TerRoamer - A mobility platform suitable for obstacles

The idea

...is the provision of an easy-to-use, obstacle-compatible mobility aid, ideally with the addition of a certain "fun factor" and the characteristic of additionally demanding the existing natural mobility by "being active" and thus maintaining or even promoting it, in order to compensate for the mobility deficit that occurs with age. The use of this new form of mobility should also be attractive in an earlier phase of life, so that people can become familiar with it when they need it.

The solution

Used in mobile robotics for decades, wheel-legs, a combination of rolling and walking locomotion, provide a robust drive in an unstructured environment with obstacles of unknown geometry and composition. However, the height offset of the axle and the associated vibrations previously excluded its use as a drive in the field of passenger transport. In order to be able to use the advantages of the simply constructed wheel-legs for passenger transport, the height offset therefore has to be compensated. For this purpose, a restrained coupled mechanical solution was found and implemented, which consists of a slider-crank mechanism and a superimposed gear train . It requires only one drive for both height compensation and propulsion. In combination with an elastic upper mounting of the compensation unit, residual and higher-frequency vibrations are to be damped.
