Vr Options?

Does anyone know if the SDK of the Oculus Rift package would work with EZB if there was a plug in developed for it? It doesn't really need to be something as big and bulky as that. Very unfortunate that Vuzix is no longer offering support with EZB. That would work great.

Like the Vuzix, I'd like to pull from the IMU data to move servos and transfer the camera feed from the EZ camera to the goggles over two complete separate computers in different places.

Any ideas or suggestions on how to POC this, would be grateful.

Yeah I created the Hex in Zbrush for my son. Here are a couple pics of concept and then the final model. So many parts...what was I thinking?! It so huge not sure if it will walk but I'm going to give it a try!

OMG, how did you manage to pull this off so quickly?
Great model! I cannot wait to see it in action!:D

Just about 2 weeks designing, and another week til all the parts are completed printing. Then I will assemble and test the legs and add weight to it to see if it will stand up!
#304  
It looks amazing! Which type of servos will you be using...will the body and it's arms also be moving?:D

Great job!

Is there an enclosure for the EZ-B in the back of its body?;)

I’m using the HDD servos from EZ. His body will rotate and tilt, his head will move up and down and side to side.. well as much as he can with his design. Then the arm with the cannon goes up and down, the other arm is stationary ( with hand) . LEDs are in the eyes and cannon. The EZB fits inside the chassis’s. I had to add a piece below for the battery to fit inside of and the device on top houses the speaker. He will be loaded with all kinds of sounds !

@fxrtst: Nice build!

Are you developing new servo brackets ?
PRO

#307  
Thanks! I've developed the brackets just for this build. They would be useless for anything other than this robot. I wanted the servos to look as though they are part of the design. I've printed them in PETG, I will be running a power test next week to see if they will hold up to the weight. At this point I think it will weigh about 12 pounds. Hopefully with the weight distributed over 18 servos it will mange. Because of its size and the flex in PETG I'm afraid it might oscillate as it walks too. Test test test. Time will tell!

As the 3D printers finish up the last parts over the next few days, I want to play around with the idea of recording and playing back animations from Unity. I still need the functionality of EZB and ARC for a full featured experience on this Hexapod.

I'm thinking that a simple plug in that records the animation data and plays it back seems like the most likely (easier?) way to demonstrate Unity and ARC working together-ish. I don't think for this demonstration that it is important to have a "live" connection. But this could be a great demonstration for recording and playback.

@ptp, is this something that is possible? Does anyone know if a CSV file is the best way to go? Then create a plug in in ARC that reads the recorded data?

I've done a bit of research...and Unity XML will save out vector 3 with translations and rotational values...is this something that could be used instead of CSV? Looking at options.

@fxrtst Good luck with the PTEG, I never used this for printing...but I heard a lot of good things about it!
I started printing my robot parts in PLA and experienced, that during time the shoulders started deforming from the weight...so I switched to ABS. Which in turn is not the most forgiving material to print, warping is a big issue. The Prusa Printer has no enclosure, which does not make life easier!

I heart that Polymaker PC-Max should be one of the strongest filaments out there, but it is quiet pricey!


Getting the rotational values formatted into XML or CSV should not be a problem!
Once you get it all set up, a test to check if live playback out of Unity works would be fun too!

If you ever have any time to do a tutorial, you workflow from Zbrush to printing would still interest me a lot...how do you get the exact measures for your servo brackets in Zbrush...it is so hard to do correctly scaled geometric things build within Zbrush...and then having them printed out correctly!
I could never figure out how to do this!

@fxrtst you will have zero problems with the PETG my entire Inmoov robot is printed with that stuff. and Inmoov is heavier then 12 lbs, even Bob Houston's waist that holds the entire upper body does not flex. the only brand I use is MG Chemicals, olther brands I tried were garbage. you bond the parts using weldon 3 it is just like using acetone with ABS.

@Mickey I will indeed do a tutorial on my process. I've learned alot starting 6 years ago with Alan. Zbrush has come a very long ways and can now do polyginal modeling (box modeling), but I still cut my models like its clay with dynamesh. It gets rough and models up close look like cr*ap, but when you print at 100,200 or 300 microns none of that matters. The model resolution is higher than printer can print, so turns out fine!

Yes, I'm up for any test once it gets finished. And XML/CSV outta Unity/ez builde will be much appreciated!

@nallycat Yes I've use PETG for the past two years and it is very strong. But I've not tried MG Chemicals...now I gotta look! I've used eSun and it has not jammed on me or delaminated etc. Stuff is super strong and affordable. Only problems might arise would be from poor design work or servos not being able to handle the weight. LOL.

2 more model to print then its test time. I'll likely just rig the legs to the chassis and slowly add weight to the chassis and try to reach the total weight of the completed model and then walk it.

Here are a couple progress shots unsanded right off the machines.

@fxrtst Now I am getting really jealous!

Btw...what are those metal things near the servos, bearings?

Ah! Those are extra strong servo horns by a company called Actobiotics. They have so many cool modular parts for robots. I’m using a lot of thrm for Alan’s arm and torso.

Man - this is gonna be amazing. Will you be creating a Project Showcase for it? So it can be included in our news letters and features?

Thanks for the info...
I will check those parts, they look strong and helpfull for building!:)
