Abstract

In a chassis (1) for a robot for traveling over smooth, curved or firm surfaces with two track guides that are mirror-symmetric to one another and firmly arranged in the chassis (1) in parallel with the traveling surface and self-contained in each case, along which controllable adhesive modules (14) circulate one behind the other in such a way that their adhesive feet (15), which can be lifted and lowered vis-a-vis the traveling surface, always point towards the traveling surface, the individual adhesive modules (14) have their own controllable lifting and traveling drives in each case.

Claims

1. Chassis for a robot for traveling over smooth, curved or firm surfaces with two track guides that are mirror-symmetric to one another and firmly arranged in the chassis in parallel with the traveling surface and self-contained in each case, along which controllable adhesive modules circulate one behind the other in such a way that adhesive feet of the adhesive modules, which are lifted and lowered to the traveling surface, always point towards the traveling surface,

characterized in that

the individual adhesive modules each have their own controllable lifting and traveling drives, wherein each adhesive module has a combined lifting and traveling drive that can be driven by the module'"'"'s own electric motor.

2. Chassis in accordance with claim 1,

characterized by

an automatically controllable changeover from lifting mode to traveling mode for each individual adhesive module.

3. Chassis according to claim 1,

characterized by

a continuously variable lifting and traveling mode for each individual adhesive module.

4. Chassis according to claim 1,

characterized in that

the track guides of a chassis are comprised of two straight guides in parallel with one another with connected circular-arc guides that lie in a conceptual full circle which includes the straight guides.

5. Chassis according to claim 1,

characterized in that

only the adhesive feet of the adhesive modules that are lowered on the straight guides and that run concordantly make straightaway travel (forward travel, reverse travel) of the chassis possible, whereas only the adhesive feet of the adhesive modules that are lowered on circular-arc guides and that run concordantly make a rotation (clockwise, counter-clockwise) of the chassis possible.

6. Chassis according to claim 1,

characterized in that

the track guides are comprised of guide rails in which accompanying rack rails are installed in which gears of the adhesive modules driven by traveling drives mesh.

7. Chassis according to claim 1,

characterized in that

the adhesive modules adhere to a traveling surface via suction force or electromagnetic force.

8. Chassis according to claim 1,

characterized in that

the chassis carries a remote-controlled traveling-surface cleaning device.

9. Chassis according to claim 1,

characterized in that

the chassis carries, solely or additionally, a remote-controlled inspection device or a remote-controlled manipulator.
