About this item
- A rotary (Furuta) inverted pendulum you build in an afternoon and then use for a whole course.
- A stepper motor turns a horizontal arm; a free pendulum hangs from its end, and a magnetic encoder reads its angle 1,000 times a second.
- The firmware swings the pendulum up from rest and holds it upright with an LQR controller, and every gain is exposed over USB so you can tune it, log data and test your own controllers.
- It covers the same ground as commercial teaching rigs costing several times more: system identification, linearisation, pole placement, LQR, energy-based swing-up and sim-to-real comparison.
- The guide includes a Python model of the rig so you can design in simulation first and then run the same controller on the hardware.
- Everything is included except a computer and a USB cable: controller, stepper and silent driver, encoder, bearings, 12 V supply, the printed frame and arm, a pre-made wiring harness, screws, the build guide and the firmware.
