Precise Control of ABB Robot Motors Using a Game Controller (Python Tutorial)
1. Project Background
The client requested precise control of the ABB robot using a game controller, emphasizing the need for fine adjustments to the robot’s movements. We adopted the following technical solution:
- •Control Platform: Latest version of RobotStudio 2025
- •Programming Language: Python
- •Hardware Device: Beitong Game Controller
2. Core Functionality Implementation
- 1.Hardware Connection Configuration
- •Connect the game controller to the controller via USB
- •Establish a mapping relationship between the controller signals and the robot controller in RobotStudio
3. Operation Demonstration Process
- 1.Start Control
- •Short press the A button → Motor starts (RobotStudio interface displays “Motor: ON”)
- •Status verification: Observe the motor status indicator on the control panel
- •Short press the B button → Immediately cut off the motor power
- •Safety mechanism: Exception states automatically trigger try-except protection
- •Long press the BACK button → Completely terminate the control program
4. Existing Issues and Optimization Directions
- 1.Current Improvement Items
- •Occasional interface jump exception when triggering the A button on the controller
- •Signal processing needs optimization
- •Confirm specific fine-tuning accuracy requirements with the client (e.g., 0.1mm level control)
- •Expand the analog control function of the controller’s joystick
5. Future Update Preview
- 1.Advanced Tutorial Content
- •Processing of analog signals from the joystick
- •Multi-axis coordinated synchronous control solutions
- •Motion trajectory recording and playback functions
