I've always wished I had started a Project Showcase type of thread when I started running my InMoov robot with EZ-Robot. So I'm going to start one now. The first few posts are recaps of the threads I've done, I'll put a link to the original thread so if someone wants to see the discussion they can. Anything I do in the future will be posted on this thread.
Here's the first thread I posted with my InMoov running on EZ-Robot. Original thread - https://synthiam.com/Community/Questions/6670

Norm is a very fitting name, no?

Hi everybody, Its been awhile and Im back to humanoids again. Last march, I bought my first 3d printer kit and its been...

Hey, still looking for a propper way to share stuff here on the forum... This is mindblowing!!
Hey Bob.
Really enjoyed reading through this thread and watching the videos. I remember when you started building this guy. The mods and improvements have really paid off. Truly great work. And the base really looks the part too.
I've been looking to replace the wheels on my InMoov base so I got one of these Hoverboard wheels, www.ebay.com/itm/HOVERBOARD-REPLACEMENT-PART-TIRE-WHEEL-MOTOR-SCOOTER-ELECTRIC-6-5-1-PC/352374853275 I was hoping to run it with a 2X12 Sabertooth controller, however, it has 3 power wires and not being an electronic dude, I'm looking for some help from the community on how to set it up. I have looked at a video that fxrtst posted in this thread post 26; https://synthiam.com/Community/Questions/11497&page=3 It's being run with an H-bridge in the video and if that's the way it has to be run, OK, but if I can run it with Sabertooth that would be better.
Anyway, looking for some input, thanks.
If it's a brushless motor you are going to need a brushless motor controller... I am going to go out on a limb and say that it won't work well if at all with the sabertooth...
Hey Bob.
They are brushless motors.
You will need a special control from odriverobotics: https://odriverobotics.com/#odrive
Take a look in the forum: https://discourse.odriverobotics.com/t/hoverboard-wheels-odrive-board-arduino-pi-for-robot/721
Those motors include encoders I believe you need them to control the speed.
To soften the blow a bit brushless motor controllers are ubiquitous in the hobby world and easily controlled by servo PWM methods. Perhaps something from the RC car world could be used here.
Most of my RC car, plane, helicopter, etc. parts seem to end up somewhere inside my bots.
Thanks for your comments. I'm looking to replace noisy 12V motors I current use and still run them with ARC. I've looked at the Odrive but not sure that will operate thru the EZB. Can anyone recommend an H-Bridge that will run these wheels and be compatable with ARC? Thanks
Hi Bob, Aren't those motors 3 phase though? An H bridge won't power those. You need a controller that pulses them like a stepper. H-bridges are for brushed motors. I think those are brushless. You need a brushless speed controller. They are controlled like a continuous servo from the EZR controller
Here's an example. Maybe not perfect but you get the idea

Hello everyone. It's been awhile since I posted anything here but I wanted to share my work on the new InMoov i2 Head Gael has released. After printing and assembling the head, I was able to fit an EZBv4 in the head to control the 18 servos. This left me with only a power cable running down the neck. Then after a couple hours creating some auto positions and a script, I came up with this. I see that people that aren't using Ez-Robot products and Synthiam are having a difficult time programming their projects.
