This project provides new ways to work with Topobo motion sequences. The Backpacks are a series of physical components with a knob that can be attached to a Topobo Active. The Backpacks will modify the way your recorded motion plays back. For instance, by turning the knob on the Bigger/Smaller (Amplitude) Backpack, you can make the motion larger or smaller. Other Backpacks include "Time Delay," "Faster-Slower," and "Position Offset." The Position Offset Backpack has light sensors instead of a knob, allowing users to build creatures that can walk towards or away from light. The Backpacks introduce ideas about symbolic representation and feedback to Topobo.
