DIY quadruped robot (various surfaces)

3d printed quadruped robot driven by hobby servos, li-Ion batteries, a teensy and gyroscope. Remote controlled via bluetooth.
(new code can handle carpet)

This is the most impressive servo-driven quadruped I've seen. Its movement is quite close to Boston Dynamics' dogs. And it looks like it could be very agile with the right control algorithms.

smart putting the servos in towards the shoulders as much as possible as this lowers the moment of inertia and thus strains the motors less and probably makes stepping quite a bit quicker

[victorjung]

I have to agree with the other comments, it's incredible work for hobby's servo ans single person work !!!! Congrats!

[qnaman]

As for single person work vs billion dollars company - it's excellet work. It looks and behave almost identical like dog mini by Boston dynamic.

OMFG...what a cute little thing!!!

Will you make the files avaliable for other people to build it? Please??? ^^

Three letters OMG it looks like the boston dynamiks one. Very impressive!!! I saw down in the comments that a lot of people were talking about James Bruton. His robot dogs are not as impressive and I dont think they work properly. I think he should focus more on the speed of his robots. This is why they keep falling over and over. There are olso heavy which is olso a factor that causes the robot to be unable to lift its own weight. Excuse me for my english. Its because I am not a native speaker. I am from Greece

WOW!! this is awesome, this is absolutely the best homemade robot ever seen!
seems very well mechanicaly designed. Automation on that just blows my mind.

[AxisSage]

this is so much better than the robot dog/mini robot dog series! Thanks youtube for finally giving me a good recommendation.

Great job! I'm currently reengineering the legs of mine in a way similar to your robot. The closer the motors to the axes of rotation, the faster they can be moved since they have less inertia.

[Ezio-Auditore]

I can't tell if the marching in place movement is part of the walking algorithm or an imitation of the BD's robots. Amazing work.

[caner]

Martin is a genius in reverse engineering guys..we should applause and respect.

[isaac]

That's looking really fantastic! I can't wait to see more, keep up the great work!

"Mom, can I have B o s t o n D y n a m i c s?"
"We have BD at home."
BD at home:

Jokes aside: really nice job!

Boston Dynamics Called: They want Spot's puppy back!
IMPRESSIVE WORK!

[Keksstar]

@James Bruton - look, it´s finished :D

[rahulr]

Man these seems like a miniature version of Boston dynamics..
Would love to build one.. can I have the 3d images file? For printing the parts

[myetis]

great job,
for some dampening and become more flexible mechanics, you would put a strong spring throughout rods of servos which manipulate the elbows
it will bear some load with reduced servo stress.

[alexandersergeev]

Awesome work! As I understand, this is only a beginning. But so impressive beginning!

[alexyurich]

Это идеальное воплощение одомашненого псоРобота!
Тазобедренный сустав компенсированный!
Отличный подход. Код проекта нужно изучить

[Sketchy_Dood]

what a cute lil thing, it looks like it's excited to be there
