“…The long term goal of the Cellulo project is to show the utility of the platform as a practical educative tool (discussed in [30]) but other potential applications exist beyond education. As the robots are precisely localized and are capable of haptic output, a particularly appealing application is interfaces for the visually impaired (both learners and users), such as interactive geographical maps (e.g.…”

“…The Cellulo robot is designed with certain constraints that are closely related with its intended educational application focus (discussed in detail in [30]). Namely, our robots must be small enough to be graspable and contain a locomotion system that improves upon the commonly found differential drive (2DOF) in similar active tangible devices to enable instantaneous motion towards any direction when grasped, in order to shift towards a 3DOF haptic device; provide readiness of connectivity with pervasive smart devices (phones, tablets etc.…”

“…One powerful aspect of this proposed concept is that it provides physical interaction points (tangible and haptic) within the activity to the learners that are working separately or collaboratively through many robots. These points of interaction may be allocated to singular learners, possibly within groups (as in [29] where learners each have one "hot air balloon" to "feel the winds" on a geographical map to learn the wind formation through atmospheric pressure) or may be shared among the group (as in the chemistry concept presented in [30] where learners freely interact with "particle"s, feeling inter-atomic and inter-molecular forces in a "test chamber" to form and break molecules and play with pressure/temperature). The long term goal of the Cellulo project is to build, using these haptic-enabled tangible robots (among other elements) to create a versatile, ubiquitous, robust and low-cost tool for education that touches vast areas of curricula; [30] includes in-depth discussions about our project's goals and motivations.…”

The Cellulo robots are small tangible robots that are designed to represent virtual interactive point-like objects that reside on a plane within carefully designed learning activities. In the context of these activities, our robots not only display autonomous motion and act as tangible interfaces, but are also usable as haptic devices in order to exploit, for instance, kinesthetic learning. In this article, we present the design and analysis of the haptic interaction module of the Cellulo robots. We first detail our hardware and controller design that is low-cost and versatile. Then, we describe the task-based experimental procedure to evaluate the robot's haptic abilities. We show that our robot is usable in most of the tested tasks and extract perceptive and manipulative guidelines for the design of haptic elements to be integrated in future learning activities. We conclude with limitations of the system and future work.

“…Currently, BotMap relies on robots, an underlying screen, and a camera placed above the table, leading to a quite complex setup. With recent robots such as the latest Ozobots, 9 which can be controlled remotely using a mobile application, or Cellulos [48], which are hand-held robots that can be used on non-interactive surfaces, the underlying screen would be useless.…”

The development of novel shape-changing or actuated tabletop tangible interfaces opens new perspectives for the design of physical and dynamic maps, especially for visually impaired (VI) users. Such maps would allow non-visual haptic exploration with advanced functions, such as panning and zooming. In this study, we designed an actuated tangible tabletop interface, called BotMap, allowing the exploration of geographic data through non-visual panning and zooming. In BotMap, small robots represent landmarks and move to their correct position whenever the map is refreshed. Users can interact with the robots to retrieve the names of the landmarks they represent. We designed two interfaces, named Keyboard and Sliders, which enable users to pan and zoom. Two evaluations were conducted with, respectively, ten blindfolded and eight VI participants. Results show that both interfaces were usable, with a slight advantage for the Keyboard interface in terms of navigation performance and map comprehension, and that, even when many panning and zooming operations were required, VI participants were able to understand the maps. Most participants managed to accurately reconstruct maps after exploration. Finally, we observed three VI people using the system and performing a classical task consisting in finding the more appropriate itinerary for a journey.

“…Indeed, for a robotic tool to be used in school environments, they need to have their usefulness and ease of use proved in the teacher's practice. The Cellulo project (described in detail in [6]) addresses this challenge of showing teachers that robotic tools can be used in schools in various curricular activities.…”

One of the main issues with the acceptance of robotic tools in schools is the extracurricular aspect of the learning activities using these robots. In the Cellulo project, we developed a novel robotic platform that aims to provide a ubiquitous, versatile and practical tool for teachers with subjects varying among the different topics at their respective school curricula. In order to show the potential of Cellulo in the classroom as part of standard curricular activities, we designed a learning activity called Windfield that aims to teach the atmospheric formation mechanism of wind to early middle school children.
