Title:
IMAGE ACQUISITION DEVICE AND ROBOT DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/056087
Kind Code:
A1
Abstract:
An image pickup element (40) is provided to a first link (20a), i.e., a base end portion of a multijoint arm, and a lens unit (30) and the image pickup element (40) are connected to each other via a fiber cable (50) wherein image fibers are bundled. Consequently, it is not needed to provide the image pickup element at a leading end portion of the multijoint arm, and weight reduction of the leading end portion can be achieved. Furthermore, it is preferable to use a liquid lens as the lens unit (30), and to provide, in parallel to the image fibers, a power supply line for adjusting the focal point distance of the liquid lens. In such case, the focal point distance of the liquid lens can be adjusted by applying a voltage to the liquid lens via the power supply line.
