Python code to enable x,y plotting from the neopixel service, an inviting rabbit hole.
Many Matrix displays have a serpentine LED pattern. This means that odd and even columns are reversed.
Next version 'Nixie' is coming soon !
Help us to get ready with MyRobotLab version Nixie: try it !
Can anyone show me where I can find information about how openCV is integrated in MRL?
I try to get openCV to run on Ubuntu 20.4. With manticore version when capturing a frame webgui freezes, no interaction is possible. With nixie, there is an error message "could not get valid frame".
Which version of the openCV libraries has to be installed in the system? What python scripts for openCV come with the installation of MRL and where can I find them?
Thanks for any support
gule
Can you please give me link to nixie. My pc was capture by Randsome virus so i lost everything please
Example code (from branch develop):
#file : InverseKinematics3D.py (github)
# start the service inversekinematics3d = runtime.start("inversekinematics3d","InverseKinematics3D")

Hi All,
I have continued to work on the robot legs and have them 'static' walking
All the main support parts are made in aluminum
Still using RoboClaw boards for driving the 10 motors, all motors have encoders
New all joints have angle sensors
I have a IMU on the platform and am using roll and pitch
power is from 3 LION 3.7 volt cells on the top back, cells are from a hybrid car
I finally listened to Ray and have the weight on the top, inverted pendulum
Hello everyone! How do I add new Python libraries to myrobotlab. So that my Python 3.7.7 scripts can work?
Example code (from branch develop):
#file : ServoMixer.py (github)
# TODO: Implement this script fpr servomixer = runtime.start("servomixer","ServoMixer")...
Example configuration (from branch develop):
#file : ServoMixer.py (github)
!!org.myrobotlab.service.config.ServiceConfig listeners: null peers: null type: ServoMixer
General purpose service to orchestrate servos.
Example code (from branch develop):

The Random service can create random messages with random parameters. Any method accessable can be called at some interval with ranges of parameters. For example, if you wanted a Servo to move at some interval between 1 and 5 seconds between 35 and 165.
random = Runtime.start('random','Random')
random.addRandom(1000, 5000, 'servo01', 'moveTo', random.intRange(35, 165))
