Esper Hand | The most advanced prosthetic arm with "human-like dexterity"

Esper Bionics has developed a prosthetic arm with intuitive self-learning technology that can predict intended movement faster than similar prosthetics. Watch on YouTube

Esper Hand uses an electromyography-based brain-computer interface (BCI) a computer-based technology system that gathers brain activity or information to trigger movement.When the wearer wants to control the hand, their brain sends impulses to specific muscles to activate them.

Over 30 non-invasive sensors that connect the stump socket to the wearer's skin pick up on this muscle activity or "electrical cues" and relay the information to trigger an action in the hand. BCIs are often used by paralysis patients to control machines with just their thoughts. 

Esper Hand has five movable digits and can rotate and grip in multiple ways, allowing the wearer to perform everyday tasks such as opening a bottle, driving a car, using kitchen utensils or tapping a phone screen. The 380-gram arm is made from a combination of polyoxymethylene plastic, fluoroplastics, nylon, aluminium, steel, titan, bronze and three types different types of silicone. It comes in four sizes and five colours.

Scientists Create a Wearable Sensor for Plant Leaves to Detect Water Loss Early

Image
Plants can't speak up when they are thirsty. And visual signs, such as shriveling or browning leaves, don't start until it's too late. Metal electrodes have previously been used to monitor thirsty plants, but it's difficult attaching these devices to hairy leaves, which reduces their accuracy. Now, researchers reporting in ACS Applied Materials & Interfaces have created a wearable sensor for leaves that stays put, and makes it easy to remotely manage plants' water stress. Wearable devices for people are so sophisticated that some smart watches monitor the electrical activity of the wearer's heart, using electrodes that sit against the skin, and send the data to websites, which allow physicians to monitor and assess their patients from a distance. Similarly, plant-wearable devices could help farmers and gardeners remotely monitor plant health, including leaf water content – a key marker of metabolism and drought stress. Renato Lima and colleagues wanted to id

MX-Phoenix | The tarantula-inspired robot was built by one man in his garage

Image
Norwegian engineer Kåre Halvorsen has created the MX-Phoenix, a 3D printed spider inspired hexapod robot that uses 18 different motors to crawl over uneven ground. Zenta has designed a number of hexapods and other varieties of robots over the years, including his award-winning MorpHex robots. He states his goals for this particular project: “A more dynamic gait engine and terrain adaptation. I also want a hexapod robot with a relative small body and large leg section, I’m also trying to keep the total weight as low as possible.” The robot’s tibia and body components were designed using Fusion 360 and printed on a Wanhao Duplicator i3. He then strengthened the printed ABS parts using an acetone vapor treatment. Weighing 4.76 kg (10.5 lb), the Mx-Phoenix utilizes a total of 18 Dynamixel servos from Robotis. The C++ code, which contains Zenta’s custom gait-algorithm for hexapod robots (called DynaZgait), is being run on a Teensy 3.6 MCU. The idea to design a hexapod walking robot was deve

DRAGON | A Japanese dragon drone moves independently through the air, resembling the sinuous motion of a flying snake

Image
 The JSK Lab at the University of Tokyo has introduced a cutting-edge drone known as the "dragon drone," which is composed of multiple small drones capable of dynamic transformations. According to reports, this drone not only has the ability to alter its shape into various forms like squares or curved lines but also possesses the capability to autonomously determine the most suitable shape based on the space it needs to navigate. The acronym "DRAGON" stands for "Dual-rotor embedded multilink Robot with the Ability of multi-deGree-of-freedom aerial transformatiON." Inspired by traditional dragon kites, the design features a tail composed of interconnected smaller kites.  Watch on YouTube Each of the small drones is equipped with a pair of ducted fans that can be adjusted to direct thrust in almost any direction. Powered by an Intel Euclid dev kit and supported by a spine-mounted battery pack offering three minutes of flight time, the DRAGON drone's modu
