My Ezri From Bavaria

I started searching for a driving camera. The best thing I wanted was a robot with which I could grab things. JD was perfect for me. I experimented with JD but he runs very slowly. I tried to lengthen the legs. There were problems with the stability. I bought him wheels.

With the wheels he could not drive small steps. Now I got Rolli and built a centaur.

After 30-40 minutes the battery was always empty. I needed a big battery. Now the robot can be used for 6-8 hours with only one battery.

Controlling two arms is not easy. Except for the optics, I found 2 arms senseless. I put the robot on a movable arm. The stress on the rotation servo is too great. The stability is not given.

I tested 2 weeks all positions for one arm. I also wanted to be able to store objects in the body. Then I had the perfect idea. Through the integration of a vehicle and working mode, I was able to fulfill all wishes.

The chains have always slipped. Either they were too tight. Or these were too loose. For normal operation these were ok. As soon as the robot turned, the chains slipped.

Now I attached to each drive wheel a self-sealing tape. Now the chains work perfectly again.

Now i have make a first operating Video with the new Version from my robot EZRI.

Here you can see the robot with full operating arm and grabber.

Nice work! well thought out and great trouble shooting technique.

You have some very clever ideas there. I was already planning to reconfigure my Roli project, and I have some new ideas based on what you have done here.

This is a great project! Thank you for sharing

Very nice design. Thanks for the step by step description. Have you looked into anyway to make the drive train quieter?

Thanks for the nice words to all. Without your help, I could not have done it.

Have you looked into anyway to make the drive train quieter? 

I hope i have translate this right. Google makes really stupid things.

Rolly is really loud. Yes. But he works perfekt. Never touch a running system. My EZRI drive in the garden perfekt.

The breakthrough came with Blockly. This is simply awesome.

All peoples make selfies. Now i think, why does my Ezri not make selfies? I have build a stand for my old Rollei Actioncam. Now i have added a selfie funktion.

Now, EZRI has visit a new brother. I have become from a old man a Omnibot. He is broken and not usable.

But EZ-Robot is great for this. I have see her a lot of examples.

Ezri must be alive. She is the perfect robot for work, voyage and have fun.

@stiko I really liked the selfie video

Great work'

Which headset is good for speech recognition? Do you use push to talk? If I have too many words, I do not get very good answers.

What are your best experiences for a conversation? Which project has the greatest success with you? Currently, a lot of speech is about macros. But that works very well.

haha great a robot taking a selfie.

Hmm, i see. I must test some headsets alone.

Has anyone changed the speaker? I want to build a soundsystem to Rolli. This soundsystem need 5-6 Volt. Can i grab this directly from the EZB?
