“…In the MMRS, standard patterns are placed along the edges of the path network. Each robot is equipped with a rotary optical encoder [28] and a standard pattern detector. Rotary optical encoders detect the rotational displacement of the measured wheels and calculate the displacement of the robot for short periods.…”

“…The advantage of using both optical encoders and standard patterns lies in their ability to work together as a unique error correction scheme. Standard patterns are placed at distances of 50 m since rotary optical encoders are accurate up to this distance [28]. Using the above method of position determination and verification greatly reduces the number of standard patterns and makes the system more flexible, since the robot is less dependent on changes in the environment.…”

In this paper, a systematic method for kinematics and dynamic tricycle modelling of AGV is presented to track the desired trajectory. The localization of AGV is done by a laser sensor NAV200 which is used to detect the AGV position in dour environment in real time. The AGV consists of 2 passive wheels at rear and 1 driving wheel at front. The navigation system for tricycle AGV is based on front wheel, i.e., the movement of AGV is controlled by front wheel. In order to move the AGV, kinematic model used here is a constant velocity model for linear motion and pure pursuit algorithm is used so that AGV follows the desired trajectory. The experimental result shows that AGV successfully tracks the predefined path in real environment.

“…This typically involves the laying of cables [27], the painting of stripes, using magnetic markers [23], the placement of retro-reflective landmarks [10] or infrared beacons [13]. In other cases, almost complete reliance on highly accurate dead reckoning systems is required [17]. World modeling is generally kept to a minimum as travel is usually severely restricted within the workspace.…”

Flexible manufacturing systems (FMS) that incorporate transport robots are currently dominated by the use of automatic guided vehicles. These AGVs generally require significant restructuring of the workplace in order for them to be useful. The concept of flexibility in manufacturing is somewhat compromised by this strategy.Our previous work in mobile robots, resulting in the Autonomous Robot Architecture (AURA), is applied to the manufacturing domain. This approach, contrary to the AGV methodology, embeds significant amounts of knowledge (both environmental and behavioral) to ultimately give a mobile robot far greater latitude in interacting with its environment.This paper presents the motivation and subsequent simulation studies that demonstrate the feasibility of migrating schema-based navigation into an FMS. In particular, the creation of a docking motor schema to accomplish interaction with the workplace is detailed.
