<p>This invention relates to an arragnement for carrying out unlimited movement patterns in a horizontal plane comprising a chassis carried by at least three wheel means, at least one wheel means functioning as a driving and controlling wheel, and the arrangement comprising a computer-based, electronic controlling system which can be programmed for intended purpose, and which is adapted for use in vehicles. According to the invention the arrangement is characterized by the following features: the driving and controlling wheel (1, 3) is arranged partly to be able to rotate about a first axis (5), forming an angle which is greater than 0° but less than 90° with the horizontal line, partly to be able to rotate about a second, essentially vertical axis (6); each driving and controlling wheel (1, 3) is obliquely positioned, has essentially sub-spherical design and is driven by a motor of its own and is separately controlled; the driving and controlling wheel (1, 3) is provided with one or more pulse transducers (12a, b) which are arranged for giving off signals, reflecting one or more parameters, for instance the angle position and speed of the mentioned wheel.</p> |
