Maybe LEGO is targeting this educational set for the primary students, there are very limited programming blocks as choices.

It can detect the moving palm in front of it, but will miss some obstacles sometimes. and till now, I could not invoke its shaking status, yet.įor motion sensor, it can detect the movement of objects within 10 centimeters. Minor tilting angles like change of 5 degrees, 10 degrees can not be detected. For example, the tilt sensor can detect tilting status of up, down, left, right or shaking, but you have to tilt it to a bigger angle to recognize the tilting status. We test both motion sensor and tilt sensor and realize that they are not so precise. Think about LEGO Mindstorms EV3, its core set contains two motors which can turn at different speed to steer the model with curved or tank movement. If you want your model to have more functionality, two Smarthub and two motors are really necessary. Anyway, I feel that WeDo 2.0 could be better if the Smarthub contains at least three ports, instead of the existing two ports. Maybe one motor is not powerful enough to drive a heavier model, so you need to add a second motor. As Smarthub is big and a bit heavy compared to other LEGO blocks, your model should also become bigger to accommodate an extra Smarthub. Of course, this problem can be solved by adding another Smarthub to your model. That means, if you model needs to utilize motor to drive, you could only choose to connect one sensor – either motion sensor or tilt sensor, which limits the functionality of the model.

When the motor is connected to Smarthub, there is only one port left for the two sensors. The core set of WeDo 2.0 contains one motor and two sensors – one motion sensor and one tilt sensor. It makes the LEGO WeDo 2.0 courses a syntheses of STEM – the science, technology, engineering and mathematics. It emphasizes not only the mechanical models but also the related scientific technology and social topics. Combination of Science and Engineeringįor each tutorial project, the theme ranges from environmental protection, plants or animals, disaster monitoring to engineering analysis etc. I think that is also the advantages of LEGO group. In my personal view, I really like the overall design of mechanical models.

In terms of those mechanical structures, even secondary schoolers could benefit a lot on how to work on those gears, axis, rim, rack, worm gear to design exquisite mechanical structure. Meanwhile, based on those sample models, students can make freestyle designs to create other mechanical structures.Īlthough LEGO mentions that WeDo 2.0 is targeted to primary 3-5 students. For the 16 tutorial projects, all of those above simple mechanics have been covered and can be built step by step. The mechanical models of LEGO WeDo 2.0 cover some typical mechanical structures, such as gears, bevel gears, rack, worm gears, crankshaft, pulley, belt drive, etc. When our instructors are developing WeDo 2.0 courses, we evaluate both its strength and weaknesses and the following only represents our own opinion. Quoted from “LEGO Education WeDo 2.0 Introduction” document WeDo 2.0 supports a hands-on, “minds on” learning solution that gives students the confidence to ask questions and the tools to find the answers and to solve real-life problems. This is done through the use of motorized LEGO® models and simple programming. LEGO® Education WeDo 2.0 is developed to engage and motivate elementary students’ interest in learning science- and engineering-related subjects.
