Скачать или смотреть Separating "Branches" - Asymmetric Loads

If a drone needs to examine a tree, branches can block sensors and tangle in rotors. To avoid this hazard, the drone needs to be able to push away such obstacles. Here we see a branch-spreading system in action, pushing bars apart to peer through. Note that each bar is held by an elastic band, producing a resisting force. In this test, these bands are asymmetric, producing offset forces which the aircraft must account for during its interaction with the branches.

This work was conducted by Pedro Mendes as part of his Doctoral research at the University of Auckland.
