Tekkotsu: MotionManager Class Reference

Since Main and Motion run as separate processes, they could potentially try to access the same motion command at the same time, leading to unpredictable behavior. The MotionManager enforces a set of locks to serialize access to the MotionCommands. Although you could call checkoutMotion() and checkinMotion() directly, it is instead recommended to use MMAccessor to automatically handle casting and checkin for you.

The other problem is that we are sharing the memory holding MotionCommands between processes. MotionManager will do the necessary magic behind the scenes to distribute new MotionCommands to all the involved processes (currently just Main and Motion)
You can create and add a new motion in one line:

  // type A: prunable motions are automatically removed when completed:
  motman->addPrunableMotion( SharedObject<YourMC>([arg1,...]) [, priority ] );

  // type B: persistent motions are removed only when you explicitly request it:
  MC_ID id = motman->addPersistentMotion( SharedObject<YourMC>([arg1,...]) [, priority ] );
  // then later: motman->removeMotion(id);

If you want to do some more initializations not handled by the MotionCommand's constructor (the arg1, arg2, ... params) then you would want to do something like the following:

Notice that yourmc is actually of type SharedObject, but you're calling YourMC's functions on it through the '->' operator... SharedObject is a "smart pointer" which will pass your function calls on to the underlying templated type. Isn't C++ great? :)

bool MotionManager::updatePIDs ( OPrimitiveID primIDs[NumOutputs] )

call this when you want MotionManager to update modified PID values, returns true if changes made (only MotoObj should be calling this...), see PIDMC for general PID documentation

This function handles the conversion from the Tekkotsu format (one regular IEEE float per parameter, to the OPEN-R format (which takes a specialized, reduced precision floating point number) This is all documented in PIDMC as well.

In order to send Tekkotsu's PIDs to the system, they are converted to the gain/shift format. On the ERS-2xx, we could dynamically choose shift values to allow more precision in setting values.

With the ERS-7, all shifts are shared, so they must be set to a common set of values, defined by WorldState::DefaultPIDShifts. This limits the range of gains which can then be set.

Due to the mysterious warning which would occur with the 2xx, (AGRMSDriver::SetGain() : 0x0A IS USED FOR GAIN SHIFT VALUE.) and since this seems to be the way things are going, all models now, by default, use global shift values (which can vary from model to model, just global for each model)

You can revert to the dynamic shift selection by commenting-in the noted code section below.

A final note: the OPENR::SetJointGain function seems to be a rather costly function call. You should probably try to avoid setting PIDs at too high a frequency.

Definition at line 567 of file MotionManager.cc.

void MotionManager::updateWorldState ( )
