Servo motor control option

[CloudyPadmal]

Actual Behaviour

PSLab device can be used to control a robot arm set with 4 servo motors. Currently it is done by writing a Python script and there is no option in PSLab Android app to do so. This feature is requested by Marco

Expected Behaviour

Implement a tool giving an option to control servo motors using Android app.

Would you like to work on the issue?

Add this to GSoC timeline. Developer who takes over this issue needs to understand how servo motors work and how to use PWM pins of PSLab device to control them.

@CloudyPadmal i have worked with servo motors using Arduino earlier. Kindly elaborate a little bit further on this so that I can start working on this

It was my minor to control servo's using android, haha what a coincidence. @neel1998 good luck

[CloudyPadmal]

We have a robot arm that moves with 4 servo motors. They are controlled with a code similar to

from PSL import sciencelab
Robot = sciencelab.connect()
Robot.servo4(30,30,30,30)

Idea is to make it more user friendly and give user the ability to change these 30 values to different values so the arm will move differently. You get the idea. It'll be just calling a function but have to make it catchy.
@neel1998 and @adityastic can work together if you like.

@CloudyPadmal that would be great

[neel1998]

@CloudyPadmal that's great

@CloudyPadmal can you show us the real look of the robotic arm, I would love to create something exactly like it inside the app

This would be hard. Something like

@adityastic instead of creating a arm like layout in the app , i was thinking of having a co troller for each four motor, which would make user able to move the servo as interested. It would look more neat

[CloudyPadmal]

Just some sliders would be good without a complicated UI

[neel1998]

@CloudyPadmal i agree with you

[adityastic]

@CloudyPadmal got it

How about 4 dials? that would be neat for an initial interface

[neel1998]

@adityastic i was also thinking something like that. Let's both create some mock ups and then decide which layout to opt

Sounds Great, Lets talk about it on the public channel on gitter

@CloudyPadmal i have made 2 mock ups for this functionality. Kindly share your views so that i can start working on it.
