Control method for stair climber

A control method for a stair climber comprising:

• a support frame;
• a motorized mechanical group configured to move the stair climber, the mechanical group being stably coupled to the support frame;
• a stabilizing element operatively coupled to the support frame;
• a first sensor operatively coupled to the support frame and arranged so as to detect a presence of steps during a descent process;
• a processing and control logic unit operatively connected with the sensor, the stabilizing element, and to the mechanical group,
• the control method comprising:
• controlling the descent process with at least the following phases:
• a first descent phase, in which the processing and control logic unit commands the mechanical group to cause the stair climber to advance until the first sensor detects a presence of a first step;
• a second descent phase, in which the processing and control logic unit stops the mechanical group, thereby interrupting an advancement of the stair climber;
• a third descent phase, in which the processing and control logic unit commands an extraction of the stabilizing element so as to arrange the stabilizing element according to an operating configuration in which a weight of the stair climber is at least partially supported by the stabilizing element;
• a fourth descent phase, in which the processing and control logic unit commands the mechanical group to cause the stair climber to advance until the first sensor (11) detects the presence of a second step;
• a fifth descent phase, in which the processing and control logic unit commands a retraction of the stabilizing element so as to arrange the stabilizing element according to a rest configuration in which the weight of the stair climber is supported by the mechanical group;
• and
• a sixth descent phase, in which the processing and control logic unit commands the mechanical group to cause the stair climber to advance along a descent.
