The Advanced Grabbing Unit Junior (AGU Jr.), is a small-sized docking device which can couple to any surface without the requirement of another docking device on the target to mate with. This is a virtual necessity for redirecting asteroids or comets, though the AGU can be used to grab onto much more than just asteroids. In fact, it can grab just about anything, even Kerbals.
It is a smaller (and lighter) version of the Advanced Grabbing Unit, with a 0.625m attachment node below. This also means that it is easier for it (the Jr, rather than the regular grabbing unit) to grab onto smaller objects, such as floating 1.25m parts frequently appearing in rescue missions.

Use
The AGU ('claw') can be used to connect (dock) your craft to various objects, such as other craft, debris, asteroids and even Kerbals.
Objects connected by claws are controlled together as a single entity. It's like a docking port, but without the complexity of aligning with a receiving port on the target.
Unlike docking ports, AGU by default does not allow the transfer of resources (liquid fuel, electricity, etc.). This can be changed in the difficulty settings of your save.[1].
Kerbals grabbed by the AGU's claw will go limp in a ragdoll state and can be carried with the craft.
Note that when a target vessel is captured with a klaw, the combined vessel usually gets a new "Control from Here" point. That point is almost never pointing in the same direction as the previous control point, which means that all the navigational targeting will suddenly be "off". Make sure to reset your "Control from Here" point after every single klaw docking, or your ship will be thrusting in very surprising directions.
Operation
.png)
Operation is simple. Claws state toggles between Armed or Disarmed. While disarmed, it behaves like any other part. Once armed, approach perpendicularly to the target surface at no more than a few m/s and the extended claw will automatically grab anything it collides with (or that collides with it), docking the target to the current vessel.[2] To undock from the target, right-click the AGU and choose Release.
Once the AGU is attached, its claw's pivot can be toggled. The pivot is locked whenever armed and not attached, but can then be unlocked by right-clicking the AGU and choosing Free Pivot.
While freed, reaction wheels or RCS can be used to alter the craft's pitch and yaw (from the AGU's perspective) relative to the target, but not roll, the claw turns, not twists. This is vital when attached to asteroids, as thrust must be aimed directly at the center of mass to keep the asteroid under control while moving it.
Note that controls may feel reversed; the opposite end of the craft from the claw will be moving. Note also that the range of motion the pivot provides is bounded by a circle, like the AGU itself, essentially drawing a conical area.
After aligning the craft, the Lock Pivot command can be used to fix the craft's orientation relative to the grabbed target. Note that even when locked, with sufficient lateral force the pivot can be bent, though once the force is removed it will bend back to its locked orientation.
Grabbing a Kerbal
Although tricky, possible to dock to a Kerbal. The Kerbal must be touched with the exact center of the extended claw in order to capture; touching the Kerbal to the claw arms has no effect.
The AGU will not close around the Kerbal. Rather, it will simply indicate that it has docked with something, and the Kerbal will be locked in place while still free to ragdoll.
The easiest way to grab a Kerbal is to use the Kerbal's own jetpack to steer into the exact center of the claw.
When docked successfully, your controls will change to the ship's controls, and the option to EVA with that Kerbal will not be available until the AGU is released.
The same Kerbal-AGU system can safely withstand reentry with adequate deceleration to landing velocity.
Trivia
- It is possible the name "Klaw" is a reference to "Toy Story".
- In previous versions it was necessary to disarm the klaw to reset it after each use. This no longer seems to be required.
- It used to be possible to “Disarm” the AGU while attached without releasing it − a merely visual effect.
- [Needs confirmation for current version] There is a bug in version 1.1.3 that sometimes resets the "Control from Here" point when you switch focus to the craft, and sometimes when you activate the navball in map mode.
