  • Patent number: 8025551
    Abstract: A toy vehicle has first, second and third wheels for movement over a surface. Each of the first, second and third wheels has a respective first, second and third axis of rotation that lies between the remaining two other axes of rotation such that the three axes of rotation are mutually adjoining. Each of the three axes of rotation crosses over the other two axes of rotation such that an angle is formed between each adjoining crossing pair of the axes of rotation where each angle is other than a multiple of 90 degrees. Each wheel is individually powered so that the toy vehicle can translate in any horizontal direction regardless of its facing direction. Two of the wheels can be realigned so their axes of rotation are collinear for conventional movement.
