On the left of this image is a description of the Oxboard, as follows:

The Oxboard is a personal transporter. It is a board with two wheels, one each side. Oxboard has two built-in motors fed by a battery pack. You can go forwards or backwards with the Oxboard but also take left or right-hand bends. The compact design also ensures that you can use the Oxboard both inside and outside.

The Oxboard is a clever device that reacts to how your weight is distributed. The trick is in particular to relax when standing on the Oxboard; the Oxboard will then ensure the best balance. The Oxboard wil react directly if you distribute your weight ‘unevenly’; lean forward and you will move forwards, lean to the left and the Oxboard veers to the left. etc.

On the right is a photograph of the Oxboard with the following components labelled: crash bumpers; rubber mat with sensors below that sense how you are leaning on the Oxboard; battery indicators; motor, wheels and tyres; LED lights; on button; connector for charger.
