The Parrot Bebop 2 Talon is a mountable mechanical claw for the Bebop 2 Drone.  

Using a spring lock, The Parrot Bebop 2 Talon snaps closed around an item upon contact.It can also be set to open with an integrated spring lock system. The talon is printed with minimal supports and light post-print clean up, and it is easily assembled with readily available springs, screws, washers, and nuts.

If following recommended print settings (.15mm to .2mm layer thickness, .15 % infill) the fully assembled Talon weighs just 35 grams and can pick up items several times its weight.  The Talon mounts to the Parrot Bebop 2 underbody UAM (a modified version of Kirby Downey’s Bebop 2 Drone Bottom Mount, https://www.myminifactory.com/object/bebop-2-drone-template-17450).  

Also included in this package is the Parrot Bebop 2 underbody UAM counterbalance mount, which has a location to place up to 10 US pennies to counterbalance the drone depending on load requirements
