From the Neural Systems Group at the University of Washington:
We have developed a non-invasive brain-computer interface (BCI) that allows a user to command a humanoid robot to pick up objects and bring it to specific locations. A humanoid robot can use sophisticated robotics and computer vision techniques to explore the environment, discover possible objects and interactions, and interact with the objects selected by a user. In this way, a simple BCI-based selection interface can enable a user to perform significantly complex actions.
It seems impressive to be able to control so many complex robotic movements using brain-computer interface alone. Unfortunately my understanding is that the BCI is only used to decide which of the two blocks the robot should pick up. This is done through a scanning program similar to one-switch scanning.
Further information about the processes involved are available on their website.
