5.1 System Usage Instructions

1. System Overview

The myCobot Pro 450 robot control system is a powerful and intuitive robot software platform designed to help users easily program, control, and monitor robots. Whether you are an engineer, teacher, or operator, you can quickly get started with this system and implement various automation tasks with the robot.

The system mainly consists of the following parts:

• myStudio Pro (WebApp): A browser-based visual programming and control interface that supports remote operation and advanced feature development.
• MiniRobot (Local Control Interface): A simple local control panel, suitable for quick on-site control and teaching.
• Network Control System: Supports a secure control architecture with multiple network interfaces (LAN1, LAN2, WLAN), ensuring the isolation of control traffic from internet traffic.
• Serial Communication Interface: Supports industrial communication protocols such as RS485, facilitating connection to external devices such as PLCs or sensors.

2 Introduction to MiniRobot

MiniRobot is a locally controlled interface designed for the robot, acting like a "remote control." With 4 buttons and a small screen, it's easy to operate, requires no computer, and works offline.

Main functions:

• Local Trajectory Recording: Record motion paths using buttons or manual guidance, with an accuracy of ±0.1mm.
• Simplified File Management: Delete or directly execute saved program files.
• Fast Execution Control: Supports single or loop execution modes, provides a progress bar display, and offers quick emergency stop response.
• Status Inquiry: View real-time robot position, speed, load, and other status information.
• Basic Configuration: Supports speed settings, safety parameter adjustments, and zero-point calibration.
• Communication Forwarding: Supports UART/SPI data relay for convenient interaction with local devices.

Features: Simple operation, fast response, and support for offline use, making it suitable for quick on-site debugging and teaching.

3 myStudio Pro Introduction

myStudio Pro is a feature-rich web-based control platform suitable for advanced development and remote management.

Main functions:

• Graphical Programming (Blockly): Quickly write robot programs by dragging and dropping code blocks, supporting motion control, logical judgments, and sensor interaction.
• Virtual Trajectory Planning and Drag-and-Drop Teaching: Plan paths in a 3D simulation environment, supporting manual dragging to record trajectories and preview motion effects.
• File Management: Remotely upload, download, and manage program and trajectory files, supporting categorized browsing and a recycle bin function.
• Execution Monitoring: View the robot's execution status in real time, supporting control operations such as start, pause, and stop.
• Firmware Updates and Tutorial Integration: One-click check and update of system firmware, with built-in video tutorials and operation guides.
• Network Configuration Integration: Manage network permissions through a user interface, supporting whitelisting and permission toggling.

Features: Comprehensive functionality, strong visualization capabilities, suitable for remote collaboration and complex task development.

4 Network Port Introduction

The system supports three network interfaces, each used for a different purpose, ensuring both security and network flexibility.

• LAN1 (Control Network):

  • Purpose: Dedicated to the transmission of robot control commands.
  • Features: Static IP configuration, not connected to the internet, ensuring real-time control and security.
  • Applicable Scenarios: Local high-real-time control, such as motion commands and sensor data broadcasting.

• LAN2 (Wired Internet Interface):

  • Purpose: Connects to the internet for remote access, software updates, etc.
  • Features: Supports DHCP for automatic IP address assignment and allows manual configuration of static IP addresses.
  • Applicable Scenarios: Remote debugging, firmware upgrades, cloud service access.

• WLAN (Wireless Local Area Network):

  • Purpose: Wireless connection to the internet, functionally equivalent to LAN2.
  • Features: Supports Wi-Fi connectivity, suitable for mobile device access.
  • Applicable scenarios: Mobile device control, temporary network access.

Security notice: By default, the system only allows control via LAN1. Control functions via LAN2/WLAN must be manually enabled and configured with authentication to ensure secure operation.

Port Configuration Table

Security Mechanisms

1. Permission Switch Control

• Remote control for LAN2 and WLAN can be switched on or off independently.
• Default state: Both are off (most secure).
• When enabled: The control port is simultaneously bound to the corresponding network.

2. Key Security Measures

• Broadcast Port Locking: Ports 8001 and 8002 will only be used on LAN1.
• Mandatory Authentication: Remote access requires account login.
• IP Whitelisting: Only trusted devices are allowed to connect.

Network Configuration Recommendations

5. Introduction to Serial Ports

The system has a built-in RS485 industrial serial communication interface, which is mainly used to connect external industrial equipment such as PLCs, sensors, and frequency converters to achieve stable and reliable data exchange and command control.

This interface is based on the Modbus protocol (a standard communication protocol widely used in the industrial field), which allows for monitoring the robot's status, controlling its motion, and setting its parameters through simple read and write commands.

Main Applications:

• Read Robot Status: Such as joint angles, end effector coordinates, motion mode, I/O status, etc.
• Send Control Commands: Control robot movement, start/stop, mode switching, etc.
• Connect to External Devices: Interact with industrial equipment such as PLCs, touchscreens, and sensors to build automated systems.

Typical Use Cases:

• Robotic arm movements are centrally scheduled by a PLC on the production line.
• In conjunction with vision sensors, positioning and grasping are achieved.
• Local control via serial port in environments without a network connection.

Communication Configuration Recommendations:

• Baud Rate: 115200 (Default, compatible with most devices)
• Protocol: Modbus RTU
• Tools: Common serial port tools such as Modbus Debug Assistant and SSCOM can be used for testing.

Note: Before use, please ensure that the external device supports the Modbus protocol and set the corresponding slave address (default is 45) and register address. For details, please refer to the function list in the protocol manual.
