Check out this robo-memorabilia, MRL'ers.

Just made and ordered this cool mug from the Spreadshirt website along with an MRL logo T-shirt.  The mug was only $14.50 USD with the logo.  You can upload any pic and design it on the web-site.  I'm going to do an inmoov/MRL shirt too. Free advertising.  


InMoov knee actuation

This my latest refined knee model which is running with the service DIY Servo.

I love that service by the way!! Well let say, I just love MyRobotLab!

It's incredible the evolution it has under gone since I started this project.

Before everyone starts to break it after the Manticore, I am asking Santa to implement velocity in that service to see what is smoothness of movement on payload, and if it can still control with enough power.


Setting servo speed in Arduino and Python

Humanoid's picture

I have always just used my servos at the servo's full speed. 

This is a problem when setting servos if something goes wrong. No reaction time before breakages occur. 

Q1) For stand-alone Arduino - Is there a line of code I can add after "servotest.write(90);" to lower the speed of servo movement even to a quarter or a half of normal speed or is this too simple?  I have been using the delay() command but I gather that doesn't affect the speed of movement only the delay between movements. 

BLDC servo

It seems that some people are interested in BLDC servo.

Here is my very first work on that :

BLDC motor and gearbox with PID control by arduino under labview.

Resources by Service

Ahoy to my fellow MRL'ers!

I had an interesting thought while letting my turkey settle in my stomach (U.S. Thanksgiving Holiday Today). Is it or could it be possible to allocate resources for a specific service inside MRL when doing Runtime.createAndStart(...)  It is supposed to be possible to do java -Xmx1024m -jar myrobotlab.jar but does this just give the MyRobotLab process those resources?  I have been digging into Runtime and createAndStart but I am not seeing anything that looks explicitly like what I am wanting to do?

I will write up how this MAGIC all worked but check it out... It WORKS!

The Robot with Two Brains REVISITED

A few weeks ago I was trying to determine how to pass data between services running on separate instances of MRL running on a Mac Mini and a Raspberry Pi.

Damn .. from its first nervous steps a couple years ago, to now backflips !  ..
That's just ... wow .... speechless

Thanks @Humanoid for sharing the link !
