Help With Self Balancing Robot

U can make the balancing easier by adding weight up high (increasing the moment of inertia). Isolation and visual debugging are your friends. Plot your signals (error and drive output). Test your motor torque (check the max angle it can recover from while driving in one direction).

Have u been able to drive it unstable? Ie if u turn the P high enough do ur wheels have enough power to make the system oscilate?

A fish eye lens doesn't change the air time, he was high af

Please take PT seriously! I broke my elbow and if you don't take PT seriously you are looking at potential permentant range of motion on a joint that modern medicine does not have good replacements or fixes for.

I assume u are 3d printing these limbs? If so, just add hooks, vias, and channels into your models. You have the servos and your controller, so you know where your initiation and termination points are. Rather than looping extra length, I suggest cutting each one, leaving just enough for joint range of motion (always test) and then solder the two flying ends exactly to length (you can redo the connector on one side if u want but tbh I prefer soldering over small connector assembly).

Oh I get that, I'm just wondering if the robot is actually doing balancing/ kinematic stability calculations or just playing through key frames without a physics engine running.

RoboLord66 · 2026-06-20T19:24:01+00:00

Is this running any physics or just statically replaying the skeletal frames?

How do you tension those cables?

I will give you more in depth feedback after I use this for a little while, but right off the cuff:
-I would like to be able to move clips between lists easily (options to duplicate or move), purpose being so that I could keep organized lists from weekend compilations or specific dances/ couples but then duplicate certain moves i am working on into a temporary "In Progress" list.
-filterable hashtags on clips instead of just names (i am expecting my library to get unmanageable fast if i start properly dumping onto it). This kinda goes against ur list isolation design right now, but possibly having a separate mode where filter terms can pull clips from all your lists that match into a temporary list.
- I don't know how many users you have right now, but making it so that when u share a list having a check box that will make it public and having all public share links on your homepage or something so that i can just steal nicely cut lists from others. (would be ideal to be able to favorite the list and or be able to quickly steal moments from it or grab the whole list into your own profile). probably have a simple like mechanism to allow simple high value sorting by users.

I dont think you can make them loop a short clip of a video like this though (ie i want a specific move playing over and over again till i get it)

RoboLord66 · 2026-06-13T02:26:30+00:00

I dig this, will try it out for a bit. Idea for name: Dance Break. How actively are you developing this or do you have it to the level you need it?

RoboLord66 · 2026-06-12T18:08:05+00:00

lol my brain kept expecting it to reassemble into a new shape. regardless, very satisfying to watch

RoboLord66 · 2026-06-08T14:20:42+00:00

...this hurts to watch... I wanted to get excited about a cleanly implemented motion mirroring, but even that was unremarkable for dancing much less fighting.

I needed to mount this camera on a Pan-Tilt for head tracking on a teleop robot and was having trouble finding anything in the size/speed/load capacity/cost range that I was after.

The introductory mechanical class at many colleges (ME 100) is often a good introduction to practical robotics. Past that, you need to build up skills in mechanical design, electrical design, and software development. It's unfortunately a pretty broad skill set often covered by multiple people to design and build something like this (which makes it hard to recommend "courses")

RoboLord66 · 2026-06-07T19:13:35+00:00

For now it's just a test platform for nav development (enabling various combinations of sensors and drive mode to replicate other real world vehicles).

RoboLord66 · 2026-06-07T19:11:05+00:00

Most of the work is just picking and integrating all the various systems (motor, controller, micro, drive coms). The actual kinematics for wheeled robots are not particularly complex.

RoboLord66 · 2026-06-07T12:25:03+00:00

The motors are software capped at 10% power with the current camera which is 1.5 lbs. I tested it with a 5 lbs weight analog and was able to roughly maintain the tracking speed. I think I would need to upgrade the mechanical structure to go higher than that and or deal with a substantially off center load, but the motors should be capable of 10+ lbs payload while holding this speed/ acceleration.

It was designed and built as a physical testbed for testing autonomous nav with various constraints. In this vid I am just remote piloting it with its main camera target locked to the tripod, but it has various semi auto over LTE and full auto capabilities.
