  The use of cubesat swarms is being proposed for different missions where
cooperation between satellites is required. Commonly, the cube swarm requires
formation flight and even rendezvous and docking, which are very challenging
tasks since they required more energy and the use of advanced guidance,
navigation and control techniques. In this paper, we propose the use of an
extensible hook system to mitigate these drawbacks,i.e. it allows to save fuel
and reduce the system complexity by including techniques that have been
previously demonstrated on Earth. This system is based on a scissor boom
structure, which could reach up to five meters for a 4U dimension, including
three degrees of freedom to place the end effector at any pose within the
system workspace. We simulated the dynamic behaviour of a cubesat with the
proposed system, demonstrating the required power for a 16U cubesat equipped
with one extensible hook system is considered acceptable according to the
current state of the art actuators.
