I believe this is the current location for the Lion Patch In the interests of finding it again when the LEGO group change their site again: Visit the LEGO Education page. Navigate to "Pre-school and School" -> Secondary -> 11+ LEGO MINDSTORMS Education -> Downloads (or similar) I then filtered the list to just the Download Type of "Software Update / ...

Lego's education catalog implies that the WeDo software is required for the hub to work. It states: The two-port hub controls motors and sensors, transmits power and data to and from the computer, and is automatically detected by the WeDo™ Software when connected to the computer. I found some info regarding WeDo software, the manual has this to ...

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 just created a Node.js library that supports reading and writing to the Lego WeDo kit: https://www.npmjs.com/package/wedo-support Install > npm install --save wedo-support Use const WeDo = require('wedo-support'); const wd = new WeDo.WeDo(); // Activating the first motor full forward: wd.motorA = 100; // Activating the second motor half ...

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: cycthon-hidapi, which itself depends on hidapi; homebrew can install that for you. cython likewise You'll likely ...

You can use WeDo with MIT Scratch 1.4 according to http://info.scratch.mit.edu/WeDo, and Scratch runs on Linux- and this thread https://lists.launchpad.net/scratch/msg00269.html indicates that the Linux Scratch does work with WeDo.

One motor and a caster wheel will give you two degrees of movement but will not be steerable. If you can build a differential, then drive two wheels with the motor. If you have limited gears, then drive one wheel, have an idler wheel and a caster or simple skid arrangement. You can get more interesting behaviour by having a bumpbot, that simple reverses ...

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 ...

I've just discover that the WEDO USB Hub just send to the motors 5V instead of 9V, so that's stopping me for doing a lot of stuff. Does anybody know how to add a separate source power and only send and read data from the USB Hub?
