[@momonunu]

Is there a way you could upload/do a build guide?

[@ibuildstuff]

@@momonunu sadly, I’m probably not going to make one because not a lot of people would actually have the parts to build it

[@puzzLEGO]

This is seriously impressive stuff! Not only was the editing pretty much on par with a youtuber 100x your size, but the machine itself was super cool! I enjoyed the cinematography with the choices of camera angles and the cinematic at the end was epic! I've subbed to see what else you can come up with on this channel

[@ibuildstuff]

Thank you so much! Really appreciate it!

Boston Dynamics - if you’re reading this, hire this guy. Get him through school and fund him through college. Don’t miss out. Some other company will step in…

[@ericinventor]

Dude this is amazing! So compact and elegant design. We appreciate you showing your failures throughout the process, it gives us all more motivation to power through!

[@ibuildstuff]

Thank you so much!

[@andyrose2723]

This is amazing mate!! Please please please do a tutorial, I know there are thousands of fellow builders out there who’d love to make this. Love that you used Ev3 as well! I made a very basic walking dog years ago but it’s nothing compared to this! Hoping you’ll share a guide or maybe some more detailed photos, the leg mechanics are killer!

[@GermanAviation]

This deserves way more attention, well done!

[@ibuildstuff]

Thanks!

[@UnidudeNine]

Nice work! I know the coding is frustrating at first, but it will help you tremendously on your future projects. I think you should review the math formulas behind Inverse Kinematics and then you'll be set to work on some much more advance robotics!

[@ibuildstuff]

Thank you! And yes, I’ll try learning to do the code for more complex projects in the future!

My Lego Technic Robot Dog was built over 20 years ago, using only what was available in Lego at that time. I did not have any controlling software. Rather I built it to operate by means of gear ratios and carefully timed movement of each moving appendage was controlled only by the way I designed it. Mine had a bobbing head and wagging tail, which helped to keep it on its feet as it walked. It was built as an experiment of torque increasing methods. The entire build worked on just one Lego Technic Motor. I was able to raise the torque to such a strength that it eventually stomped itself to death; coming apart, due to inadequate connection strength between the parts. Some of that was alleviated by using larger parts in place of multiple smaller parts. That said, the connections were never completely immune to the strength of the torque I built into it. It was a very interesting build. I did not have directional changes built in, so it only walked in a relatively straight path. Mine only fell over in my first couple of builds, but after that it only failed when it stomped itself apart. You have access to much better Lego parts than I did, so I would love to see you build more advanced versions of this. Thanks for posting this video.

[@ibuildstuff]

Oh wow, sounds really cool! Thanks for sharing!

[@AzRill5]

I would recommend putting shock absorbers on the feet so that it can balance better. I also saw a return-to-center mechanism for a robot dogs shoulders on the Lego technic subreddit that I feel would be a good addition to this project.

[@ibuildstuff]

Would you mind sending me the link if you have it?

[@sandroalcantara6025]

Send the link plz

[@roddlez]

Nice work! From the thumbnail, I thought this was the Boston Dynamics robot! For turning, have you considered using a motor or servo that makes the body hinge near the center of mass around the vertical axis? Even a slight bend would probably get it turning nicely. Or, if you actuate the hips around the spinal axis, you might even be able to better balance the gait to solve the crashing problem. Just some ideas for future projects...

[@ibuildstuff]

Haha, thank you! I might try improving the steering in the future, thx for the suggestions

[@sqiddster]

Excellent work! I know from experience how difficult it can be to make a sturdy walker with LEGO especially with such a high centre of gravity, well done

Hey, thanks for sharing this awesome build! My son loves EV3 and your robot dog. Did you ever put up a pdf or any other format of instructions for replicating it? Thank you!!!

[@sloanlance]

Why all the indentation on lines 17-19 of main.py at 06:06? Remember, indentation is meaningful to Python, so adding it where unnecessary will cause problems later. If you don't have a good editor to warn you about these problems as you're writing, you'll not know of them until you run the program. If VSCode isn't helping you with this, I recommend IntelliJ IDEA.

[@alex_rivas_art]

Yes I will say in the future that I was here when the channel just have 5 videos. AMAZING JOB. Edit: I check and there was just 4 videos! Just 4! A lot of channels struggle years to reach this cinematic yet funny look.

[@PhoenixClank]

If the front/rear "axles" are always 90° out of phase to each other, why not power both axles with only one motor? Or maybe that's too complicated to get the motion through the entire body. Also this entire time I thought the robot was walking backwards because the elbows and knees are bending the wrong way XD

[@ibuildstuff]

Lol, As you said, it’s too complex to get 1 motor to power both sides and there wouldn’t be enough power

[@CarbonGlassMan]

This is cool. I won my 5th grade science fair in the 1980s by making robot legs where I used a big dual shaft DC motor, then cut wooden circles and beams to make the legs to convert the circular motion into a linear motion going into a human-like walking motion. It didn't walk, but the legs hung off the edge of a table and did the walking motion. This works very similar to the way my project worked.

[@ibuildstuff]

Thats pretty cool thank you for sharing!
