How the Robot was Created

This video in less than 5 minutes shows all steps of making the bipedal robot that you have seen in videos on this channel. The steps are:
00:05 Concept Sketch
00:52 Preliminary CAD
01:02 Detailed CAD
01:20 Working Leg
01:37 Assembled Robot
02:18 Ready to Go
03:31 Simulation Attempt
03:45 End Credits
03:58 One More Step
The project was done at Columbia University, Robotics Studio, Spring 2024.
Eight LX-16A servos move the legs, and its computer is Raspberry Pi 4.

Bravo! Well done! Magnificent!

[@richardwatkins6725]

Awesome work

[@tumwesigiremyketezla6423]

nice 🤩

Now I want one

Missed the opportunity to add led matrix or an oled screen in the front

[@Hukkinen]

Impressive! Better than James "RobotX" Burton. Next, on the lateral movement, how about applying momentum to the body to let the behind foot off the surface ;)

[@NIX-xx8to]

What software did you use for robot simulation?

[@nixrobot]

pybullet

[@chipcode5538]

Are there CAD files from your design

[@nixrobot]

At this moment, there are no CAD files available to download, but I am considering whether or not to release all 3D printable parts as STLs on GrabCAD in the future.

[@chipcode5538]

Ok I will guess the dimensions and draw a similar design based on the servo dimensions. What did you use as damper in the foot.

@@nixrobot thanks

[@Jerseylance1]

Nice, but can you share the files sir?

[@nixrobot]

CAD or STL files might be released in some future. Source code might be also released. But due to imperfections in 3D Printing and assembling, it will be not very useful without rewriting it. Therefore, I am planning to make some tutorials, and only after that releasing anything.

[@PerilousPaddy]

Files for the brackets that connect the servos together would be very useful, I like the foot and ankle joint best, the hip joint is also impressive.

This project is very interesting ! Does your project accept sponsorship ? We can sponsor you free PCB and PCBA service.

[@nixrobot]

At this time, this project does not need custom circuits.

[@TenderAI]

would you like to make a tutorial for the robot making?

[@nixrobot]

I am planning to post some tutorials on particular things: from sketching to programming Raspberry Pi

[@zoeyzhang9866]

@@nixrobot Awesome to hear! Wondering if anything we can assist? We'd love to sponsor free services including custom PCBs, 3DP/CNC'd parts. (PCBWay zoey)
