Calculation of the diameter of the drive screw intended for moving the robot in the greenhouse

To accurately perform all operations by an autonomous robot in a greenhouse, it is necessary to correctly determine the diameter of the lead screw. This article presents a method for calculating the diameter of the lead screw, which takes into account the simultaneous effects of bending and torque on the lead screw. When the lead screw is subjected to bending torque, it is necessary to consider the percentage distribution of the autonomous robot's mass on the limiter and the lead screw, as well as the method of attaching the telescopic rod to the moving platform and the positioning of the autonomous robot relative to the support trolleys. When the bending moment is applied to the lead screw, the power of the servo motor and its angular velocity, as well as the material of the lead screw, are taken into account.
