What about Lego Boost
I've used this free helper app S2Bot to connect Lego Boost to Scratch and it's fun. I posted a video on YouTube showing some photos, film clips and Scratch code for the Lego Boost robot called Vernie:
The move hub of Lego Boost has two motors inside and you can code how many steps (turns) the motor has to make or the position the motor axis has to go to, usings Scratch. There is a thirth motor with the same features that can be connected to the hub with a small cable. Being able to programm steps is cool, but there seems to be no way to just turn the motor on and off, which made steering Vernie using the Arrow keys difficult.
Furthermore, there is a separate colour sensor, which can return numbers from 1 to 10 to Scratch, depending on which colour it “sees”.
The move hub also has a tilt sensor inside and this one returns more values than the tilt sensors of Lego WeDo. Therefore, you can also use it as a controler for a Scratch game, like you can see in this video (not by me):
Please be aware a 3.BLED112 bluetooth dongle (not required for Chromebooks) is needed to use the S2Bot. No other type of dongle is compatible.
