Building Basic Prototype by Lego about qi-table

Built Lego structure which can hold the motors. Lego motor axel is short, so using gears to turn the wheel axel. Need to modify the structure some more to make sure it fits the Arduino. Possible issue with how the Arduino, and the other boards of similar size, will sit on the structure (as it's not a lego piece).

Used previous design for reference, using similar shape and working elements. New improved design includes a more rigid base, can handle more force at points -which were weak points on the previous design. And an added width element, useful for space which can be utilized by components and boards.
Due to the nature of the wires connecting between boards, I felt it necessary to add an extra shelf under the bot, where a board can sit.

During the testing whether the Lego prototype can turn, the friction produced by the front wheels, made it impossible for it do so. At this time, the wheels were removed and now it is able to move in all directions. This design (without the front two wheels) could be presentable during demo 1, but depending on availability, it might be a nice touch to solve the issue by putting a different type of wheel (one or two wheels) in the front to reduce the friction, hence allowing turning movement. If this is not possible the hardware team needs to convene and talk about next steps and the possibility of more powerful motors.

This was done for demo 1 with overwhelming success.
