● There are 10 models with a reptilian appearance. ● The newly designed claw with rolling and climbing functions make the models more realistic. ● The 28X motor with switch has better torque and faster speed, and can move clockwise and counterclockwise. It is easy and quick to assemble. ● Requires 2 AA/LR06 batteries – not included.
Description
Construct ten out-of-this-world machines and learn about the physics of levers and linkages. A battery-powered motor box powers the models. ●Make a creepy slithering alien snake-bot model with rotating arms and articulating tail. ●Build an alien insectoid-bot that crawls on six legs. ●Create an alien raptor model with wings that move up and down. ●Assemble a cool grabber claw with a scissors mechanism. ●Make a bipedal alien robot model that walks on two legs. In addition, build models of a pumpjack, swinging device, hopping alien frog-bot, roving dino-bot with reciprocating arm, and rolling alien dragon-bot. A 48-page manual guides your model building and experiments with step-by-step illustrated instructions.
