Outline and Objectives

Floating-base manipulators represent the short-term future core technology in factories and are aimed to achieve sophisticated, high-performance industrial processes allowing flexibility and reliability. These robots offer substantial benefits for many industrial applications due to enhanced dynamic and interaction skills. They are less specialized systems than fixed-based robots, providing several opportunities in terms of versatility and adaptability. However, this also implies that new issues not presented in traditional industrial robotics have to be faced. Some of the most relevant ones include a high level of complexity due to kinematic redundancy, working in unstructured environments, coexistence/cooperation with human workers, and a lack of systematic industrial design of human-robot interaction interfaces. Overall, numerous challenges regarding such wide-opened topics as whole-body control, underactuated systems, motion planning, physical robot interaction, or human-robot collaboration, among others, have to be determined.

In this respect, the correct definition of the opportunities involved in implementing these platforms is key to attracting the industrial sector's interest. Likewise, it is imperative to determine the challenges that must be faced to make floating base robots in real industrial applications a reality. This workshop will address the application of floating-base robots in manufacturing and logistics environments. In particular, the workshop will focus on setting up the challenges and opportunities on this topic according to the following questions:

  1. What are the main issues and challenges regarding the application of floating-base robots to manufacturing and logistics operations?
  2. How should these challenges be tackled?
  3. What benefits would the solution to these challenges bring to society and the manufacturing and logistics processes? 

Consequently, this workshop aims to provide a platform for top researchers from the robotics and industrial communities to share their work and inspire cross-discipline collaboration, motivating more integrated research approaches to apply floating-base robots in manufacturing and logistics.

Humanoids robotics in manufacturing and services [video]

Humanoid robots (humanoids) are gaining more maturity in terms of hardware and embedded software intelligence. Each year we witness substantial improvement of an existing series and the revelation of new platforms. So far, humanoids' developments have been confined to research, and there is still much to do in several specific aspects in order to engage into an innovation pathway toward full industrial products. The first revealed applications and business cases of humanoid robots are oriented toward entertainments and disaster operations. In previous years, we focused our efforts on applications of humanoids in manufacturing and domotic assistance for frail persons.

Collaborative robot programming for manufacturing [video]

In this talk, Dondheui explains how robot programming can enhance robot programming for manufacturing applications. The current trend of collaborative robot programming is changing from intuitive interfaces (i.e., touchpad) to direct teaching (i.e., Program by Demonstrations), improved by the use of Learning from Demonstration. The talk tackles the problems of robot learning by kinesthetic teaching, multiple tasks, conditional tasks, and continual learning, aiming to answer the question: "how does robot learning enhance robot programming?"

Who would dare to work side by side with a potentially exploding robot? Thoughts and insights about truly robust and safe floating-base robot controllers. [video]

To the best of the speaker’s knowledge, state of the art floating-base whole-body controllers (WBC) are either based on heuristics (lacking any stability guarantees), or they are highly dependent on correct contact assumptions. The latter, purely model-based and “cleaner” family of controllers tends to become unstable (the robot basically “explodes”) when contacts are lost (e.g. when the robot is lifted without knowing, stepping into a hole, slipping heavily, etc.). In his talk, Johannes will give a brief overview of the state of the art in floating-base robot WBC, specifically with regard to its “contact-robustness”, share some insights into his group’s recent developments and give a sneak preview (including key challenges) about his envisioned ever-robust WBC framework.

Posture-dependent robust stabilization of flexible-base manipulators [video]

The work shown in this presentation introduces an analytical illustration of the normalized coprime factor (NCF)    stab         ility margin, common in H∞ control, as applied to flexible- base manipulators. This metric can be used to describe the              stability of such robots for a particular posture without necessitating the design of an exact controller. This enables the use of simple task-space feedback control without explicitly modeling the flexibility of the robot’s base. Two proofs are included: th  e first being the definition of the NCF stability margin for the class of all rigid (double-integrator) systems, and the second presenting a special case wherein the rigid and flexible modes are simultaneously diagonalizable. Lastly numerical examples are  presented that illustrate the efficacy of using the NCF stability margin to determine stability of a flexible-base robotic system.

Active Supernumerary Bodies for Physical Robotic Assistance in Industrial Operations [video]

This talk describes a new collaborative robotic system that subsumes the advantages of mobile manipulators and supernumerary limbs. By exploiting the reconfiguration potential of collaborative mobile manipulators, this talk proposes a new collaborative robotic system that can be physically coupled to the human counterpart a supernumerary body. Through an admittance interface, the user can locally operate the supernumerary robotic body and send different commands to the controller when performing conjoined actions. Different interfaces, controllers, and applications are described. The proposed technology has a high potential for industrial tasks in terms of effort reduction, flexibility, and reconfigurability.

Floating Platforms and pHRI. End Effector Considerations [video]

This work proposes different solutions to improving the floating base platforms that have to interact with humans. The contributions are based on new end-effector designs for grasping and manipulating human limbs. In particular, methods for the improvement of the interaction safety, based on the estimation of positions of the human with respect to underactuated grippers from proprioceptive information, have been referenced. With the same purpose, a modified design of the gripper and a method is presented to estimate both grasping and interaction forces. Finally, design optimization is suggested based on reducing the number of arms in the floating base platforms by using in-hand manipulation techniques and presenting a pHRI hand with active surfaces.

Difficulties in Assembly Task for Floating-base Robots [video]

The use of floating-base can provide a large workspace for assembly tasks, especially for moving objects and manipulating large objects. However, there are inherently difficult problems in assembly tasks, such as uncertainties in modeling and sensing, and motion planning for the task. In this talk, I would like to introduce our recent project about assembling a chair with multiple manipulators, and share the difficulties in tasks assembling a chair. Then, the expected advantages and challenges are briefly discussed when the manipulators with floating-base are used for the assembly tasks.
