Abstract

A robotic work tool system ( 200 ) comprising a robotic work tool ( 100 ), said robotic work tool ( 100 ) comprising a chassis ( 140 B) and a body ( 140 A) and at least one support pillar ( 310 ) arranged on one of the chassis ( 140 B) and the body ( 140 A) and a corresponding support surface ( 320 ) arranged on the other of the chassis ( 140 B) and the body ( 140 A), wherein the support pillar substantially bridges a distance between the chassis ( 140 B) and the body ( 140 A) thereby impairing any roll or tilt of the body ( 140 A) relative the chassis ( 140 B).

First claim

The invention claimed is:

1. A robotic work tool system comprising a robotic work tool, wherein said robotic work tool is a robotic lawnmower, and wherein said robotic work tool comprises:
a chassis:
a body; and
at least one support pillar arranged on one of the chassis or the body and a corresponding support surface arranged on the other of the chassis or the body,
wherein said at least one support pillar substantially bridges a distance between the chassis and the body thereby impairing any roll or tilt of the body relative to the chassis, and wherein said at least one support pillar is not attached to said support surface.

2. The robotic work tool system according to claim 1 , wherein said at least one support pillar is arranged at a side of a fixation point.

3. The robotic work tool system according to claim 1 , wherein said at least one support pillar is arranged at a corner of said robotic work tool.

4. The robotic work tool system according to claim 1 , wherein said at least one support pillar is arranged to extend substantially across said distance, but leave a gap between the at least one support pillar and the corresponding support surface.

5. The robotic work tool system according to claim 1 , wherein said at least one support pillar extends vertically from said one of the chassis and the body toward said other of the chassis and the body.

6. A robotic work tool system comprising a robotic work tool, the robotic work tool comprising:
a chassis;
a body; and
a support pillar arranged on one of the chassis or the body and a corresponding support surface arranged on the other of the chassis or the body,
wherein the support pillar substantially bridges a distance between the chassis and the body thereby impairing any roll or tilt of the body relative to the chassis, and
wherein the support pillar extends vertically from the one of the chassis or the body toward the other of the chassis or the body.

7. The robotic work tool system according to claim 6 , wherein the support pillar is not attached to the corresponding support surface.

8. The robotic work tool system according to claim 6 , wherein the robotic work tool is a robotic lawnmower.

9. The robotic work tool system according to claim 6 , wherein the support pillar is arranged at a side of a fixation point.

10. The robotic work tool system according to claim 6 , wherein the support pillar is arranged at a corner of the robotic work tool.

11. The robotic work tool system according to claim 6 , wherein the support pillar is arranged to extend substantially across the distance, but leave a gap between the support pillar and the corresponding support surface.

12. A robotic work tool system comprising a robotic work tool, the robotic work tool comprising:
a chassis;
a body; and
a support pillar arranged on one of the chassis or the body and a corresponding support surface arranged on the other of the chassis or the body,
wherein the support pillar substantially bridges a distance between the chassis and the body thereby impairing any roll or tilt of the body relative to the chassis, and
wherein a gap is defined between the support pillar and the corresponding support surface.

13. The robotic work tool system according to claim 12 , wherein the support pillar is arranged at a side of a fixation point.

14. The robotic work tool system according to claim 12 , wherein the support pillar is arranged at a corner of the robotic work tool.

15. The robotic work tool system according to claim 12 , wherein the support pillar is arranged to extend substantially across the distance.

16. The robotic work tool system according to claim 12 , wherein the robotic work tool is a robotic lawnmower.

17. The robotic work tool system according to claim 12 , wherein the support pillar extends vertically from the one of the chassis or the body toward the other of the chassis or the body.
