Sonic Constructs

Sonic Constructs is a sound installation that uses Lego Mindstorms robots as musical instruments. Visitors participate by constructing their own Lego structures which in turn become actual sound making objects.


The movements of two robotic devices produce sound: direction, speed, acceleration, position, scratching and collision become parameters of an environment for kinetic and acoustic participation.

When a collision between the bots occurs (something usually regarded as a failure to detect and avoid obstacles), the construction collapses, creating an environment of fragments. This environment becomes the space for kinetic and acoustic participation. A resonant metal plate acts as a surface on which the constructs operate.
