ROBI’: A prototype mobile manipulator for agricultural applications

Abstract

The design of ROBI’, a prototype mobile manipulator for agricultural applications devised following low-cost, low-weight, simplicity, flexibility and modularity requirements, is presented in this work. The mechanical design and the selection of the main components of the motion control system, including sensors and in-wheel motors, is described. The kinematic and dynamic models of the robot are also derived, with the aim to support the design of a trajectory tracking system and to make a preliminary assessment of the design choices, as well. Finally, two simulations, one specifically related to a realistic trajectory in an agricultural field, show the validity of these choices.
