cats, they are wonderfully agile. Ours can even simple "rise up" on their hind feet when they feel...
Hi Dan, I'd forgotten about using TWO joysticks! Although I like a single joystick. ... That should work. I like the "motion vector", as it should be a...
... "cross-over their front legs" means the front of the body is supported over a leg. "moving the feet to the outside" means the front of the body is not...
Cats practice their moves until they have them down. If you change things even slightly, they will goof up until they've done it enough to get it down again. ...
Alan ... I really don't think you can resolve it that way. For a hex, I think you simply consider where the CoG is relative to the supporting trianqle; where...

well, I really need videos of the various slow gaits. The creep-gait looks most interesting. I'm just going to have to get more proficient (and patient) with...
Good observations. We have seemingly have a pair of meercats as well! They are incredibly fast running around the house, and up and down the stairs. How to...
... Hi Alan, Well, I guess what I was suggesting is that you could set up (or borrow or rent) something like an exercise wheel with a video camera positioned...
Hi Peter, ... Doesn't seem to be too bad from my limited work. ... That would be interesting to see. But more complicated? ... Might be. Floating point...
Hi Robin, Oh I get it! Yes, a wheel might give me what I need. I certainly can't keep up with the two young cats! I don't know what all my JVC video recorder...
Hi Alan, Your camcorder almost certainly includes video editing software you can use to view separate frames. If not, though, there are tons of freeware...
Get/make one of those big exercise wheels as shown in those videos or a treadmill. For going up & down the stairs, you might have a chance if you could mount...
