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.
About this creation

Video



Ladybird

The 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 design

The 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.


More ladybird robot news will be released soon.

Enjoy ladybird robotics!

Quoting Bill Bourn I'm sure your model is 30 ladybugs long. Because it is a 3D model that makes it 27,000 times the size of a ladybug. Size goes up as the cube of the increase in linear dimension. Amazing work here. Thanks for sharing it.
27.000 times the size of an ordinary ladybug. That's what I would call a Giant Ladybug :) Thanks for your comment.

Quoting Sebeus I This is really awesome, The opening covers are a piece of brilliance, I'm impressed that you managed to achieve such a round thin shell shape while it still is sturdy enough to handle the movements, hoping to see it for real sometime, BM Antwerpen maybe?
Hi Sebeus, Thank you! The thin shell shape was indeed a big challenge, also because the weight needs to be low to prevent overloading of the joint. We certainly intend to show it at BeLUG. Brick Mania Limburg will be the first event. Tot ziens!

I love this ladybug. My favourite part is how the wings open just like the real insect! The shaping is really wonderful, and it is just a joy to watch it crawl around.

This is undoubtedly an extraordinary LEGO creation. I had no idea EV3 can control Power Functions. Great work :-)

Quoting David Roberts Wonderful fun from both the excellent shaping and the technology underneath. You might need to explain to American viewers about a ladybird being British English for what they call a ladybug!
Hi David, Thank you for your great feedback & suggestion! I just added Ladybug in the text. Regards,

It would be a little unsettling to see one of these things crawling toward you, haha! The MOC itself is great and the Power Functions...no words.
