Making a Robot Chainsaw. Carving dogs.

Check out for 50% off your first month of any crate!

When I was offered the chance to beta test a forthcoming robotic arm from Tormach, I knew what exactly I desired to do with it. CNC chainsaws baybeeeeee. Aside from being basically epic, 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!

  1. Stuff Made Here

    Hope you enjoy this robot as much as I do 🙂. A big thanks to everyone who helps to make these projects possible through their patreon support. If you’d like to help me make more projects like this (and get more behind the scenes content, an AWESOME discord, livestreams, etc) check out

    • My dad makes them nicer and cheaper then the one u showed so if u want info my Insta is @in_the_treestand

    • Absoutely Awesome there Big Fella…. Cant wait for the ‘Fine Tuned’ version…..

    • BlackSheep Speed and Fab

      Your intelligence is amazing, so you prolly already knew this, but a ripping blade would help you a lot. Most of your cuts are with the grain.

    • #11 on trending my BOIIII!!!!

    • You could use something like PhysX to simplify the mesh to a set number of faces say around 60 or so, then with each face generate a rectangle around it that would be safe for the place to entirely cut through then move the blade through the length of the rectangle, it would require a lot of linear algebra but should be simple enough, cheers!

    Thank you for calling it a “CNC machine” instead of just a “CNC”. It soothes my ear.

  3. I trust you, you are a ingeneer..

  4. Every day he inches closer to becoming our Tony Stark.

  5. Look like tesla dog

  6. Simulated Annealing, maybe?

  7. *20 seconds in*

    me: “oh this seems dangerous, neat!”

  8. You blow my mind every time you upload

  9. I know just enough programming and can infer just enough engineering to know the insane amount of work something like this takes. Extremely impressive. With all of these wide ranging projects that take so much soup to nuts end to end engineering (software, hardware, CNC, welding, calibration, design, etc.) it’s almost a shame it’s just for like our entertainment. I feel like you should be figuring out how to core into an asteroid and blow it up with a nuclear detonation to stop it from entering the amosphere. But, entertain us by annoying your wife seems like a good second place.

  10. Instead of using gradient descent, use BFGS or differential evolution in python lmfit package
