EVALUATION

So, I have verified that after the fix we do release all memory we allocated for Robot.
So, I'm commiting this.  Will investigate in background why we still see some problems :(

EVALUATION

I've implemented disposing of native object (the same way as we do for other components)
But I still see the same problem (memory leak :( We, basically, are not receiving notification that Robot is going to be collected for very long time :(
                                     

EVALUATION

it looks like we do not delete native class associated with WRobotPeer :(
Need to implement this.
