Caenorhabditis elegans is a small worm which is approximately 1mm in length. For the reason of technological limits, it has been difficult to measure the friction between the body and environments. The present study proposes an estimation method for frictional force using locomotion information obtained from video analysis of actual worms. The results indicate that the body model driven by the estimated frictional force can trace the locomotion of the worm within 4% of the body length. The proposed method may be applied to analyze the relationship between friction and gait control.
