A smarthub is an intelligent control unit to which can be connected executive devices - the motor and sensors and the smarthub itself, in turn, connects to a laptop / computer / tablet to receive control commands. In short, a smart hub is the “heart” of any robot.

The most successful innovation regarding the smart hub is the use of Bluetooth technology Low Energy (Bluetooth 4.0) instead of the usual USB-solution with a cable that connected the model to the laptop. Using Bluetooth makes the assembled robots autonomous and mobile. The reverse side of this is an increase in the size of the smart hub to 8x4 modules (length x width), and the a height is a 3 classic bricks. This is caused by the fact that “on board” it is necessary to fit the power source for the unit. Also, brick beams of 1x4 modules were placed on each side of the smart hub for using smarthub as a base element of model.

It is also worth noting that Bluetooth technology creates the problem of simultaneous connection of all smart hubs to the corresponding laptops / computers. It is possible to change the name of each Smart Hub in the WeDo Toolbox. The best solution is to assign an individual name for each smart hub, both in software and physically, using stickers or a permanent marker.
