| Research Abstract |
This work discusses the Vision Based Active Antenna that can detect the contact force, the stiffness of the environment, and the contact location between an insensitive elastic antenna and an environment, through the observation of the antenna's shape by a camera. We show that both the contact location and the contact force can be estimated by measuring two arbitrary points on the antenna after a pushing motion, even though the exact contact point is hidden by occlusion. By considering the geometrical relationship between the virtual (with environment) and the real (with environment) displacements of the contact point, the stiffness of the environment can also be estimated. We extend this principle to 3D environment by adding to a one-axis moment sensor. By utilizing the antenna's shape mapped into the calibration plane, the vision sensor can provide both the contact distance and a force component on the plane. The moment sensor output allows us to evaluate the force comopnent normal tothe plane.
This system can work even under a compliant object. We show that the coupling effect between vision and moment sensor depends on the implementation angle of the CCD camera.
