The recent advances in state estimation, perception, and navigation algorithms have significantly contributed to the ubiquitous use of quadrotors for inspection, mapping, and aerial imaging. To further increase the versatility of quadrotors, recent works investigated the use of an adaptive morphology, which consists of modifying the shape of the vehicle during flight to suit a specific task or environment. However, these works either increase the complexity of the platform or decrease its controllability.

In this work, we propose a novel, simpler, yet effective morphing design for quadrotors consisting of a frame with four independently rotating arms that fold around the main frame. To guarantee stable flight at all times, we exploit an optimal control strategy that adapts on the ...

The present application relates to precision mechanical tools, and more particularly to a combination tool for tensioning a fastener, for example as done when truing and aligning a tension-spoked wheel.

Many precision assembly operations require measuring the amount of tensile strain applied to fasteners. For example, in the fabrication of engines and pressure vessels, stretch bolts need to be torqued while measuring the amount of bolt stretch to ensure tensile strain on the fastener is within specification. For threaded fasteners, precision fastening entails a cumbersome two-part process: first, the bolts are torqued to a certain specification and then, the tensile strain of the fastener is measured. This process is repeated until the manufacturing specs are achieved for each fastener.

Able Innovations’ mission is to improve healthcare outcomes and people’s quality of life by developing innovative assistive technologies. Our first innovation is a transfer robot that can lift, move, and place humans in a fully automated manner with zero-physical effort from caregivers.

Our innovation moves objects similarly to a standard conveyor belt, but unique design considerations must be made to ensure the product is capable of performing fully-automated transfers of individuals in a safe, efficient, and dignified manner.

To do so, we are developing a unique biocompatible material for the conveyor belt surface, as well as an intricate sensory system to ensure a tolerable level of force is exerted on the individual being transferred, and that there is no ...
