The neurotech company Neuralink, led by Elon Musk, has launched the clinical trial CONVOY, which aims to investigate whether its innovative brain implant can control a robotic arm designed to assist people with reduced mobility.
Advances in Brain-Robotic Technology
This trial includes participants from the PRIME study, in which the N1 implant and the R1 robotic system are being tested. The latter uses thin threads to record neural signals directly from the cerebral cortex. To date, two patients with spinal cord injuries have received the implant and have successfully interacted with digital devices through the power of thought.
The N1 implant acts as a translator of brain signals into commands that can operate external devices, such as a robotic arm. According to Neuralink, this technology could represent a radical shift in the quality of life for tetraplegic people by allowing them to recover a certain level of autonomy in their daily activities.

Achievements and Challenges
The first implant in a human patient was performed in January 2024. This patient was able to play chess and post on social media using only their thoughts, although later complications arose due to a partial disconnection of the device. On the other hand, a second patient, implanted in August, has used 3D design tools and played video games, although Neuralink has not revealed recent updates on their progress.
Despite these initial challenges, Neuralink continues to advance toward its ambitious goal of having more than one thousand implanted patients by 2026. The company is focused on expanding its production capacity and improving technology to integrate neural control with physical assistance devices.
With this trial, Neuralink seeks to position itself at the forefront of brain-computer interfaces, exploring new possibilities to improve the lives of those facing mobility limitations.
