Automated Droplet Manipulation Using Closed-Loop Axisymmetric Drop Shape Analysis

Automated Droplet Manipulation Using Closed-Loop Axisymmetric Drop Shape Analysis.

Droplet manipulation plays an important role in a wide range of scientific and industrial applications, such as synthesis of thin-film materials, control of interfacial reactions, and operation of digital microfluidics. Compared to micron-sized droplets, which are commonly considered as spherical beads, millimeter-sized droplets are generally deformable by gravity, thus introducing nonlinearity...

Closed-Loop Distributed Manipulation Using Dis rete A tuator Arrays

Closed-loop, ultraprecise, automated craniotomies.

A large array of neuroscientific techniques, including in vivo electrophysiology, two-photon imaging, optogenetics, lesions, and microdialysis, require access to the brain through the skull. Ideally, the necessary craniotomies could be performed in a repeatable and automated fashion, without damaging the underlying brain tissue. Here we report that when drilling through the skull a stereotypica...

Closed-loop Visual Grasping and Manipulation

Sensors play an important role in providing feedback to robotic control systems. Vision can be an eeective sensing modality due to its speed, low cost, and ex-ibility. It can also serve as an external sensor that can provide control information for devices that lack internal sensing. Many robot grippers do not have internal sensors. These grippers can be prone to error as they operate under ope...

Distance protection closed-loop testing using RTDS

This paper presents a distance protection test procedure by applying the Real-Time Digital Simulator (RTDS) of a power system. RTDS is a tool to design, develop, and test power-system protection. The RTDS enables real-time computation of electromagnetic phenomena with a calculation time step of even 50μs. The hardware allows the import and export of many signals from the simulator to an ext...
