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.

hi all

i made a new base if you want only the yes motion . so you need only one working piston .and two springloade hollow pistons .

hi all

i made hollow springloaded pistons for the only yes base . this to keep the head level . on the left side picture . the two , small pieces wil be moveble to get inline with the neck base , were the tree pistons are housing . video soon . User-inserted image

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.

hi nink

i will test the new mouth in a few houres . then i can post a video so you can see the improment there . a complete inmoove is allot of work . there are so many files old and new together . its easy to print , the wrong parts . personally i find the arms to most diff to do . i didn started that part yet .

I wouldn’t consider using absolutely anything else after you see what the next ARC version is like:)  pretty sure we’re gonna blow your minds.

so yah - make that inmoov cause we still need a bit more time. I was hoping for new year but we’re probably a month or two out. Big job is porting all the 700 robot skills to the new software. And new website and etc etc. stay tuned

hi averyone

for the base with no side movement . i made a springpiston model . the springloaded base looks same as the one with ,only two servo's less needed .

to keep the pistons in place on the base i use piston cups . the cups lean towarts the upper hollow pistons . spring size 80 mm 1.5 wire thikness medium soft spring . User-inserted image

hi averyone

the springloaded head is reddy . only needed one extra servo for the yes motion . the base takes about 2 days to print . modified parts are . the mouth , mouth hinges , lowerbackskull , front top head for the camera to fit ,longer neck ,side inner pistons . headframe .more pictures to come later .averything els is original .there is also, a lockpin for the back servo for the no motion . to keep the screw in place .

lockpin inside the hole gear . it prevent from the servo screw to fall out . also you can see the 20 mm spacer below .

hi :p

one left turneble foot reddy . the color copper is a little like glas , not so very strong as regular grey , black , green , yellow PLA . copper is good for excample outher body parts , not the main , body parts that carry most of the weight .

Very smooth. So you say the copper color is not as strong as the others. Are you going to reprint this part in a stronger PLA?

PRO

#32  

hi dave

yes the copper is not so strong . its good for out side parts . i keep the foot cause it doesn need to carry a load or stand on it . so no reprint is needed . i keep the main structure of the inmoove , in grey PLA .as you can see in the picture . the main structure is grey , and ontop that is the copper .

hi :D

back to the waist part from inmoove . doing some test . i use the HDD standard servo's . you can see how obliquely , the middle bar goes . imagine 50 cm higher .how far the schoulder , will go . i think there's no need to get the pot out . waiting for parts .
