This driver wraps two instances of the "segwayrmp" driver for use on an RMP 400 platform. This makes the RMP appear as one position interface (2d and/or 3d) to clients. It forwards requests and velocity commands to both of the underlying position2d and position3d devices. It also averages all of the odometry reported back from the underlying position2d and position3d devices.
Not sure whether it should be under "mixed" or "position" (probably mixed), so I uploaded the whole directory. Should also add a dependency on the "segwayrmp" driver, but I don't know cmake well enough yet.
It was tested before it was ported to 3.0, but should still work just fine.
