Product Overview
The inverted pendulum is a classic multivariable, non-linear, strongly coupled, and naturally unstable system. Its research effectively demonstrates key control challenges such as non-linearity and robustness. This product balances performance and cost through hardware optimization and complete dynamical analysis using PID/LQR algorithms.

01 | Fully Open-Source & Secondary Development Support
The inverted pendulum is a classic under-actuated control system with complex hardware and software integration. We provide 100% open-source code, allowing developers and students to skip the tedious baseline setup and dive straight into secondary development for intelligent control and advanced robotics projects.

02 | Classical PID & Model-Based LQR Algorithms
Our product supports two distinct control strategies for pendulum stabilization:
-
Classical PID: For intuitive, error-based feedback control.
-
Model-Based LQR (Linear Quadratic Regulator): For advanced, optimal control performance.
-
Comprehensive Docs: Includes detailed tutorials to guide you from theory to practice, step-by-step.

03 | Industrial Grade Performance at a Hobbyist Price
Traditional lab-grade inverted pendulum platforms often cost thousands of dollars and occupy significant space. Our solution offers research-grade performance in a compact, budget-friendly design. It is the ideal choice for laboratories and educational institutions looking to maximize their research capabilities without budget or space constraints.
04 | Superior Robustness & Disturbance Rejection
Engineered for high stability, the system features excellent robustness. It can withstand external physical interference and rapidly recover its balance, ensuring reliable performance in dynamic environments.

05 | Intuitive Manual Movement Control
The controller features integrated tactile buttons for direct interaction:
-
Linear Inverted Pendulum: Control left/right lateral movement.
-
Rotary Inverted Pendulum: Control clockwise/counter-clockwise rotation.

06 | Intelligent Auto-Zero Calibration
Simplify your workflow with the built-in homing function. With a single click, the system automatically detects and updates its mechanical zero position, ensuring precision every time you power up. (Note: This specific feature is supported on the 2nd-Stage Linear).

07 | Revolutionary PID Tuning System
We have redefined the debugging experience to be as plug-and-play as possible:
-
Hardware Tuning: Adjust PID parameters directly via on-board buttons.
-
OLED Monitoring: View real-time parameters on the integrated display.
-
Visual Analytics: Export and analyze response curves through our dedicated host computer software.
Low Entry Barrier: Even without prior knowledge of C-language, STM32, or complex IDE configurations, you can still perform PID tuning. Simply connect via a Type-C cable to start optimizing. (Note: The 2nd-Stage Linear utilizes LQR algorithms and does not support the manual PID button-tuning feature).
