Trying to find the optimum solution for a robot that uses all the pieces in the development kit.
I am leaning towards a Fork of Zowi / Bob / Otto, the little open source creative commons (supports commercial license) biped robot. It has 4 servo's on the legs and there are some forks that have servo's for arms. What it lacks is a decent brain as it is arduino based so it can only do basic moves so I think the EZB would add a lot of value.
I printed a Zowi off and it looks like it is fairly close to what is needed.
Logic is use the existing HDD servo's for legs (2 Servos for feet and 2 for legs). They fit perfectly into the Zowi legs.
Use the 2 full rotation servo's for arms and add the camera and distance sensor.
Looks like the only major change will be the chassis design so it can fit the top of the EZB V4 and create some arms but the legs are pretty good and fit servos and the battery holder fits one of my 2S lipos.

pre order means if the maker has enough clients to make the robot and to,
start the assemble line.if your lucky you have a robot in maybe a year.
dont contribute on stuff like indiego.its a rip off.
Since you built the 3D printed version and used EZB HDD servos, could you look at the retail version specs and figure out if EZB servos would fit?
Thanks,

Thanks for sharing the info on your printed as well as the retail version of the dancing robot. My grandkids got so excited and I just had to see if I could build one completly out of EZ-Robot parts
Using JD bare project as a base, create a Cubee robot using only EZ-Robot parts. I think this approach would help in STEM education as standard EZ-Robot parts were used. I used @DJ tip on AutoPosition to create dance moves
Here is the standard layout of JD servos
The only servos used from the JD Cubee build are:
D12, D16 Hip joints (replaced with rotation servos)
D14, D18- ankle joints
The goal is to edit the frames and actions in the JD AutoPosition control to create the desired dance moves
Optional Try using standard JD feet as the ankle joints. The feet would provide great support but add an extra servo(there are 2 servos in each JD foot) that could also be used to lift a leg (D14, D18)
When I edited the AutoPosition control to add in my new dance moves, I was not able to get the servos to respond to the frames or actions. I’m not sure if this is what fixed it, but since I was only using 4 servos out of the 18 in the JD bare project, I wondered if the frame was trying to communicate with all 18 servos
So, I assigned all unused servos to NA. My frames and actions are now working, but I’m unsure this is what fixed it.
I only built 2 Actions; Ankle Flex and Twist. As you will see in the video, I have no rhythm or style but this is just a proof of conceptthe exercise is left to the student
One feature this design has over the original Cubee is the standard voice recognition built into the ARC. My granddaughter nicknamed the robot floppy guy because he was failing all over the place with standard JD Actions.
Here is the video
If anyone is interested, I can post the project

You are right about the big feet!
I was just worried about him tipping over on aggressive moves.
Since the JD body has built in arm servos, one could also add arms.
To keep the cost down for an entry level robot, DJ could remove those servos.
Thanks again for the inspiration on this new robot, my granddaughter loves it.

Changed to smaller feet and more moves

BTW, Oh My GOSH, does anyone else think Frank's JD Cubee looks like a "Batteries Not Included" robot? As a child of the 80's I loved that movie and the "little guy".
Thanks for the compliment. Your photo made me think of adding a head and in keeping with my self-imposed requirement of only using EZ-Robot stock parts here is what I came up with:
This of course makes him pretty tall, getting away from the Cubee clone idea, and he getting so top heavy that I had to use a bit bigger feet. Its almost as big as JD.
I'm considering removing the unused shoulder servos to balance it out. the Dodecagon Body is already enpty
It would be nice if there were some "slim" EZ-bits extension cubes, just male to male connectors for close fitting servos
Regards,
Frank
Here is my current attempt at matching those "Batteries Not Included" robots
I used the dome from AdventureBot and added music. Was able to go back to smaller feet and it has good balance
and the video
Frank
Thanks for the feedback.
Would you like me to make the project public?
Regards,
Frank
If you look at dev bot the Servos are mounted horizontally versus vertically so they can twist allowing him to walk forward but not sure we can do this on the JD Robot version.
I’ll try your config with feet to let you know if he balances
Frank
I implemented your short leg design and it works great!
I also removed the unused servos in the JD body and Its very stable.
If you decide to offer your 3D print services through the EZ-Robot link I'll order a set

Thanks again for the idea

You don't want my printing services, I would have to pay you. Did you not see my thread on me begging for 3D printing help. Multiple EZ Robot experts hand holding me and I still can't get a decent print job. I would blame the worlds cheapest Prusa I3 clone I use but other people have the exact same printer as me and their print jobs are amazing. https://www.ez-robot.com/Community/Forum/Thread?threadId=10750
