Mobile manipulators extend the workspace of manipulators by mounting them on mobile platforms. The paper presents the design of a motion controller for a mobile manipulator. The mobile manipulator consists of a mobile platform driven by Mecanum wheels and a robotic arm with 6 degrees of freedom. A Mecanum wheeled platform provides 3 degrees of freedom in motion. Such a platform is usually driven by...
This paper presents an approach to estimate the energy consumption of an omnidirectional Automated Guided Vehicle (AGV) equipped with four Mecanum wheels for any given trajectory. We derive an energy model for such a robot using experimental data, and perform the estimation by applying the trajectory's translational and rotational velocity profiles to it. These profiles are given as the output of...
Localization of transport vehicles is an important issue for many intralogistics applications. The paper presents an inexpensive solution for indoor localization of vehicles. Global localization is realized by detection of RFID transponders, which are integrated in the floor. The paper presents a novel algorithm for fusing RFID readings with odometry using Constraint Kalman filtering. The paper presents...
This paper presents a new approach for kinodynamic online motion planning for Automated Guided Vehicles (AGVs) in industrial environments. AGVs normally transport large and heavy transport units such as Euro-pallets or mesh pallets. Nowadays just-in-time inventory management and lean production requires the transport of small transportation units. Thus a flexible material flow is needed that can not...
Over the last years a number of different vehicle controllers has been proposed for tracking planned paths or trajectories. Most of previously published works do not compare their results with other approaches or limit the comparison to a few scenarios. Unfortunately, comparisons with existing controller concepts are very rare and a ranking is hard to establish from the literature. In this work, we...
