1. Analysis of the use requirements: each robot is designed according to the generation of specific requirements, and the first step of the design is to analyze the use requirements clearly and determine the parameters that need to be considered when designing, including: the positioning accuracy of the robot and the repeated positioning accuracy; The size of the load of the robot, the characteristics of the load; the number of degrees of freedom of the robot's motion, the motion stroke per degree of freedom; The working cycle or movement speed of the robot, acceleration and deceleration characteristics; The movement trajectory of the robot, the association of actions; The working environment and installation method of the robot; The operating system and life of the robot; Other special requirements.

2. The initial construction of the mechanical model: the robot can be roughly divided into gantry structure, wall-mounted structure, and vertical structure from the mechanical structure, and different structures are selected according to the requirements of the installation space, and the mechanical properties and motion characteristics of each structure are different. The subsequent design must be based on a defined structure.

3. Calculation of sports performance:

The parameters for this performance are:

Average speed: V=S/t ;

maximum speed Vmax=at,a=F/M;

Wherein: S is the exercise stroke; t is the positioning movement time; The driving force at the time of acceleration; Mass of moving objects.

4. Analysis of mechanical properties

A robot is made up of many positioning units, each of which has to be analyzed. The items that need to be analyzed are as follows: horizontal thrust Fx; Positive pressure Fz; side pressure Fy; Mechanical strength check: each positioning unit and each beam must be checked, especially the double-ended support beam and cantilever beam.
