Future Of Servo Speed Control

This will be the future !  Please be part of it .. thumbs up or thumbs down - if thumbs down state why.. WHOOHOO ! - this is what I have so far....

For information

In prep for setting up my InMoov eye camera, I'm measuring camera fps in MyRobotLab:

NeoPixel service not working with more than 11 LEDs?

StefanEkstam's picture

I'm using the NeoPixel service with version 1.0.1723 of MRL, but it starts behaving weirdly with anything more than 11 LEDs.

I've tried this on a number of different NeoPixel strips and rings, and they start blinking in an uncontrolled manner when I configure then for 12 LEDs or more. With 11 or less everything works great.

The strips and rings are working perfectly, and they perform as they should when programmed directly outside MRL, e g in the Arduino development environment with Adafruit's examples.


New Years Resolution - (Better Resolution !)

GroG's picture

Before the year is out, I vote we update the motor, servo, & position interfaces from int to double.

Double allows us better resolution for the future, and ints can change into doubles, but not the other way around.

And if there are questions to use a Double the object vs double the primitive :

Running myrobotlab on an Android tablet

I got myself a nice Android tablet for Xmas and I was wondering if it is currently possible de run myrobotlab on it.

I have noticed that there is an Android project on github for myrobotlab but it has only one activity so I guess it is not finished. 

Has anybody tried to run it on an Android platform? or do I need to port the code to Android?



Servo.detach() Published event

Hi ! someone know how can I intercept a detach() action of a servo .
If not possible is it possible to implement a Published detach information ?

Because I use servo they didn't detach via pwm ( I use a relay to micro shutdown +6v )
And don't want to add multiple non standardized line in script


Raspberry Pi, Pi Camera, OpenCV 3.1.0, MRL

As a proof of concept I wanted to see how the Raspberry Pi Zero would hold up to be used to control the Pi camera for the eye of my InMoov along with the head and eye servos

stepper motors's picture

Is there a way to control stepper motors want to use them as a base for a robot differential drive
