Gyroscopic Bipeds: A Different Way of Walking with Dr Pauline Pounds

[@stevenborham1584]

Saw a film a while back that demonstrated that birds don't use inner ear balance organ as much as the lumbosacral organ. Perhaps Pauline is approaching bipedal balance more the way Avians do by starting with the flight ready balance in drones/quadcopters and not thinking balance relative to a head or CPU/location.

I thought of trying to get a toy kit of this exact idea in like 2008. 3D printers were expensive and there were some but not a large assortment of well documented microcontroler / SBC solutions for non-electronic engineers. And everybody I tried to wrangle in hated it. I think its very practical and really smooths out the edges. They must have genuinely hated it because no one stole it obviously. 15 years later and only now do we have neural net based bipedal robots and BDI bots still fall a lot.

I once sat next to Eric Laithwaite at a dinner when a student at Imperial College.

I remember watching him at Royal Institutes Christmas Lecture on BBC years ago. At the time he stated he was the only scientist in the world studying gyroscopes. It had a massive influence on me as I still remember it ? years later

i would really like to know where to buy a CMG with enough mass to do this.

[@sandorrabe5745]

How much did all of this cost?

[@1crazypj]

$4240 Australian dollars, around 35 minutes into vid. I think they got ripped off for the machining as there should be a 'tool room' quality lathe in the engineering department at university. Machine shops can get expensive real quick. In the 1990's I worked for a company that was paying machine shop £170.00 an hour (approx $350 US at the time) They had the equipment to do the job at the place I was working, just no one to run it (until I came along)

[@anthonyrepetto3474]

Gorgeous innovations, thank you! I imagine this would work really, really well for small *SALTO-bots* who seem to have trouble sticking the landing... if the salto-bot could deploy a glide-wing, then perch on a telephone wire? ...it'd be better than the quadcopter-salto-design, which seems a bit power-hungry in comparison. Have you considered dual, opposing gyros, as well? You could stack vertically, or adjacent in a few configurations... a pair of smaller gyros would also leave a spot for a crewmember's pod :O

[@ulforcemegamon3094]

There is a robot called "Gyrobot" that does that , it uses four gyros and some of the gyros can oppose other gyros in order to get rid of the parasitic torque , is also way bigger than this one and more stable

Australians are more casual with that than any other English speaking nation so far as I've observed, compared with Americans, Brits, Kiwis, South Africans, Canadians. Be an adult and just ignore it.

[@erikrodriguez7112]

If we are here to learn, and this is a formal education class, why were social political elements included in this? They serve no purpose and have no function in the topic of discussion, unless the intent is to include them into the content, in which case makes them even more inappropriate in this context. This is a topic on robotics, engineering, intellectual pursuits. So why were things such as gender, transgender, gay, and so on included? How do those topic apply to the given topic of this class? Or are we simply politicizing this class with non relevant social political garbage?

[@1crazypj]

Sounds like they got ripped off on the machining, plenty of hobby machinists and machines can make things to micron tolerances. I used to do PRODUCTION machining to 3 micron tolerance (0.003mm) If I fitted new bearings to my cheap Chinese lathe I could probably still do it although it would take longer than the two minutes twelve seconds job allowance when I was 19

[@dekutree64]

That's about how it was when I looked into getting parts machined a few years ago. For the cost of a couple small jobs, you can build your own machine and make hundreds of parts, with the freedom to iterate on the design rather than fretting over whether it's perfect because the one shot costs half your total project budget. There's really no other option if you're doing to do robotics R&D work.

[@thewheelieguy]

.05mm (or as an American I can better relate to .002") is not precision machining -- I wonder if she ought to have put another zero or two and simply misspoke. There was an error on the slide with the mass of a cricket ball where it said 0.156g and as she'd said the weight was "about 150 grams" it should have been kilograms.
