Main goals of this project included: design and optimization of the mechanical construction of the robot and its final assembly; solving the forward and inverse kinematics equations and calculation of the working area; simulation of joint trajectories for linear movement of the end effector; writing kinematics functions in C and their implementation in the control system. The project was carried out successfully, resulting in a working prototype. The robot is capable of manipulating objects at a speed of 2m/s with an efficiency up to 75 cycles per minute (25/305/25 test).

Shape of the working area calculated using only the mathematical properties of the construction
Shape of the working area calculated using the mathematical properties of the construction and its mechanical limitations
The 25/305/25 Test was performed using a working prototype. This metod of measuring the efficiency is comonly used in the industry. (ABB, Fanuc,Mitsubishi, Festo)
Obtained result is equal to 75 cycles per minute.
It is 50% of the efficiency of the Festo Tripod manipulator which offers 150 cycles per minute in the same test.
