Meta.4 from Elenco introduces Robotics to younger children with larger, easier to handle parts. Build and rebuild 4 different models, one at a time. Your Meta.4 is powered by clean, green, sunlight so no batteries are ever needed. Builds can be easily dissembled and reassembled to make any one of the 4 models:
Build the T-Rex that walks on 2 legs with jaws that try to eat everything in their path
Build the Rhino Beetle with 6 legs and a gaping jaw
Build the Drill Vehicle with a rotating drill bit
Build the Robot with visible gears that shuffle it forward
