We describe work in progress on roBlocks, a computational construction kit that encourages users to experiment and play with a collection of sensor, logic and actuator blocks, exposing them to a variety of advanced concepts including kinematics, feedback and distributed control. Its interface presents novice users with a simple, tangible set of robotic(More)
Distributed computational toys are physical artifacts that function based on the coordination of more than one computing device. Often, these toys take the form of a microcontroller network embedded in a children's construction kit. We present a survey of distributed computational toys. Although most of the toys we surveyed were built in the last five years(More)
In this paper we describe an optimal reconfiguration planning algorithm that morphs a grounded truss structure of known geometry into a new geometry. The plan consists of a sequence of paths to move truss elements to their new locations that generate the new truss geometry. The trusses are grounded and remain connected at all time. Intuitively, the(More)
We present progress with roBlocks, a reconfigurable modular robotic system for education. Children snap together small, magnetic, heterogeneous modules to create larger, more complex robotic constructions. The design of the system is described and the algorithms that handle data transfer and manipulation are explained. Users tend to begin exploring the(More)
Graphs are a versatile representation of many systems in computer science, the social sciences, and mathematics, but graph theory is not taught in schools. We present our work on Graphmaster, a computationally enhanced construction kit that enables children to build graphs of their own and investigate their properties by experimenting with algorithms that(More)
