Think of this as an analog robot. Wood and string combine to make a precision-grabbing device. The builder controls the bot with levers and string making a very satisfying and ingenious kit. Fun, hands-on learning at its best. Building models decreases stress and increases focus, organization, and spatial, and fine motor skills. All of our Curious Engineer kits are great Christmas and Hanukkah gifts. Bring all ages together for a fun engineering project. 14x13x2" box.
