Development of a Quadruped Walking Entertainment Robot with Gravitationally Decoupled Actuation -Fundamental Study of the Drive System Using a Dynamics Simulator-
Mammal-type entertainment robots are popular due to their friendly appearance,but there are few
examples of robots that walk only on their legs due to power consumption problems.In this study,we
propose a mammal-type electric quadruped robot that employs a Gravitationally Decoupled Actuation
(GDA) to enable high-speed movement while minimizing power consumption.We developed a dynamics
simulator for the robot’s design and used it to select actuators.Additionally,the effectiveness of GDA
was confirmed by calculating the torque and rotational speed of the selected actuators during walking.
