Brainobot

Brainobot is a biohybrid robot system in which a 3-month-old human cortical brain organoid serves as the decision layer of a ROBOTIS humanoid robot.

Highlights

• Team: Indiana University's Brainoware group
• Hardware: organoid on a MaxOne high-density microelectrode array (MEA) for recording and stimulation
• Tasks: grasping, chasing a laser dot, ~92–94% accuracy
• Publication: bioRxiv preprint (Sep 15), not yet peer reviewed

Why it trended

On Oct 24 it hit X News as "Human Brain Cells Now Power Robots and Prototype Data Centers", sparking debate on organoid intelligence (OI) and ethics.

Who should follow it

• Researchers in organoid intelligence, BCI and neuromorphic computing
• Readers interested in AI ethics and biocomputing
