Detailed Description

The class modelling the motor for the attachment device of the MarXbot.

This class models the motors for the attachment device of the MarXbot. The device has two degrees of freedom: the orientation (i.e. where it is relative to the robot turret) and the status, that is whether the device is open, half-closed or closed. Regarding orientation, it is possible to control it by position or by velocity. In both cases the movement is never faster than a maximum speed (that can be changed). When the attachment device is open, it can be rotated using this motor. If it is half-closed or closed and the robot is actually attached to another robot, the motor controlling the rotation is disabled and the attachment device rotates freely. Moreover every command to the attachment device (e.g. setDesiredPosition, setDesiredVelocity...) is ignored. If instead the robot is not attached to another robot, the device behaves normally (as if the attachment device was open). Given two robots A and B, A attaches to B if the following requirements are satisfied:

the attachment device of A is in contact with the turret of B and the attachment device of B is far from the turret of A. In other words the two attachment devices must not be in contact;
the attachment device of A was in the open status in the previous timestep and is switched to half-closed or closed status in this timestep. The attachment is instantaneous (i.e. it happends in one timestep). The status of the device after the attachment determines how the two robots can move with respect to each other: if it is closed, B cannot rotate its attachment device (a fixed joint is added between the attachment device of A and the turret of B); if it is half-closed, B can rotate its attachment device with the limitation that it can collide with the attachment device of A and so a 360° rotation is not possible (a hinge is added between the attachment device of A and the turret of B). To detach, a robot simply has to change the status of its attachment device to open. This motor only works for dynamic robots. For the attachment process to be successful, both robots must be dynamical and have the attachment device enabled. If the robot attachment device is not enabled, changes to the device status are not applied
