Abstract:
An apparatus and a method for measuring inertia by using a slope sensor and an angular velocity sensor for a humanoid biped walking robot are provided to facilitate expansion of a system by minimizing an additional interconnection through using controller area network communication. An apparatus(100) for measuring inertia by using a slope sensor and an angular velocity sensor for a humanoid biped walking robot comprises a slope sensor(120) and angular velocity sensors(130,131). The slope sensor measures a slope of a robot relative to the gravity. The angular velocity sensors measure angular velocity of the robot relative to the gravity. A complementary filter receives and filters the slope and angular velocity signals measured in realtime by the slope and angular velocity sensors. A digital signal processor is connected to the complementary filter to perform A/D conversion relative to the slope and angular velocity signals.
