A larva is a baby bug, and where that juvenile insect wanders to before it becomes an adult (called imago) is an important part of the lifecycle of its species. The Hexbug Larva micro robot moves a lot like an organic larva, and where it goes depends on what its optical sensor detects. When it gets close to an obstacle, it reacts by wiggling around and heading the other way. This exploratory robot is 4” inches long; batteries are included. Comes in clear plastic orange, green, blue, red, and black versions. We pick your larva color based on availability.
