ZOE : a machine that resembles a living creature in being capable of moving independently


Skip to comments

Since my robot is running on a Raspberry Pi, which is now supported by EZ-Builder,
I decided to evolve my current project K[8] into a new one called ZOE...
First steps will creating a new servo setup which supports Dynamixel Servos, 
and a new Conceptual design!!

@Jeremie I will be away for two weeks starting Tuesday. When I am back I will continue to keep posting on this one!!!:)

@nallycat The first picture was just a 3D image...only the idea of how I want the robot to look!! Now that I have printed the parts I can start building it!! I am happy you like the first picture better, because that is the way I want to go!!:) 
I will build Grippers that look like hands!! And will try to put Zoe together when I am back from my trip!!
So finally I could make some time to continue with my new project...
I tested the Dynamixel AX-12A and theLewanSoul LX16-A servos and decided to go for for LX 16-A...

I was kind of counterbalancing the ideas of having a well known brand which is fabricating consistent products,
and is very known ( so there is a good forum and you will always find help for stuff that you cannot figure out by yourself )...
And the cheaper product, which has not been around for that long and seems to be a bit like the cheap replica of the first one mentioned.

The thing that made me go for the LX 16-A was on one hand the price, which is one third of the Dynamixel,
but mainly it was the ease of use...

I tried a lot to get the Dynamixel servo going, but driving it directly from my Raspberry Pi was not working for me!

But for the LX 16-A,
I found a good library on Github, which works perfect, and can be used without any tweaking to control those servos with my Raspi! 

Also these servos are doing great with EZ-Builder so I do not loose any functionality of the EZ-Builder software!!

So I got down to design and print some parts, and am getting ready to move on with my robot!!:)

Hmmmm I cannot upload pictures...that is weird!!

It always gives me a comment already posted message...


Now I got it to work...it seems like I had to post text and/or wait before I press the Submit Changes button?
Strange...it would be nice if someone could look into this!:)

These are the parts that I managed to print so far, I hope I can make time to build the missing ones soon!:):)

Still not done building all the joints, but I will be able to make some movement tests with this rig already!!

And now comes the sad chapter of salvaging the parts from my former robot project!!:(
I will try to keep at least the servo functionality, some boards will have to go though...
