Brain-computer interfaces (BCIs) use recorded brain signals to bypass the musculoskeletal system by directly controlling a computer. In a collaboration with the CONQUER CollabOrative we are developing a BCI to control a miniature robot, the DARwIn-OP.
We are looking at changes in blood flow in different areas of the motor cortex during hand and foot motor imagery (imagined movements). The imagined movements are mapped to high-level navigation control for a robot and used to navigate a small room towards a goal area. Future applications of this project could be control of tele-presence or assistive robots as well as prosthetic limbs.
