Modular Robotics makes robot construction kits. By combining sensor, logic and actuator blocks, young kids can create simple reconfigurable robots that exhibit surprisingly complex behavior. roBlocks are self-describing, so they can provide helpful feedback to the user, and automatically adjust their functionality based on how they've been assembled. The robotic blocks are 40mm plastic cubes with magnetic connectors, just pick them up and start building! Using just the blocks, you can create smart robots that sense, plan, and act.
