Neuralink's breakthrough lets patient control robot with thoughts

Neuralink has achieved a significant breakthrough in brain-computer interface technology by enabling an amyotrophic lateral sclerosis (ALS) patient, Nick Wray, to control a robotic arm using only his thoughts. Through an implanted brain chip, Wray was able to perform everyday tasks such as microwaving food, drinking from a cup, opening a refrigerator, and even maneuvering his wheelchair. This milestone was demonstrated during the FDA-approved “CONVOY” study, which aims to restore independence for people with severe mobility impairments by translating neural signals into Bluetooth commands that control external devices. The implant, called the N1 chip, is a small device equipped with 128 ultra-fine threads containing about 1,000 electrodes that connect directly to the brain’s surface. These electrodes detect neural activity and convert it into precise digital commands. Neuralink began human trials in 2024 after overcoming initial FDA safety concerns. Eight participants have received the implant so far, including the first recipient, Noland Arbaugh
