In this paper we present a new approach to cooperative overhead object transportation with obstacle avoidance for multi-robot systems. This approach considers situations in which there are obstacles that only pose a risk to the robots involved in the

The inverse kinematics of mobile manipulators is a challenging problem due to the high degree of kinematic redundancy added by the coupling of the mobile platform and the manipulator. Some different approaches have been proposed to solve this problem

This paper analyses the impact of parametric uncertainties of a mobile robot kinematic model on velocity and pose estimation, providing models and quantifiable knowledge about them. Most works neglect how the uncertainty regarding the robot's constru

This work proposes a method of handling the difficulties generated by sparse and noisy sensorial output from a small quantity of ultrasonic sensors in order to develop a low cost SLAM system. A pre processing step of detecting faulty sensors was impl

This paper proposes a robot path planner based on language measure, m-planner. Workspace is discretized in a occupancy grid map and we model the system by considering how events, associated to robot’s motions, take it to different cells (discrete p
