Fig. 5: Model evaluation of the arm’s shape estimation.
From: A dexterous and compliant aerial continuum manipulator for cluttered and constrained environments

“EST” denotes estimates and “COM” denotes center of mass. “deg” means degrees. τarm denotes arm’s shifting moment. a Single section’s shape estimation. b Multiple sections' shape estimation. c Illustration of arm’s COM in simulation. d Evaluation of arm’s COM in actual motions.
