The Search for the Holy Grail (Free Form Speech Recognition)

Sniffing the intertoobs has lead me first to this:

which turned out to be dead - or looks that way .. Sphinx 

http://grasch.net/projects Simon project which leads to ...

That is a C++ (with possible dependencies into KDE yikes!) program .. which can make it a little tricky interfacing Java to it .. but we've done it before..

Hmmmm


Joystick Control Remote Servo over TCP/IP

Two instances of MRL borged together as One !   The colored tabs are the views into the remote instance's services. Remember MRL is NOT the GUI !


InMoov Design Request

GroG's picture

I think the InMoov design would benefit from a "tilt-able" kinect. The kinect comes with its own tiltable stand, but controlling this through the kinect driver is very problematic.

We need a single servo - tilt gimbal for the kinect.  
The kinect is the most powerful sensor we have, but we can not look down and see what is in front of us !

This post is to examine the details of Pingdar.  


Here We Go - MRL on Android (again) :) !

Alright - hangout telepresence, diy occulus rift, an array of sensors, acclerometer, gps, compass, gyros, bluetooth, good speech to text, & wifi are just too much !

TIME TO BORG THE DROID ! 


Borging ...Parallax Platform

GroG's picture

Keyboard control of the platform is now enabled - the numpad keys do the following.
7 - left wheel forward 8 - both forward 9 - right forward
4 - left forward right reverse 5 & spacebar - stop 6 - left reverse right forward
1 - left reverse 2 - both reverse 3 right reverse

Theoretically it could be put on the floor and we could test it - probably would want to go through a test of the key pad first.


MouthControl and Burning Servos

GroG's picture

I have a feeling that MouthControl is consuming servos at an alarming rate.
I think Gael has had 6, and MastaBlasta had 2 ..  Most likely there have been even more casualties...

I have a feeling I might know why this is happening, and I would like to refactor this service.

I think min & max is being incorrectly reset - I would like to simplify some of the structure and remove the resets.


Software from iRobot

Free control software - worth checking out and reviewing .. Although, I was not really impressed with the interface.  A more "simple" mode would be to tilt and turn the tablet for speed and directio of platform, with thumbs controlling the gripper.


Python Community Libraries

Hello MRL'ians :)

Wvantoorn mentioned I should start a post regarding our future Python Community Library.  Right now, our library is checked into github as part of the MyRobotLab repo.  This repo is primarily Java (framework) code - but the library has grown significantly, and there are many scripts floating around which would be nice to share, modify, modularize & improve.


Serial

Serial ports are about the most common means for computers to talk to periphery devices, so of course this makes them important in robotics.  They are older than the internet and can sometimes be very frustrating.
