Modern high-dexterity prosthetics are quite pricey to say the least, but engineers at MIT and Shanghai Jiao Tong University hope to change that. The team has built a soft, lightweight and potentially inexpensive neuroprosthetic hand that allows amputees to easily perform everyday activities, such as picking up a glass, pouring a carton of juice, petting a dog, or simply zipping up a backpack.

It currently costs only $500 to build this inflatable smart hand, which is not only soft but also very elastic. The prosthesis has a tactile feedback system capable of restoring primitive sensation in a volunteer’s residual limb. Despite being lightweight, it is still remarkably durable and able to recover quickly after being hit with a hammer or run over by a car.
DJI FPV Combo – First-Person View Drone UAV Quadcopter w/ 4K Camera, S-flight Mode, Super Wide 150° FOV, Low Latency HD Transmission, Emergency Braking & Hovering, Gray IMMERSIVE FLIGHT EXPERIENCE: Feel the thrill of an immersive flight offered by the DJI FPV Goggles V2 and DJI FPV’s super-wide 150° FOV, giving you an ultra-smooth, real-time view of your flight.4K/60FPS VIDEO: The DJI FPV aircraft can record 4K/60fps video at up to 120Mbps, delivering sharp details are captured making the footage look as exciting as the flight.BRAND NEW S MODE: Easily get the dynamic look of FPV footage in S mode. This hybrid flight mode combines the freedom of manual flying with the simplified controls of previous DJI drones. ADVANCED SAFETY FEATURES: An additional bottom light, Smart Return to Home (RTH), Low Battery RTH and forward and downward obstacle detection are all integrated into DJI FPV ensures safe flight even at high speeds.OCUSYNC 3.0 TRANSMISSION SYSTEM: Enjoy crystal clear realtime and HD Low-Latency Transmission video even at distances up to 10.2 miles.
This is not a product yet, but the performance is already comparable or superior to existing neuroprostheses, which we are excited about. There is enormous potential to make this soft prosthesis very cheaply, for low-income families who have suffered from amputations,” said Xuanhe Zhao, a professor of mechanical and civil and environmental engineering at MIT.
