The robot arm I used:
Please consider supporting these projects through my patreon:
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!

    • 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.

    • do you think it's possible to make a machine or system of machines that will grow you the perfect plant? like look at it and determine what it needs and then give it to it? control sunlight, water, minerals, etc.

  • This is a perfect example of how the robot's productivity gains get eaten up by the amount of programming time. Even manufacturing at factories tends to utilize more than one process to get to the end product.

  • In particolare, il costante supporto informativo e propagandistico delle nostre attivita risolve in modo inequivocabile la necessita di esperimenti che colpiscono per scala e grandezza. Prima di tutto, la teoria esistente rivela un'urgente necessita di rafforzare i valori morali. La teoria esistente, cosi come un nuovo sguardo alle cose familiari, apre certamente nuovi orizzonti per i compiti fissati dalla societa. Conclusioni banali ma inconfutabili, cosi come prototipi interattivi sono solo un metodo di partecipazione politica e sono stati oggetto di tutta una serie di studi indipendenti.. A experiencia rica e diversificada nos diz que o pensamento racional, diluido em uma boa dose de empatia, exige que analisemos o sistema participativo! O ponto de vista oposto implica que os defensores do totalitarismo na ciencia sejam descritos com o maximo de detalhes possivel. Por outro lado, elevar o nivel de consciencia civica oferece amplas oportunidades para decisoes conceituais autossuficientes e externamente dependentes. Os defensores do totalitarismo na ciencia, superando a dificil situacao economica atual, estao unidos em grupos inteiros de sua propria especie.

  • Your chain saw is overheating do to lack of lubrication. Also not professing to be an expert at robotics, but where j work he have huge fixtures mounted on robots and you just have to tell the robot where the new tool center point is wether it is 6 foot off the arm or 6 inches, the robot will move accordingly to that point.

  • Have you considered using an air motor for the saw? This should help offload weight from the saw. Also I don't know enough about your workflow here to say for sure, but I know most robot control software allows you to define tools, which could help prevent the "why are you hitting yourself" issue

  • wow you sure pick some big hard projects! I admire you perseverance! Also I think you need to file down the anti kickback tooth a bit and maybe sharpen the chainsaw if it doesn't cut wood...

  • 17:17 ........Those parts in front of the cutting tooth are called rakers and they need to be progressively shortened as the cutter is filed since the cutter is angled and gets shorter as it is filed .......Time to sharpen the saw basically ................

  • luv your channel... luv your style... got an idea for you, make an arm that can throw the worlds fastest and perfect dart game. Stipulations: its got to function like a human arm e.g. it pivots at an "elbow" and at the "wrist". A preloaded magazine is allowed to hold the proper number of darts. Trying to decide if full 360 degree rotational movement at the "elbow" is allowed or it is to move forward, release dart and then return to a start position ( < 180 degree arc)... The full 360 rotational movement would be the faster but setting up the electrical would be harsh unless the control signal was wifi or bluetooth. The main power could run off of a slip ring/contact brush, but as mentioned, the signal for the controls.... hmmmm ;) ...

  • 🤦‍♂️That is a raker; not an anti kickback tooth🙄Tour robot is pushing the saw into the wood. You do not force the cut. You let the saw cut at the speed it wants to. It will not cut faster if you press harder. Normally that wood just kill the engine. If your motor is powerful enough to keep going you are just creating heat and eventually the chain will snap.

  • 😂I love your presentation. I have thousands of hours of Chainsaw time. The reason chainsaw art is so impressive is the amount of tip cutting involved which is a slightly dangerous and difficult to master endeavor especially if your upper body fitness is a disaster. You can carve up a piece of wood in reasonable amounts of time with a combination of slabbing and then tip cutting. Beware of fatigued stability muscles, loose chains, dull chains, dirty logs, hardwoods, and especially be very cautious of old chains, kickback, and flying chunks of wood which will surprise you with a whack to the face at some point.

  • As someone who uses a chainsaw on a daily basis, I must comment, that it's clear that your trying to push a dull butter knife through a piece of wood. In other words, it's dull. The second you put on a new, or freshly sharpened chain, you will see a world of difference. If you don't know how to sharpen it, you should probably take it to a shop, where they generally charge $9 to $12 per chain. Also, in on of the shots, the chain was loose. It must have the proper tension, and be Sharp.

  • The funny thing is that you didn't even bother to ask someone who uses chainsaws whether or not a pole saw could cut a log. Obviously you figured out the answer, it can't! A pole saw is meant for small branches. Heck, it probably even says that in the manual, which you always brag about not reading. :)

  • So... honest question here... Why didn't you iterate off of the pumpkin carving setup for this machine? I know it's not as cool as chainsaws - but you'd have the potential for some amazing functional 3d CNC work that could push the community forward (especially if you're willing to open-source your work) and also provide you with some very unique patents (which you could use to ensure that the community doesn't get bulldozed by some company that wants to own sole rights to this kind of tech.) I love your content, and expanding it beyond casual youtube shenanigans to create/evolve the industry would be mind-blowing.

  • Not an engineer, but am a chainsaw wielder. I think the problem you were having with the wood is a combination of not having the proper chain/bar combo for carving, the chain not being properly sharpened, and not having enough RPMs to cut through it. Solution: Better bar/chain, a good file, and a stronger motor pulling at 12k RPMs.
