Abstract: This paper proposes a muscle-like actuator inspired by the
agonist-antagonist characteristic of biological muscles. As a preliminary
study, we designed an agonist-antagonist actuator with a magnet pair as an
agonist, elastic components as an antagonist, and an electromagnetic trigger.
The mechanical properties of the magnet pair and the trigger were analyzed
using the finite element method. In the experiments to verify the feasibility
of the actuator, two types of elastic components (rubber bands and polymer
tubes with a specific structure) were respectively utilized. The effectiveness
of the actuator was confirmed by experiments.
