In order to fix the front wheel structure, we pass the grey axis through the hole of the green beam, but in this way, the front wheel could not steer. Therefore, it will rotate around the black axis and cannot fix the shape of the front wheel structure. We simulate the model in the book to build the front wheel, but unfortunately, the green beam has only pin holes. Out first model is very simple, as shown below. Furthermore, it is the first time Ray tries to build tricycle. It is a simple tricycle model and it is even not connected to smart hub or motors, but we are interested in how the model could steer simply through mechanical design. Recently, Ray is attracted by his book and this time, he finds another model he is interested. In previous post, I introduced how to create a crane model by referring to the inspiration idea from the book of Yoshihito Isogawa.

Links to download the WeDo software can be found on LEGO Education Downloads.The LEGO Technic Idea Book – Wheeled Wonders. Although it is possible to untether the WeDo by powering the motor directly, it will not follow a program.

Creations need to remain tethered to the computer for power and to follow a program. The original LEGO WeDo Core Set (9580) has 158 pieces, including two sensors (tilt and motion), a motor, and a USB hub. WeDo 1.0 (9580) Original LEGO WeDo Core Set WeDo (1.0 and 2.0) can also be programmed using Scratch. Additional curriculum materials are also available from LEGO Education. Curriculum support that is targeted to science and computing is available from within software. Links to download the WeDo 2.0 software can be found on LEGO Education Downloads. The SmartHub is powered by either two AA batteries or a rechargeable battery pack (purchased separately). WeDo 2.0 features a programmable SmartHub that connects to a computer or tablet via Bluetooth Low Energy, meaning that there is no longer a need to physically tether creations to a computer (as was required with the original WeDo kit). The WeDo 2.0 Software is available for desktops and tablets and is free to download. The LEGO Education WeDo 2.0 Core Set (45300) contains 280 pieces, including a motor, and tilt sensor, and motion sensor. WeDo 2.0 was released at the beginning of 2016. The original WeDo set was released in 2009. LEGO WeDo is a robotics kit designed for younger students.
