One of the coolest things I ran across at DSEI is the Magnetic Drop Release System. Developed by the UK’s Shadow Concepts and sold by sUAS maker Skydio, the MDRS is a purpose built, magnetically actuated, end effector release system which integrates into Skydio XD10 quadcopters. This is particularly interesting for US forces who have adopted the Skydio system, which is on the Blue UAS list, for use at the Squad level. Currently, units are home brewing their own release systems for munitions.

Like those unit built systems, MDRS is 3D printed, but they use a much higher fidelity printer than is found in most workshops making it more durable and the novel magnetic release system offers consistent reliable payload retention during flight and release of ordnance precisely where you want it. It even maintains full holding force even if the drone loses power. MDRS only draws a momentary charge the moment you intentionally release the payload.

Additionally, there are several ways to attach the payload, including the MOLLE Plate Basket.
Shadow Concepts is working to adapt MDRS to other drones.
