This can be done without a caster wheel as well:
Start out with a three wheeled vehicle, with two wheels in the front and one smaller wheel with less traction than the front wheels in the back. All wheels need to be fixed.
One of the front wheels is attached to the motor. This might need to have some gearing to get an appropriate speed.
The other front ...
I've tried attaching one of the Powered up motors from the batmobile set (76112) This motor looks identical to me as the WeDo motor (although brickset and bricklink don't list them as identical at the time of this writing)
I could not get it to work, all profiles of the fixed build models complain that the external motor is not attached. The free build ...
M Motor (Powered Up/WeDo 2.0)
The M motor has a 2.2kΩ resistor between pins 5 and 6. Pin 6 is connected directly to pin 3.
I don't own any lights yet, but according to this post, they also use a 2.2kΩ resistor, but in this case it is between pins 5 and 3. This pulls ID 1 to ground. Here's the full circuit diagram:
The measured ...
In WeDo 2.0 app "LEGO® Education WeDo 2.0" there is a complete project 12. Steer that is exactly about that
When it drives forward it goes in straight line, when it drives backward it then turns to one side.
There is full build instruction in the app.
I've also added distance sensor and made it fully autonomous - whenever it sees obstacle it goes back, ...
I designed some WeDo 2.0 models that can drive and steer using just one motor.
This one uses a system of gears to alternately drive the left or right wheel of a differential drive robot, depending on the turning direction of the motor.
You can find the complete building and programming instructions here:
According to the WeDo 2.0 FAQ
Is this a new plug system?
Yes, this is the new LEGO Power Functions plug that has been optimized also to meet potential future needs.
What does that mean for the existing plug systems on other Power Function and MINDSTORMS products? Will they also be changed?
Yes, eventually we will convert to the new plug system after a ...
This is not possible currently using any of the hardware and software provided officially by TLG. However, there are several solutions that might work for you if you have a spare Arduino or Raspberry Pi around and are willing to do a little programming.
If you aren't aware, all of the Powered Up elements communicate via a Bluetooth protocol that TLG provides ...
Based on the answer to this question and some experiments with other hubs and other motors today (Boost hub + Boost motor + small PoweredUp hub), it seems that the WeDo motors really lack any ability beyond "Run with power X". Given that the WeDo motor is the same model that is built into the Bat Mobile, I would expect that the PoweredUp app would ...

22 Amazing creations by Lego Wedo 2.0
I just created a Node.js library that supports reading and writing to the Lego WeDo kit: https://www.npmjs.com/package/wedo-support
> npm install --save wedo-support
const WeDo = require('wedo-support');
const wd = new WeDo.WeDo();
// Activating the first motor full forward:
wd.motorA = 100;
// Activating the second motor half speed/...
It is possible to drive the WeDo from Python on a Mac, without a kext. I've only tested motors since I don't (yet) have the other sensors. You need to access the USB HID device directly. There are a couple of prerequisites to install:
cython-hidapi, which itself depends on
hidapi; homebrew can install that for you.
You'll likely want ...
I've seen a few videos about Lego Wedo 2.0, and from what I can tell, it doesn't have it. One video shows a few of the models and some of the user's programs, but he doesn't mention even a virtual remote control and if it existed he would've because it's an obvious key feature for robotics. This was made without the official app and I bet ...
It depends on which app you want to use. My impression is that the Boost app can work with one Boost hub, one Boost motor and one Boost color/distance sensor.
If you use the PoweredUp app, you can use WeDo sensors and WeDo motors as well. But you always have to set the ports explicitely and remember that the external ports on the Boost hub are ports C and D. ...
Here's what I found researching your issue:
It seems that the issue with Mac OS X's kernel claiming HID USB devices before libusb does is a known issue since OSX 10.5 (see here).
Libusb has no functionality to alter this behavior, so it would be up to the WeDoMore developers to use an alternative way to utilize USB on the Mac if they want to build in this ...
