Flying Fish Picked Off From Above And Below | The Hunt | BBC Earth

Flying fish can make powerful, self-propelled leaps out of water into air, where their long, wing-like fins enable gliding flight for considerable distances. It appears these Flying Fish are in a no win situation, picked off above the surface by Frigatebird's and devoured underwater by the Dorado.

Rapid, Dynamic Obstacle Avoidance with an Event-based Camera

In this work, we study the effects that perception latency has on the maximum speed a robot can reach to safely navigate through an unknown cluttered environment. We provide a general analysis that can serve as a baseline for future quantitative reasoning for design trade-offs in autonomous robot navigation. We consider the case where the robot is modeled as a linear second-order system with bounded input and navigates through static obstacles. Also, we focus on a scenario where the robot wants to reach a target destination in as little time as possible, and therefore cannot change its longitudinal velocity to avoid obstacles. We show how the maximum latency that the robot can tolerate to guarantee safety is related to the desired speed, the range of its sensing pipeline, and the actuation limitations of the platform (i.e., the maximum acceleration it can produce). As a particular case study, we compare monocular and stereo frame-based cameras against novel, low-latency sensors, such as event cameras, in the case of quadrotor flight. To validate our analysis, we conduct experiments on a quadrotor platform equipped with an event camera to detect and avoid obstacles thrown towards the robot. To the best of our knowledge, this is the first theoretical work in which perception and actuation limitations are jointly considered to study the performance of a robotic platform in high-speed navigation.

Design and Fabrication of a Soft Robotic Hand and Arm System

We present the hardware design and fabrication of a soft arm and hand for physical human-robot interaction. The six DOF arm has two air-filled force sensing modules which passively absorb impact and provide contact force feedback. The arm has an inflated outer cover which encloses the arm’s underlying mechanisms and force sensing modules. An internal projector projects a display on the inside of the cover which is visible from the outside. On the end of the arm is a 3D printed hand with air-filled, force sensing fingertips. We validate the efficacy of the outer cover design by bending the arm to reach out and grasp an object. The outer cover performs as intended, providing enough volume and range of motion for the arm to move, and stretching at the elastic relief features in the cover. We also validate the hand design by implementing a grasping algorithm in which the fingers follow a closing trajectory, make contact, then maintain a given range of fingertip pressure. Using this algorithm, the hand is able to gently grasp a soft object.

Watch the Coast Guard Capture Another Narco Sub With $69 Million in Cocaine

The Coast Guard intercepted a makeshift narco-submarine hauling a hell of a lot of cocaine in the Pacific Ocean.

The Coast Guard said Thursday that its cutter ship the Harriet Lane seized some 5,000 pounds of the drug off the semi-submersible vessel manned by four suspected smugglers on October 23.

A boarding team was able to take control of the narco-sub before the people onboard could use a system designed the sink the craft, the Coast Guard said.

The Conservation of The Assassination of Archimedes ASMR Version

Julian Baumgartner of Baumgartner Fine Art Restoration in Chicago works to conserve this painting of the assassination of Archimedes.  Obscured by a darkened varnish and mounted to a wood panel the artwork is cleaned and the panel removed using both modern and traditional techniques.  Using routers, hand planes and scalpels the wood is painstakingly removed form the thin paper in order to facilitate the preservation of the paper via archival mounting to acid-free board.

Employing archival and reversible materials and techniques, Baumgartner ensures that the piece is preserved and stable for generations to come.

**** Note: I mistakenly refer to the painting as "The Assassination of Aristotle" when in fact the poor chap about to part with his head is Archimedes.  **** https://instagram.com/baumgartnerrest... https://facebook.com/baumgartnerfinea... http://bfar.com

How These Prosthetics Make Everyday Tasks Easier

Naked Prosthetics custom-makes prosthetics that help give amputees motor function and protection. Specifically developed for those with finger loss, these prosthetics mimic natural finger motion by working in cohesion with the remaining fingers. Naked Prosthetics makes the fingers through a combination of 3D printing and machinery.

Rusty Deadlocked Vice - Perfect Restoration

Broken Vise Restoration - Gressel SwitBroken Vice Restoration - Gressel Switzerland.

In this video i'm restoring a broken swiss vice.

Like, comment, subscribe.

I bought this vice from a friend for 20$. It was super rusty and dirty, one part was missing, two screws were broken off and the movable jaw was completely stuck. Gressel is very well known in switzerland for making very good, if not the best vices. That fact made it absolutely worth to restore it. They still produce this type of vice today, they just made some very small changes over the years. I found out that they built their vices in this style until 1991. So it's at least 27 years old. It had the rough jaws on, but you could always choose if you want them with rough or flat jaws when you buy a new one. I'm not a fan at all of the rough jaws, because they ruin every surface of clamped pieces. So I decided to put flat jaws on. I still restored the rough ones and I'm going to keep them. I restored this vice for myself.
