The important part is the modified plates on the bottom with the socket joints. Start by building up a head shape with blocks you have. That will let you fix the lower claw on sideways. To fix the lower claw to the upper, use a technic brick at the bottom of the main claw with a friction pin attached. Liam used a combination of angles and arches to get the shape he wanted.

If you’re working with the full Lego Wedo kit, you’ll probably find these a bit easier than Liam did.
Then, use the final pin to fix the beam and brick together, like in the image below.įor the pincers, you can get creative here. This will change as you create different dance moves. At this stage, don’t worry about which hole you use on the gear. Pin the end of the brick to the main 12-long brick, and the end of the beam to a hole in the 24-tooth gear on the same side.

Use an 8-long technic brick and a 7-hole technic beam for each leg, plus three non-friction pins. When you’re happy with the movement of the motor and gears, you can start building the legs, pincers and eyes. This helps you to check that all the gearing is spinning at it should. At this point, connect your smarthub to Scratch and run the motor. Thread the axle through the right hole in the technic brick, and secure it on the back. Check where the gears will need to be aligned so that they interlock with the 8-tooth. To do this, put a cap-ended axle through the centre of each gear. The 24-tooth gears need to be free-spinning in order to work properly. Then, add an 8-tooth gear to the end.Īt the back, a pulley wheel fixed to a short technic brick lifts the smarthub and helps the crab move side to side. Insert a small axle through the centre hole of the technic brick and into the motor. Attach a 4-long and a 12-long technic brick directly in front of the motor. With the smarthub light facing forwards, fix the motor on top towards the back of the hub.
The body of the crab is built on the Lego Wedo smarthub. The app is a very big download, just under 500MB, but once you’ve got it installed, it’s very easy to set up and get started. For us, a big benefit of having the project instructions within the app is that they’re all in one place, and they can’t get lost or damaged. The app contains instructions for heaps of Wedo projects, and an image-based coding platform that communicates with the smarthub via bluetooth. As you would expect, it’s compatible with all the standard Lego and Technic components.Īlongside the kit comes the Lego Wedo 2.0 app. The core kit comes with a smarthub, motor, tilt sensor and motion sensor, plus a range of gears, wheels, axles and bricks to create a wide range of projects. Lego Wedo 2.0 is Lego’s entry-level robotics & coding kit, designed for the education space.
