[Eeglablist] Simultaneous recording of EEG and Robot motion

[Makoto Miyakoshi]

Dear Sanjaya,

Hmm that's a difficult question.
Probably you can test it step by step. For example, while touching the
robot with a rubber hand vs. bare hand, or using wood stick vs. rubber
stick vs. conductive stick, or touch, close but no touch, no touch far,
etc. I'm sure the artifact level is highest when subject's body touches the
robot. Could there be any non-conductive material between a subject and and
the robot to prevent the artifact from contaminating EEG?
