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 pump Jack, swinging device, hopping Alien frog-bot, roving dyno-bot with reciprocating arm, and rolling Alien dragon-bot.
