Visuo-tactile Mixed Reality for Offline Cobot Programming

Multimodal Mixed Reality Impact on a Hand Guiding Task with a Holographic Cobot

“…The research methodology employed included the measurement and assessment of a substantially larges set of variables that were used in the prior pilot study [7]. During the study, data were collected by two means: (i) validated and ad hoc questionnaires filled in by each participant at different points during the session, and (ii) observed (i.e., objective) data about the interaction logged by the computer system managing the session.…”

“…Similarly, the SEQ questionnaire was also extended with an additional category, "satisfaction with the result obtained" on the same scale format. The preliminary pilot study [7] did not make use of any of these methodologies, but it did include a brief ad hoc questionnaire. For the sake of comparison of results between the preliminary pilot study and this full study, we did also include the same ad hoc questionnaire in this case.…”

“…Finally, we administered the same ad hoc questionnaire as in the preliminary study [7]. This questionnaire consisted of four statements that the users had to answer to on a Likert 7-point scale, indicating whether they agreed with them (3) or not (−3): The distribution of the answers is shown in Figure 14.…”

“…In preliminary earlier work [7], we prototyped this concept by creating an application with which the user could perform a pick-and-place task of the wrist of a holographic robot. This task represents a part of the hand guidance programming process.…”

Development of a Cobot Lab to Support Next-Generation Applied Engineering Technology

“…The robotics software used with IRBs and CRBs offers a chance to bring industry 4.0 concepts such as digital twins and simulation into the curriculum [6]. While the current curriculum includes digital twins of the IRB and CRB stations, where students create and test applications offline before deploying them to the physical robot, recent technological advances have allowed for incorporating extended and mixed realities with offline programming tools to aid in planning, programming, and visualizing operations [7]. The next steps of the lab development will be to revisit the curricular goals and opportunities of the program to determine if this focus can be added to the existing course or if there is sufficient need to warrant future courses and capstone experiences.…”
