Rhoby 0.5 or Born to be micRhoby

Hello for everyone!

So many time passed from my last post here. I think is a good time to write about my work and projects.

My work in social robotics field started from Rhoby 0.5 project.  It was funny and small robot with two motors and some basic sensors.

Next serious step in social robotics – Rhoby 1.0, complex and useful robot which will be assistant for kids in learning some disciplines like foreign languages or geometry.

But how I said above – Rhoby 1.0 is a complex project and I need now less difficult projects and tasks, which will give me possibilities to make small steps for building something big . That sounds like very efficient way in my case.

So, let me explain you about “sidekick” for Rhoby – micRhoby.

Rhoby project (ver. 0.5b)

Rhoby – open-source platform for creating a small social robots.
This robotics platform ideal for learning kids to programming and electronics. But most important what is it very useful for teaching “special” kids, with autism syndrome for example.

Omniwheels is here.

Time to uncover some details about future Rhoby ver.1.0.

Golem is dead?

Not a big secret what I interested in blockchain technology. I very excited by projects like IOTA , Stellar or Blockstack .

Another one which take my attention was The Golem Project , I found it is very useful because sharing computing power for science calculations is a cool idea in the age when we own a thousands times more computing power than computers on Apollo program spaceships right onto our desks at our homes.

But through the time this project dissapointed me, because developers work very slow and lazy, commits at github is a rare event, founders only visiting a different conferencies, but don’t work on the project. For the moment, at the end of January 2018, project still in alpha testing. If you right now look at the exchange schedule , GNT is falling last few weeks even don’t touched the high ever.

The Golem Project is dead?

Why do I think that the best cryptocurrency for saving money right now is Dogecoin?

Dogecoin was present in 2013 as a joke. Cryptocurrency based on Litecoin and using Scrypt technology instead SHA-256. In 2014, the Dogecoin Foundation managed to raise money for the NASCAR racer Josh Wise and the Jamaican team in bobsleigh.

CNC Router quick update

When we started this project with my friend, we have very ambitious ideas and we made a big mistake – began right off built a big CNC machine without any experience in these field.

One of the main problem is twisting of the gantry.

If you look at the picture, you can see white contour which shows the location of the gantry bulk, Z-axis moving along this beam. Violet arrow show the shoulder between bulk and weight(red contour around milling tool) on the Z-axis. Plus, Z-axis itself have a big height (green arrow). All this construction’s “features” giving a twisting gantry while X-axis or Z-axis moves.

Now I try to solve this problem using little changes in assembly of the Z-axis.

Stay tuned.

Some design concept

Rhoby is a companion robot which designed to interact with people for the purpose of teaching them new skills in the fields of exact sciences, philology, etc.

Rhoby has a two arms, one for the pencil, second for the “tablet” – LCD which displays a status of teaching assignment.

Head of the robot consist of OLED-display for eyes animation – one of the methods emotional communication with human, plus on the “face” is placed a speaker for verbal communication. On top of the head two antennas which actually is a microphones for hearing and determining the direction of the sound source.

Time is now

That was a warm spring evening, when I sitting with my friends in pub and discussing robotics, Tim had asked Siri about subject of our dispute, and of course, his smartphone give him a link to Wikipedia. But at this moment I have realized, TIME IS NOW.

Work in progress

Work in progress. Our first CNC machine on the way to be working tool. Now our main aim is calibrating all axis mechanical and program.
