Information about openCV

Gule's picture

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

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

Random Service

javadoc

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))

 

Example of Web UI list of current random method events

Example for develop:

[[Random.py]]
