Human-Robot Collaborative Carrying of Objects with Unknown Deformation Characteristics

Robotic systems enable to make improvements to productiveness and quality in the industry. For instance, robots can collaborate with individuals in the transportation of objects.

Human-robot collaboration is possible in various tasks, not just industrial.

This endeavor poses numerous worries. Firstly, the robot must share the load with a human properly. Also, rotations and translations have to be managed independently. Additionally, co-transportation of deformable objects is problematic. A latest paper on arXiv.org aims to deal with these troubles.

The scientists propose an adaptive framework that merges haptic and human motion facts. That way, a mobile manipulator can co-transportation objects with unknown deformability for the duration of collaboration with a human. Also, a novel algorithm is developed to empower human companions to converse their intention of rotating an object by applying the torso and hand movements.

Experiments confirmed the usefulness of the introduced framework versus the admittance controller.

In this function, we introduce an adaptive management framework for human-robot collaborative transportation of objects with mysterious deformation conduct. The proposed framework requires as enter the haptic data transmitted by way of the object, and the kinematic information of the human system obtained from a movement seize technique to create reactive complete-system motions on a cell collaborative robotic. Also, the intended framework provides an intuitive way to rotate the item by processing the human torso and hand movements. In buy to validate our framework experimentally, we compared its efficiency with an admittance controller in the course of a co-transportation job of a partly deformable item. We in addition exhibit the prospective of the framework when co-transporting rigid (aluminum rod) and deformable (rope) objects. A mobile manipulator which consists of an Omni-directional mobile base, a collaborative robotic arm, and a robotic hand is made use of as the robotic partner in the experiments. Quantitative and qualitative success of a 12-subjects experiment present that the proposed framework can efficiently deal with objects of mysterious deformability and gives intuitive guidance to human partners.
