Underactuated Self-Balancing / Smart Car KitProduct Brochure
Single-sided Balanced Block
B650 / B790 Single-point balance
Product Details

Product Overview
Balancing blocks on a single edge or point to achieve self-stabilization is a common experiment in automatic control courses: B650 has a simple structure and low entry barrier; B790 requires three motors to work together with more complex algorithms.
Both products offer open-source core control code and schematics, supporting PID and LQR control methods. Ideal for continuous experiments ranging from parameter tuning to state-space design.
