As I'm trying to polish up Sabertooth, Joystick, and provide an interface in python you can do this
motor.attach(joystick.getAxis("y"))
I noticed MotorControl has getPowerLevel() & getPowerOutput()
Next version 'Nixie' is coming soon !
Help us to get ready with MyRobotLab version Nixie: try it !
Example code (from branch develop):
#file : FileConnector.py (github)
# FileConnector crawler # Crawls a directory and publishes a docment for each files found def onDocument(doc): print(doc) fc = runtime.start("fc","FileConnector") fc.addListener("publishDocument","python","onDocument") # start crawling fc.setDirectory(".myrobotlab") fc.startCrawling() sleep(5) fc.stopCrawling()
Example configuration (from branch develop):
#file : FileConnector.py (github)
!!org.myrobotlab.service.config.ServiceConfig listeners: null peers: null type: FileConnector
FileConnector is a service that crawls thru a folder and publishes one document for each found file.
Hi,
I 'am still slowly trying to learn the software but have come into another problem, by any chance will anyone know what I need to look at to try and get the head working, I have an Arudino mega 2560 setup as the left side, I can start the left hand and that all works fine but when I try and start the head I get an error
[AWT-EventQueue-0] ERROR class org.myrobotlab.swing.InMoovGui - can't process [start head]
Myrobot lab version 1.0.2577
Thanks
Matt

DatabaseConnector is a service that executes a select statement from a database and publishes a document for each line. The example is using MySQL database with the example database that is included when you download it from here: https://dev.mysql.com/downloads/
It uses the jdbc driver so it can be used with most databases.
Dom wants to use A6 & A7 on the Nano
I'm about to add the 2 pins in the Arduino service pin definition for the Nano .. but what are the "real" addresses of these pins ?
They are not listed on any documentation .. I found this excellent description regarding these mysterious and silly pins on the Arduino forums..

CsvConnector is a service that reads a comma separated file ( .csv ) and publishes one document for each row.
The BoofCv service is a wrapper for the BoofCV open source Java library for real-time computer vision and robotics applications.

It has a lot more possibilities than what has been used in MRL so far.
Careful if they are closed, tracking will get borked :)
Service refactored, as test, to use any servo controler

MotorHat4Pi is a motor connected to the AdafruitMotorHat4Pi driver board that can be used on the Raspberry PI. It can drive 4 DC motors ( implemented in mrl ) or two stepper motors ( yet to be implemented ).

AdafruitMotorHat4Pi is a motor driver board that can be used on the Raspberry PI. It can drive 4 DC motors ( implemented in mrl ) or two stepper motors ( yet to be implemented ).
https://www.adafruit.com/product/2348
To use the motor you need thee services running on the PI.
1. The raspi service. http://myrobotlab.org/service/RasPi
2. This service. It represents the board it'self and communicates with the Raspberry PI using the i2c protocol.
3. One to four MotorHat4P services, one for each motor: http://myrobotlab.org/service/MotorHat4Pi
