A three-axis open source desktop robotic arm controlled by an STM32 microcontroller, suitable for teaching and secondary development. It has the following characteristics:

       Powerful function: It can support multiple motion modes such as point to point, point to straight line, straight line to straight line, etc., as well as DO output, DI input and other external signal control. It can also support the conversion of joint coordinates and world coordinates.

       High expandability: it can replace the claws or suction nozzles to realize the function of grabbing or sucking different items. It can also support multi-machine connection and work in conjunction with the production line.

       Portable operation: It is equipped with an industrial-grade touch screen teaching pendant, which supports manual teaching and drag teaching. It also provides a parameter setting interface in the command state to facilitate users to adjust the performance of the robotic arm.

       High precision: Its repeatability can reach 1mm, ensuring the movement accuracy and stability of the robotic arm.

       Open source sharing: It provides open source C language motion control algorithm code to facilitate users to learn and modify.
