Absurd!

You do not understand? This arm is the rebellion of the machines, it is the beginning of the T-800 😯

🤣😂😂🤣😂

Lmafo couldn't have said it better

That's exactly what I want to say too! You're closing up the Judgement day. And machines will rise. Everething is predicted. Now the arm is ready. It least a little bit for everithing else. Of course it's a joke. Or...? Anyway you work looks great!

Best comment ever

The source of the problems was the new principles chip in his hand, but here you can only rely on a couple of sensors. So there is still a place to move)

🤣

You would need medical grade platinum silocone in order to pull that off but it does last for 45yrs

😆👍

oh... that's easy! - a wife and two kids and your mind is blown up! 🤣

Yes, I spent quite a long time developing a method to do that!

There's a lot you can do on a manual mill with a digital readout that many people assume you need a CNC for. The only CNC work in this video is the engraving on the forearm cuff.

Skynet yes the detailed plans are available on the internet to download? the hoing on about chat gpt not that relative do this stuff yet? so where being told its's not up to forwarding the hole of the plans and forwarding them on to Manufacturing companies and getting parts shipped somewhere else final assembly

Actually, coincidentally, Bob is my uncle. 😁

I plan to use a small camera to recognise and track targets... I mean people, not targets at all!

I want to know how he made the model used to make the mold.

I drew them in CAD and then 3D printed them. This is my preferred method now for things I only want to cast one or two of. I used to make patterns from wood which last much longer for repeated use.

No, not the same guy, but I know who you mean, great channel.

@@AndysMachines I love both channels, among others.

Yes, I designed this one, but such things are quite common. The 'nut' is a bit different in my case though.

@@AndysMachines yeah I like the brass drive nut

Thanks! The optical encoder is a quadrature type so it does keep track of position in both directions, though it is an incremental type so yes it does need initialising on power up (for this actuator I'll do this by just running it to a mechanical stop, others may have switches). For some of the other joints such as the elbow I will be using the type of absolute magnetic encoder you recommended, but there wasn't anywhere to mount one in this case.

Thanks for those, I'll check them out...

Thanks, but they're not quite perfect and there's room for improvement. I learnt a lot about metal casting from Olfoundryman on youtube, key things that have helped me are using a pouring basin, tapered sprue and generous feeder when required. Also degassing with argon (welding gas bubbled through a pipe with lots of small holes in it) seems to really help with porosity. I mostly melt down old scrap, but I always include some aluminium that was previously cast, these alloys are normally high in silicon which helps the metal flow better.

Thanks! 👍

Yes, it's an incremental encoder so will need to be homed with either a switch or a mechanical stop. As the screw makes multiple turns a magnetic encoder would also need some reference to set the initial position. I may use absolute encoders mounted directly to the joints in other places and the magnetic ones are a good choice as they are small and quite high resolution.

😉

Yes, aluminium.

Why not it will be fun bro

Do it do it do it do it! I dont think you dare 🐤🐥🐤

Connect it connectttttt .....ittttttt😂😂😂😂😂

It'll either not do anything or go "OH GOD I CAN FEEL" and instantly shut itself off

​@@MaGestic1yeaaahhhh finally found someone interesting

Thanks! Yes, you are correct it is an incremental encoder so will need some way to set it's initial state. On some actuators I will add a switch, on others I will just run them gently to their mechanical stop. I may also use absolute encoders on some of the joints to avoid this problem.

Apparently a T-800 was supposed to weigh 400 pounds (180Kg). I think it will be somewhat less than that.

Thanks! Yes, I try and plan / design things before I start making them, but some parts just need to be made first so I can see how they all fit together. I find a lot of the parts are actually smaller than I imagined them when I come to make them, which makes it harder to fit working parts inside. I did plan to put the motors for the fingers in the forearm but there's really no space left so they will have to go somewhere else now.

Don't know if you have seen this guy's stuff may be worth a look... kzfaq.info/get/bejne/e8WaprN5nrm2mp8.html .... kzfaq.info/get/bejne/hp1jf6mi0r7agoE.html I'd also be curious to pull apart a Blitzway Terminator arm to see what they did kzfaq.info/get/bejne/o6llpbar0beRqoE.html

Yes, I have seen that video, very nicely made! His finger mechanisms actually look very similar to how I've done mine, I'll have to route the tendons at least around the moving elbow though (probably with bowden cables). The blitzway arm looks very nice and the motion is quite fast and realistic. The base it sits on is pretty big and I think there are six servo motors in it, one for the wrist and the fingers are all independent. kzfaq.info/get/bejne/jpNmityIqdWsmYE.htmlsi=JxeBkyzYxrFEKo5e&t=484

Mostly cast aluminium. There's also some stainless steel on the exterior parts. The internal workings are made from various materials, mild steel, brass, even some plastic parts.

Same...

I'd say he's asmith from the looks of it

Thanks! It's called Beside Me by Patrick Patrikios

No, it's not hyperalloy or coltan, the thicker cast parts might withstand a bullet but the rest would take significant damage.
