An apparatus for mowing grass. The apparatus has a plurality of cutting devices for mowing the grass. The apparatus has a plurality of carrying arms which are arranged offset with respect to one another with regard to the transverse axis of the apparatus, and are supported such that they can be pivoted up and down in each case individually, and carry in each case one of the plurality of cutting devices. The apparatus has a plurality of supporting elements which support in each case one of the plurality of carrying arms on an underlying surface, and are arranged in front of the respective cutting device with regard to a forward moving direction of the apparatus. The apparatus can have the advantage that the leading supporting elements do not push any cuttings in front of them, and a risk of the apparatus being jacked up is decreased.

Apparatus including an autonomous robot apparatus for mowing grass

The invention relates to a trailer () for a bicycle (), having a braking device acting on wheel(s) () of the trailer (); a sensor device () which supplies a measured variable, which is a measure of an acceleration force acting on the trailer () via a tow bar (); a controller () for controlling the braking device and that is configured to act on the braking device, depending on the measured variable determined by the sensor device (), such that an inertial force of the trailer () generated in the pulling mode or during braking of the bicycle () is compensated for or is at least reduced; and a decoupling device () which is configured for the partial mechanical decoupling of a movement of the bicycle trailer () with respect to the bicycle () in the longitudinal direction of the bicycle trailer (L).
