  If the grounds on the input/output side are all connected, you could always split out the signal wires on the pan/tilt and connect those to the gimbal ports and then plug the 5V/GND into the output that is powered by an external BEC.

  Hey guys, might be getting a E-Revo in the near future, can it be converted to ArduRover usage? i.e does it have the space ? Or do I have to add stacks to add the APM?

  Hi Austin,
  
  i would try the new version.

  2.4 has a lot of enhancements and should work way better although the release is not fully tested yet.
  
  look here for more information.

  Anyone have thoughts on how John Moore's plan might worth wrt momentary toggle functions like waypoint marking in learning mode?

  All out code base predate the .pde to .ino extension change
  There is no content change for a .pde vs .ino file
  They simply chose to change the default extension name, but we chose to stay with the .pde (for now)
  The "new" IDE will try to change the file names, but we ignore that. The extension name change has nothing to do with why we require the more recent IDE versions, that extension change is immaterial to us. Hope this helps.

  Gregory, There is a new user manual wiki being created currently. The Rover section will need lot's contributions from the members of this group for sure. Stay tuned, an announcement will be made once the basic structure is in place.

  I personally think the rovers will be a huge part of all this business!

  Gregory - 

  A slight alternative to option 1 would be using a motor controller that can parse the signal to differential. The Sabertooth series do this (check out the datasheet) - although the biggest they have is 60 amps I think.

  And I don't know much about CAN messages  in relation to arduinos in general, but modifying the firmware is going to be tricky. There is no easy place to step into the code and make the kinds of modifications you're talking about, I believe.

  Hi Tom,

  After we finished up our dev call on Friday I did a bunch more work on the sonar code, and added support for both inverted and hyperbolic sonars.

  The key is a new parameter SONAR_FUNCTION, which has this explanation in the code:

      // @Param: FUNCTION
      // @DisplayName: Sonar function
      // @Description: Control over what function is used to calculate distance. For a linear function, the distance is (voltage-offset)*scaling. For a inverted function the distance is ((5.0-voltage)-offset)*scaling. For a hyperbolic function the distance is scaling/(voltage-offset). The functions return the distance in meters.
      // @Values: 0:Linear,1:Inverted,2:Hyperbolic
      AP_GROUPINFO("FUNCTION",  3, AP_RangeFinder_analog, _function, 0),
  
  

  I think that should work for your Sharp 2D12 sensor, but please test it! If needed we can add more SONAR_FUNCTION values for different mappings between voltage and range.

  Cheers, Tridge
