Figure 1. ShapeBots exemplifies a new type of shape-changing interface that consists of a swarm of self-transformable robots. A) Two ShapeBot elements. B) A miniature reel-based linear actuator for self-transformation. By leveraging individual and collective transformation, ShapeBots can provide C) interactive physical display (e.g., rendering a rectangle), D) object actuation (e.g., cleaning up a desk), E) distributed shape display (e.g., rendering a dynamic surface), and F) embedded data physicalization (e.g., showing populations of states on a US map).
ABSTRACTWe introduce shape-changing swarm robots. A swarm of selftransformable robots can both individually and collectively change their configuration to display information, actuate objects, act as tangible controllers, visualize data, and provide physical affordances. ShapeBots is a concept prototype of shape-changing swarm robots. Each robot can change its shape by leveraging small linear actuators that are thin (2.5 cm) and highly extendable (up to 20cm) in both horizontal and vertical directions. The modular design of each actuator enables various shapes and geometries of self-transformation. We illustrate potential application scenarios and discuss how this type of interface opens up possibilities for the future of ubiquitous and distributed shape-changing interfaces.interfaces [5,38]-will follow the same path as technology advances. Although current interfaces are often large, heavy, and immobile, these interfaces will surely be replaced with hundreds of distributed interfaces, in the same way that desktop computers were replaced by hundreds of distributed mobile computers. If shape-changing interfaces will become truly ubiquitous, how can these interfaces be distributed and embedded into our everyday environment? This paper introduces shape-changing swarm robots for distributed shape-changing interfaces. Shape-changing swarm robots can both collectively and individually change their shape, so that they can collectively present information, act as controllers, actuate objects, represent data, and provide dynamic physical affordances.
