A second area where BCI technology can support motor substitution is in assisting user's mobility, either directly through brain-controlled wheelchairs (e.g., Millán et al., 2009) or by mentally driving a telepresence mobile robot – equipped with sensors for obstacle detection as well as with a camera and a screen – to join relatives and friends located elsewhere and participate in their activities (Tonin et al., 2010). Several commercial platforms already exist for allowing this kind of interaction: e.g., peoplebot (Mobile Robots Inc., Amherst, USA), iRobot (iRobot Corp., Bedford, USA), robotino (Festo AG, Dietikon, Switzerland).
