Fig. 1From: Studying animal locomotion with multiple data loggers: quantifying time drift between tagsPictures of multiple tags during each experimental set up. During robotic experiments (A) multiple tags were affixed to a rigid metal rod and simultaneously moved sinusoidally in heave and pitch to provide known a input movement pattern to all tags using a robotic flapping mechanism. Multiple tags were additionally attached along the body onto live animals including a smooth dogfish (B), white sucker (C) and sea lamprey (D)Back to article page
