Linio is an autonomous robot based on Arduino that is able to drive and draw in an 8 by 8 matrix.
When it is driving this matrix form, Linio is able to draw or not draw according to the specifications set by its user, so eventually a 64-bit drawing appears.
In order to drive in straight lines and follow through from left to right and back from right to left again, 3D printed omniwheels are used.
