WALKER TRACKING DEVICE, AND WALKING SUPPORT AND CARRYING DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a walker tracking device capable of tracking along the walk track. SOLUTION: The device is equipped with: a tracking data derivation part 23 for deriving the tracking data (xif, yif) indicating a relative position coordinates of the walk track from a camera image; an encoder data collecting part 24 for collecting the encoder data (xi, yi,θi) expressing the position coordinates of a move object and direction to absolute space by an encoder 16 while resetting origin of the coordinates for each of the halt operation; a tracking/halt period management part 25 for intermittently setting up the tracking period and managing time so that the tracking period and the halt period are alternatively iterated; a tracking data calculation part 26 for calculating the tracking data in a next occasion based on the tracking data and the encoder data when the halt period comes; and a drive signal output part 29 for outputting the drive signal based on tracking data in the next occasion when the tracking period comes. By executing control for the tracking period in the next occasion by the tracking data in the next occasion acquired during the halt period, the intermittent tracking operation is executed.
