An Imperial-Tsinghua BCI lets ten healthy people control a pair of extra robotic arms while balancing a ball with their own hands
Tianyu Jia and Dario Farina at Imperial College London, with collaborators at Tsinghua University and Southeast University Nanjing, published a Nature Communications paper on 2 July 2026 describing a tactile-encoded non-invasive BCI in which ten healthy participants controlled four supernumerary robotic degrees of freedom concurrently with a bimanual ball-balancing task, reaching 74.79 per cent single-task and 59.69 per cent dual-task online accuracy after three days of training.
