Robot system and color control method

A robot system, comprising at least two articulated robots and a server, wherein

• each of the at least two articulated robots comprises a robot controller, a plurality of rotary joints, and a plurality of light-emitting devices, each of the light-emitting devices being arranged at the corresponding rotary joint of the plurality of rotary joints;
• and
• the sever comprises a controller, a storage unit, and a display unit, the storage unit storing a plurality of instructions executable by the controller and storing a visual programming language (VPL) library comprising a plurality of VPL blocks;
• wherein:
• the at least two articulated robots and the server are connected to a communication network;
• the at least two articulated robots comprise a first articulated robot and a second articulated robot;
• the server is configured to use the controller to execute the instructions from the storage unit to run an integrated development environment (IDE), and use the display unit to display a graphical user interface (GUI) of the IDE, the GUI being configured to provide a VPL tool;
• the server is configured to use the VPL tool to select a first initial VPL block and a second initial VPL block from the VPL library, the first initial VPL block corresponding to the first articulated robot, the second initial VPL block corresponding to the second articulated robot, the server establishing a first connection based on the IDE with the first articulated robot over the communication network after selecting the first initial VPL block, and the server establishing a second connection based on the IDE with the second articulated robot over the communication network after selecting the second initial VPL block;
• the server is configured to acquire first color information indicating a first color from the first initial VPL block, and acquire second color information indicating a second color from the second initial VPL block, the second color being different from the first color;
• the server is configured to send the acquired first color information and the acquired second color information to the first articulated robot and the second articulated robot respectively via the first connection and the second connection;
• the robot controller of the first articulated robot is configured to generate a first color instruction in response to the received first color information to control the plurality of light-emitting devices of the first articulated robot to display the first color;
• and
• the robot controller of the second articulated robot is configured to generate a second color instruction in response to the received second color information to control the plurality of light-emitting devices of the second articulated robot to display the second color.
