hi all

I've created a modified version of the EZ Robot head, featuring both side-to-side and up-and-down (yes) movements. This new design includes an improved base for the head, accommodating three additional HDD servos. There's an option to install two cameras, with the base designed to allow passage for a second camera cable. This setup is ideal for incorporating additional IoT devices or EZBV4, for instance, for LED lighting. Conveniently, there's no need to remove the potentiometer from a servo, as the 1 to 180-degree range provides ample movement. The base height is 7.2 cm.

The pistons are original components from InMoov, and the neck base in EZ Robot is correctly designed.

For moving the side pistons, adhere to these settings:

Programming

Adjusting the side pistons can be a bit complex. Start by calibrating your HDD servos. Then, align the inner piston with the holes in the piston base and secure it with a screw. For the second side piston, align it similarly, then disconnect the IoTiny. This allows you to manually adjust the previous piston to properly position the second one. The original documentation on EZ Robot is extremely helpful in this process.

Parts & Materials

You'll need 3 extra HDD servos and grey PLA filament. The drive shaft parts should be printed with a 35% infill and a gyroid pattern in your slicer for enhanced strength. Other parts can be printed according to your preferences. Additionally, there's an optional neck extension, offering one to three extra vertebrae for more piston movement space. In my experience, the two-vertebrae option works best.

Nice work Nomad.   I am wondering how to move forward.  Do I do this mod and if so will it align with actual inmoov? What is Jeremie working on?  Will I head in one direction and then have to change to another.   I think I may as well go forward and build the entire Inmoov (I put filament on my Christmas list) but I would like to have something that is at least loosely supported and a roadmap. InMoov changed direction and primarily uses MRL but its a terrible platform to work with so I don’t want to go down that path.  If I wanted pain in my life I would use ROS.
