When I was offered the opportunity to beta test an upcoming robotic arm from Tormach, I knew exactly what I wanted to do with it. CNC chainsaws baybeeeeee. Aside from being fundamentally awesome, it is a very interesting software problem. Since I didn't have to build the arm I was able to focus the project and the video on the software challenges of making something like this work. Thank goodness I didn't have to build the arm because the software almost killed me. I can imagine all kinds of next steps for this creation like machining textures with the chainsaw or cutting topiaries. I hope you like it!

Hey, you should try an offset grinder with the chainsaw blade. You could probably do more intricate cuts. Just a thought. I could NEVER figure out how to do all that you did.

Your videos are awesome! Idea: Mirroring programming While the saw is attached to the arm, have a zero point. Have a professional carver carve something while the arm records the movements. Once they are done, save the the program. Now, every time you place the log and robot arm at zero, you can just run that program... would be awesome! Mass produce famous carvers works at a fraction of the price.

You can also wire yourself up so that if you touch the saw you close a circuit which kills the saw. This is used in bench saws. Maybe it can be done capacitatively, so if you come to close to the saw its capacitance will increase and this can trigger it to stop

Here's an idea. The divine combo of carbon and silicon. Use your setup to manually chip away at the log, restricting your movements with your software model. Ok, maybe clunky unless the robot isn't really flexible. How about this: use a laser to "color" the log where it needs chipping until a dog is all that remains. (Is that a thing? I feel it should be. There is no way no one has thought of it.)

@Stuff made here, just an idea for using the estop when your in the kill zone. We use a double deadman switch for programing our material handlers. Ours are built into our tech pendants but it wouldn't be hard to make a stand alone one. Basically it's a switch that you hold half way down in order for the robot to move. If something happens and you release the switch it kills the arm and if something scares you and you tense up and push the button further down it'll also kill the arm. It's a pretty safe system. We also use cameras and stuff so that when you are in the work cell or kill zone the robot will only run at half speed. Then once you are outside the kill zone you don't need to hold down the deadman to the halfway position anymore and it returns to full speed.

Dude, thank you for explaining this to me in a way that I actually understand. I was talking to a friend of mine recently (I'm 28) and we were agreeing that we, pretty much, learned not much of actual worth, in all our years of high school (in the UK). Teaching in the UK is no where near as good as what it should be, and I think it comes down to the teachers themselves. Not one that I can remember, looked interested in the subject they were teaching... From your videos, and your explanations, I learn more than I did while at school. Through you, and others like you in other subjects, I'm filling the holes in my education. Cheers. Love from Scotland.

This comment turns out to become a joke on me. I was trying to figure out what music you were listening to during your programming session around 14:35 (upper screen). And then you change of scene at time 14:42 and I saw your screen with a new page... There, my mind flipped and I thought you were looking at a page with the title: "Why are Dog's Wiener so Long?" It took me five minutes to realized that I am the one with twisted ideas... Well... my bad. So... what music were you listening to by time 14:35? :) :)

You should use this robot arm to your hair cutting robot And please add upward moving comb in front of suction cup it will allow to cut correct length of hair One more suggestion in front of suction cup don't use that metal sheet use a sensor over there we need comfortable working LOVE YOUR WORK ❤️

Software optimization means _not_ using Python.. Dunno what it is about you and CodeBullet, but y'all are just stuck in the false-peak that is an interpreted/JIT language. Move to a compiled language, many many orders of magnitude faster, even for terrible code.

For the gradient ascent problem, you just make multiple guesses and check if each result is the same peak. Then just pick the highest value found.

I don't know why youtube does not want me to watch this channel. I have subscribed and unsubscribed 4 times. Turn the notification bell off and back on 6 times and I still do not get notifications when you post a video. It's only this channel that does this to me. So I am forced to check back every 4-6 weeks if I can remember and see if there is anything new posted.

baianoise Day ago
In my rumble opinion your project would have taken greater advantage of a 5 axis CNC machine (the robot arm plus the rotating table should have actually even more degrees of freedom), it's just that instead of a chainsaw the arm should use an endmill and the coordinates should be totally different, fortunately mathematically it should be possible to apply a linear transformation in the robot arm + rotating table to transform the system in a 5 axis CNC, if there is someone who are specialist in those arms and details, please let us know, thanks for the video !

Get a pro chain, one with no kick back. one that’s fresh or one that has been professionally sharpened is preferable. Also you need lube for the chain. The other option is to grind down the guide teeth down but just to below the cutting teeth.

I would transition to using a laser. That would improve the chainsaw mobility problem. The downside is your kill radius increases and gets other flavours like a blinding radius.

For whenever or never you will make dog from a log you miss two key things... Lubrication to the chain (that is why it was heating) and different chainsaw bar shape. It is funny how we always try to predict all small details and forget something major (still can't believe you tried to cut wood without oil).
Kamala Nenavath

Stephen Cervantes
Hey why don’t you turn the saw vertically. That’s how lots of the cuts are made when humans do chainsaw log art ? It would solve issues for getting into those tight spaces you have when the saw blade is turned horizontally. Like maybe you start horizontal get off the bulk then rotate for the detail .. let me know if you think this is a good idea ! :)

Hi! One very common way to overcome the non-global maximum search is to add simulated annealing, it follows the same principle as the annealing of metals by adding some randomness to the calculation of the gradient descent (or ascent, it depends on how you pose your problem) in such a way that some times the optimizer makes a decision against what would be optimum locally. en.wikipedia.org/wiki/Simulated_annealing

MrJacobegg Day ago
With as many comments as this has, I'm guessing you won't see those but, in the off chance you do: look into Particle Swarm Optimization to help with your problem of getting stuck in local maxima. PSO will sample tens to thousands of points from your vector space, in a single run, then moves all of those points around in the problem space for some configurable period of time, eventually converging around the collective swarm memory of the lowest (or highest) point observed by any member of the swarm. This helps avoid the problem of tunnel vision from sampling a single point in each run, as with gradient descent. You can also combine PSO with gradient descent (or ascent) to get the best of both worlds.
