Representing, learning, and controlling complex object interactions

Yilun Zhou, Benjamin Burchfiel, George Konidaris

Autonomous Robots > 2018 > 42 > 7 > 1355-1367

We present a framework for representing scenarios with complex object interactions, where a robot cannot directly interact with the object it wishes to control and must instead influence it via intermediate objects. For instance, a robot learning to drive a car can only change the car’s pose indirectly via the steering wheel, and must represent and reason about the relationship between its own grippers...

Herielton Luiz Bettini, Luís Gonzaga Trabasso

Journal of the Brazilian Society of Mechanical Sciences and Engineering > 2018 > 40 > 5 > 1-14

This paper presents the development of design to center of gravity (DT_CG) method, a new member of the DFX (design-for-excellence) design methodology. DT_CG constantly updates the position of the center of gravity of a product under development and inputs it as a requirement into the conceptual phase of the product development process. The CG requirement is yet another requirement to be considered...

Julio Cesar Frantz, Leonardo Mejia Rincon, Henrique Simas, Daniel Martins

Journal of the Brazilian Society of Mechanical Sciences and Engineering > 2018 > 40 > 4 > 1-9

Recently, industrial robots are being more and more widely used in a variety of machining applications, such as drilling, milling and grinding because of their flexibility in performing tasks in a relatively small space, and furthermore, at a lower cost. In many cases, the wrench capability of industrial robots is lower than the required, causing in some tasks the saturation of the actuators. The...

Isiah Zaplana, Luis Basanez

Mechanism and Machine Theory > 2018 > 121 > C > 829-843

This work addresses the inverse kinematic problem for redundant serial manipulators. Its importance relies on its effect in the programming and control of redundant robots. Besides, no general closed-form techniques have been developed so far. In this paper, redundant manipulators are reduced to non-redundant ones by selecting a set of joints, denoted redundant joints, and parametrizing its joint...
