Ladybird a cute Lego robot . Iím a EV3 robot and I behave like a real ladybug. I can see, feel, walk and more. And I love to play! Watch the video and enjoy. . Video LadybirdThe seven-spot ladybird is the most common ladybird in Europe. She's also known as ladybug or Coccinella septempunctata. This Lego sculpture is 30 times larger than the real insect. Robot designThe ladybird robot is brought alive by Mindstorms EV3 technology. She can walk fully autonomous. Her eyes and antenna help her to find her way, just like a real Ladybird! The ladybird robot can respond to human & other robots by means of her infrared sensor and a beacon. See for example the video above. The beacon is also used for manual control of the robot. The robot ladybird is driven by wheels, although it looks if she walks with her moving legs. The left photo shows the walking mechanism. A crankshaft is connected to the wheel and motor, which drives the legs. The red wing covers can open automatically. Each cover rotates along two axes which are connected by a bevel gear. By this mechanism a realistic cover movement is achieved. The covers are actuated by a Power Functions M-motor. In order to control a Power Functions motor with an EV3 brick the following My block can be downloaded: Download EV3 with Power Functions. The robot ladybird opens her covers frequently to show her EV3 brick inside. Photos of real ladybirds were used to design the robot. Like the photo at the left: "7-spot ladybird (Coccinella septempunctata)" by Charlesjsharp, own work licensed under CC BY-SA 3.0 via Wikimedia Commons. Note the big white fake eyes aside of real eyes which are meant to scare enemies. Ladybirds look adorable but they are also vicious hunters see "Ladybug a mean aphid hunter". Enjoy ladybird robotics!
