In order to move safely and accurately, mobile platforms using steerable wheels require adequate coordination of their actuators. One possibility to achieve actuator coordination is to control the motion of the chassis’ instantaneous centre of rotation (ICR) and motion around it. Considering the chassis as a rigid body, the ICR is located at the in...

Wire EDM is a time consuming process which requires several, (cost significant), consumables like wire, filters or deionization resin. Based on machining history and sensor inputs a developed model, e.g. an intelligent software, allows to predict the status & future capacity of consumables and wear parts and thus avoid down-times of machine. The us...

Robots are usually built using stiff actuators that can provide impressive motion performances. However, they struggle to control the force, they do not handle collisions graciously and are generally bad at interacting significantly with partially unknown or kinematically constrained environments. One solution is to add a force sensor in the closed...

Omnidirectional mobile robots, i.e., robots that can move in any direction without changing their orientation, offer better manoeuvrability in natural environments. Modeling the kinematics of such robots is a challenging problem and different approaches have been investigated. One of the best approaches for a nonholonomic robot is to model the robo...

Today's robotic systems are mostly rigid and position-controlled machines designed to operate in structured environments. To extend their application domains to partially unknown, dynamic, or anthropic environments, improved physical-interaction capabilities are required.

Redundantly actuated mobile robots using conventional wheels need a precise coordination of their actuators in order to guarantee a safe and precise motion without generating high internal forces and slippage. Using the instantaneous centre of rotation (ICR) of the chassis to describe this motion is a well established method. But the ICR is a mathe...

Humans use direct physical interactions to move objects and guide people, and the same should be done with robots. However, most of today's mobile robots use non-backdrivable motors for locomotion, making them potentially dangerous in case of collision.

Robots fail to perform complex manipulation or locomotion tasks when using simple force or motion controllers applied to classic actuators. Stability and safety issues arise for reasons such as high output inertia and the non-collocation of sensing and actuating transducers. This paper presents a new actuation concept, integrating a DC motor and tw...

The most common ground locomotion method to make a mobile robot move is to use two-wheel drive with differential steering and a rear balancing caster. Controlling the two motors independently makes the robot non-holonomic in its motion. Such robots can work well indoor on flat surfaces and in environments adapted for wheelchairs. But the benefit of...

The design of interactive mobile robots is a multidisci- plinary endeavor that prots from putting robots with people and studying their effects and impacts. To do so, two main issues must be addressed: giving robots capabilities in order to interact in meaningful and ef- cient ways with people, and the ability to move in hu- man settings. This pape...

Navigating in rough terrain is a complex task that requires the robot to be considered as a holistic system. Algorithms, which don't consider the physical dimensions and capabilities of the mobile robot lead to inefficient motion and suffer from a lack of robustness. A physical model of the robot is necessary for trajectory control. In this paper,...
