Suggestion For New Motor Control Movement Panel

I have a suggestion for a new Movement Panel for controlling H-Bridge Motor controllers.

I have noticed that since I switched over to the EZ-B board from R/C control that I am not longer able to accutately control the movement of my robot. Using the R/C equipment and two joysticks in the Tank drive mode I could percisely steer the robot diagonally as well as forward and reverse because I was contolling each motor independally. Now that I am using the EZ-B board I can no longer do that since the Movement Panel is layed out on a X design and control both motors together for forward and reserse movements as well and turning left and right.

Is it possible that a movemnt panel could be created that allows two drive motors to be independally controlled give more persice control of the steering.

That way you could have one Movement Panel of either side of a tablet and using your thumbs slide them up and down to control the direction of each motor. This is extremely useful when both drive motors are not perfectly matched and spin at slightly different speeds which cause the robot to not drive in a straight line. This would also give to operator better control for a more fluid movement to the steering of the robot.

Just a suggestion, but one that would be highly useful.

I like the idea of having multi h-bridge controls. My robot jack needs one for the tracks to move forward/reverse left and right. I also need one for the 2 motors to raise the robot up and down and to climb stairs.

@Tymtraveler, I'll be posting an example to the cloud later with scripts and keyboard controls to move a hbridge without a movement panel. It may vary slightly from hbridge to hbridge (i.e. different types) but the basics will remain the same:)

@ Rich, with the script will I be able to say "Robot rise or lower" that's all I want it to do I think with my design I will not be having him climb stairs. I just need him to rise up and open the beer fridge and grab the beer. I am still learning scripting but I figured out that when the door is open I made a devise that will push a beer out so JAC can grab it. My script will work like this if it is possible.

  1. Command: JAC get me a beer.
  2. JAC runs script to first search for a glyph on the fridge that will guild him to the fridge.
  3. Once he finds the fridge he will run a script to first rise up.
  4. As he approches the fridge he will activate a motion detector that will pop open the door using a motor and bracket that is installed on the door
  5. Beer will be in a tray that will be in the front.
  6. JAC will then move forward and grasp the beer, then back up.
  7. Then the door motion detector will time out and close tha door once JAC has backed away from the fridge, then he will run a final script to find me (face rec)

This is one of the reasons I want the Kinect and face rec for JAC.

There's a script in Examples called "Two HBridges"

That'll teach me not to look in the examples, I've just done my example:) Oh well, it gave me something to do, I'll have to see if I did mine the same way or a different way. It may sound crazy but I've barely looked at examples.

Although I got carried away and threw in a Movement Panel and a slide script which can toggle which H-Bridge is controlled by the movement panel... It doesn't allow the Forward/Reverse/Left/Right/Stop script commands to work with both, they will only work with whichever H-Bridge is enabled.

It's on the cloud.

However, that wont be needed for your rising/lowering h-bridge @TymTraveler. To raise and lower you can simply just use Set(DigitalPort, On/Off) and some timings to enable/disable the motor, basically what is used in the script manager of my example to make the forward, reverse, left, right and stop movements.
