LEGO Wedo 2.0 Koala

Key Takeaways

well let the Koala like a cute little bear it actually isn't a bear at all today let's build a koala using Lego we do two [Music] the word koala comes from the durog word gula and although some people used to call them koala bears twelves are actually marsupials just like female kangaroos female koalas have pouches where their newborns finished developing koalas spend their lives living in trees and there have some really cool adaptations for this kind of lifestyle for example they have four thumbs in total two on each hand so that they can grab onto tree branches with really strong grip and the eucalyptus trees where koalas live in don't just provide shelter they also provide food koalas eat the eucalyptus leaves that are actually toxic to most animals they can do this because they have the ability to break down toxins inside their liver isn't that cool a koala lives in the home full of food that's poisonous to everyone else except for the Koala and despite having really powerful claws and a habit of eating poison for lunch a koala is surprisingly peaceful they spend up to 20 hours a day sleeping in their trees and this is because of the very low energy content of the food that they eat this is in stark contrast to their close cousins the drop bear which is a ferocious predator that feeds on humans all right let's go build our lego koala I want to build the model koala climbing up and down a tree so the first thing I do is build the eucalyptus tree where our koala will be climbing we will build a winch that will help pull our Koala up and down the tree and add a motion sensor to detect when the koala has reached the top this will allow us to stop and reverse the motor when the Koala is ready to climb down if we don't have the motion sensor and code in place then there is a chance that the winch can turn too much and jam the model finally we build the koala which I think is the cutest model we have created so far thanks for watching the video if you want building instructions and code for this model then please visit our patreon page in the link in the description until next time keep on creating
