Drone Collision Recovery System

Prof. Konstantinos Karydis’ lab at the University of California, Riverside has developed a new active resilient quadrotor (ARQ), which incorporates passive springs within its frame to absorb shocks and survive collisions.  Each arm of the quadrotor is equipped with sensors to accurately and rapidly detect the location (in the drone’s frame) and intensity of a collision.  In addition, a recovery controller that enables the drone to sustain flight after collision with objects like wall, poles, or moving objects. The technology has been proven on the quadrotor however it may be applied to drones with more than four arms. Fig 1: Instances of the novel ARQ drone detecting and recovering from colllisions in (a) and (b) and from collision with a wall (c) and (d). Fig 2: shows ARQ detecting and recovering from a passive collision. (a) ARQ hovers. (b) Collision starts and the ARQ arm absorbs the shock. (c) recovery control starts and there is a body interfering with the ARQ’s flight path. (d) ARQ is stabilized and hovering again.  

Bioengineered Wnt5a Therapeutics For Advanced Cancers

Researchers at the University of California, Davis have developed RNA-based therapeutics to treat Wnt5A-expressing cancers, including treatment-resistant prostate cancer.
