Interested in one screen accurate.

Update: I’ve since moved on from Blender and am now using a package called Bottango. It’s great, free, and well supported by the author. You can set up the 3D model of your robot mechanism (even import existing 3D model assets), assign joints and servos, build the animations, and control the...

I’d be interested in seeing your progress pics. I’m working on an Ashford costume for DragonCon and could use some inspiration.

That was intentional to mask the audio enough that YouTube and Facebook would not block the post due to copyright infringement. Also, he's a robot so the noise should be expected :).

First pass of a few seconds of animation. Was still getting the hang of it. This was 120 frames out of a total 1700.

Prior to today's video, I worked through getting the model into Blender for animation and digital character rigging. Each bone in the armature corresponds to a joint servo in the physical animatronic. Writing my own animation control system in Python to take the exported joint data and drive the...

Progress on the animatronic C-3PO: The figure animation is built in Blender, joint angle data is exported to JSON, then my Python code reads/parses the data and velocity and acceleration parameters are manipulated in real-time to drive all 16 actuators to get the motion seen here. Still lots...

Hey Cam! For this test I was using the software that comes with the Pololu Maestro 18 channel servo controller board. I’m looking at several options for control software beyond the VSA I used last year, including writing my own. I’ve moved the body turn servo up higher into the pelvis area...

Thanks for the kind words. I have a few ideas for the next one. Maybe Hondo Ohnaka, maybe another 3PO with more functions, maybe something else.

It's been a while since I've provided any updates. Since August of 2019 I've changed jobs and began working with a large animatronics company which has taken most of my time, but has also revealed so much new knowledge to me. As a result I've re-thought and re-designed most of the internals for...

This is awesome.

Mechanics and Motion - Right Arm V2 Servo Test Here's the first test with coordinated movement of all 5 servo axes of the V2 right arm mechanism (shoulder, bicep, elbow, wrist pivot, wrist tilt). I removed the V1 gearmotors and linear actuators and replaced them with servos for better control...

Mechanics and Servos - Shoulder Joint V2 I made some progress on the V2 shoulder joint these past few weeks. I'm replacing all of the arm and shoulder gearmotors and linear actuators with heavy duty robot servos. Every motion axis will now move via servo, making control and programming much...

He is some sort of god.

Hey all, sorry for the time away. Lots going on. I'm in the process of reworking the wing pack for D23 Expo 2019 in August. Trying a different mounting solution for the secondary axis servos that will reduce the overall footprint of the mechanics by about 30%. So maybe it will look a bit more...
