“…Their application in robot navigation has been less successful. Stereo systems have been reported by several groups (Inigo and Tkacik 1987;Inigo and Alley 1991;McVey, Drake, and Inigo 1986; Bruyelle and Postaire 1993; Burie and Postair 1994). However, the correspondence problem is amplified by a lack of information to characterize edges in the one-dimensional images, and our experience suggests that very accurate calibration is required.…”

“…As an alternative to the wire guided system, robots following a line painted on the floor with special chemicals have been developed. 2 Such guidance system permits relatively easy changes of the AGV path compared with the wire guidance system, yet it is still a fixed route.…”

Real-time determination of a mobile robot's position by linear scanning of a landmark

SUMMARYFor the navigation of a mobile robot, the determination of its absolute location is one of essential tasks. This paper proposes a stripe type landmark which enables us to develop a fast algorithm to calculate the distance and orientation of a camera relative to the landmark. Exact and closed form solution of the camera location is obtained from the geometric relation between the pattern of landmark and its projected image. Since the presented algorithm requires only one row of the mark image, determination of the location can be processed in real-time. In addition, the mark can be identified using the projective invariant of the original mark pattern without any additional patterns. The effect of the error sources on the location determination is analyzed through a series of simulations and experiments. The applicability of the algorithm to mobile robots is discussed using the experimental results.

I n this study a two-motion-modes mobile robot is developed. The motion of the mobile robot is controlled by three d.c. servo-motors, two of which drive two wheels independently and one of which steers the wheels simultaneously. The two motion modes of the mobile robot, different velocity motion ( D V M ) and equal velocity motion (EVM), are analysed. Kinematic and dynamic analyses of the two motion modes are performed. For the implementation of real-time control considering mobile robot dynamics, the forward and inverse dynamic solutions are derived explicitly. Through a simulation, the path-tracking and control performance of the mobile robot considering dynamics is compared with the considering kinetics only, and the possibility of real-time dynamic control is proved.
