How BrainCo robotic hands are changing lives - The Robot Report

BrainCo, a company founded in 2015 and incubated by Harvard Innovation Lab, has developed an advanced non-invasive brain-computer interface (BCI) that enables users to control prosthetic hands with remarkable dexterity. The technology notably transformed the life of Jian, a teenager who lost his right arm in an accident. Using BrainCo’s Intelligent Bionic Hand, Jian regained the ability to perform complex tasks such as rock climbing and playing the piano, restoring both his physical capabilities and his sense of hope. The company’s latest product, the Revo 2 Dexterous Hand, is a lightweight (383 g) prosthetic capable of generating a grip force of 50 newtons, allowing it to lift up to 20 kg. It features biomimetic joint optimization, precision transmission, and a 3D tactile sensing system that can perceive hardness, texture, force direction, and distance, enabling delicate tasks like lighting a match. The device operates quietly (below 50 decibels)
