Robotic Arm Edge
Build your own working robot arm! Voted “Best Pick of 2008” by Dr. Toy, the OWI Robotic Arm Edge kit has everything needed to make a functioning robot claw. Similar to the large ones used in automobile factories, but you control it to grab and pluck objects weighing up to 100 grams—like a stack of 20 nickels, or 25 packets of sugar. With a built-in searchlight the fun can be extended into challenging nighttime play. Four D batteries needed, not included.
