Abstract:
A tree shaking device for collecting fruits from trees, comprising a housing (2) containing an eccentric kinematic mechanism (3); a reciprocating rod (4) partially housed within said housing (2) and equipped at the free end with a hook (11); a front tubular handgrip (13) which partially embraces said rod (4) and a rear handgrip (15) on which the motor controls are mounted. The front handgrip (13) is freely slidable over a tubular protection (10) fastened to the housing, thus reducing the transmission of reaction forces to the user.
Abstract:
The present invention refers to fertilizing compositions comprising inorganic particles of a calcium phosphate compound substituted with micro and macro elements and surface functionalised with at least one organic compound containing at least one hydroxyl group and at least one micro or macro nutritional element and/or comprising a substituted and possibly surface functionalised calcium carbonate compound. Other aspects of the invention include a process for preparing fertilizing compositions and processes for preparing particles of calcium phosphate compound and calcium carbonate compound.
Abstract:
The present invention relates to a method for controlling a self-propelled robot device, such as a robot device for mowing grass, and a control system that carries out the aforementioned method. According to the invention, the self- propelled robot device (10) is driven by an inertial navigation system (24) for a set time period or distance and said device is periodically stopped for rectifying the position and advancing course thereof by means of a satellite detection system (26) : the periodic correction of the inertial navigation system using satellite detections thus prevents course errors from accumulating. The correction based on the satellite detection system can be possibly optimized through a further selection of the obtained values according to a statistical basis. Preferably, the control method according to the invention also provides a procedure for detecting, recording and mapping the operating region (R) wherein the device (10) is operated.
