![]() See the Wikipedia article on casters, but there is a strong relationship between wheel diameter and how high the caster should be. You can get more interesting behaviour by having a bumpbot, that simply reverses the motor when it detects an obstacle. If you have limited gears, then drive one wheel, have an idler wheel and a caster or simple skid arrangement. If you can build a differential, then drive two wheels with the motor. One motor and a caster wheel will give you two degrees of movement but will not be steerable. Here a good WeDo 2.0 model with steering: UPDATE 2: Got a nice suggestion at Eurobricks forum: I wonder if experienced LEGO builders can propose a better vehicle out of WeDo 2.0 parts than mine:Īnd I feel that my Scratch program can be improved too, since it is not very responsive to user input (when touching the 4 green arrows): There is too much friction - on the axles of all 3 wheels and on the rubber band. I have followed Aaganrmu's suggestion (thank you) and have tried to build a simple vehicle using ratchet instead of caster wheel: The caster wheel would roll straight, when the vehicle drives forwards.īut when driving backwards, it would snap to a certain angle.įound a picture for such a caster wheel in the LEGO Technic Idea Book by Mr. I am thinking of having 2 wheels with wide tires in front the vehicle, connected to the motor.Īnd having a single caster wheel with narrow tire at the back of the vehicle, not connected to the motor. The final mission is to make kids sensitive to STEM world.In WeDo 2.0 set there is only 1 motor, which can be remotely switched on and off by using the iPad app (by writing a Scratch program).Īlso motor rotating direction can be toggled remotely.Īs an inexperienced LEGO builder I wonder if it is possible to build a remote-controlled vehicle out of 280 WeDo 2.0 pieces, which would be steered by changing the motor rotation direction. By using their specific application, children can bring their creations to life with icon-based drag-and-drop coding interface that interprets the computer language. However, the emphasis of these two ranges is on the introduction of the basics of programming and robotics in a fun way through constructions of Lego toys. The same for the instruction guide, only a digital version is provided in this kit and available on the same application. These Lego Boost creations are totally controlled and coming to life from a tablet application on IOS and Android. On the other hand, the basic concept remains the same. Lego Boost bricks are considered as the more advanced version of those in LegoWe Do2.0, since Lego Boost is Lego's new product in 2017. 1 Color & Distance Sensor allowing to detect distance, motion and color and can function as a light.1 interactive Motor is an encoded motor.1 Move Hub allowing BLE connection, includes two encoded motors, activation button, internal tilt sensors and a light.These 3 Boost pieces are at the heart of this range that introduces to the programming: This kit includes 840 Lego bricks as well as 3 Boost blocks. With a single Lego Boost kit, children can create 5 basic models. It is a range intended for the general public. It combines construction and robotics, the aim is being to introduce children from the age of 7 years old to the basic notions of computer programming and robotics. While Lego Boost is the latest range of Lego released in summer 2017. Inside the kit, we will find the pedagogical resources, so that teachers can help their students to discover the robotic world. These 4 bricks are controlled from a mobile application via BLE or on PC and Mac.Ī Lego WeDo2.0 kit is designed for 16 default projects and for 2 students. ![]() This kit mixes 276 Lego classic bricks and 4 electronic bricks to give life to the Lego creations: Kids in elementary (from 7 years old) can practice algorithmic logic and the ability to solve a problem by assembling toys in class. Lego WeDo 2.0 offers Lego educational solutions. Lego WeDo 2.0 is part of the Lego Education series, launched in 2016, that is to say, it is a kit specifically designed for classroom learning.
