About this item
- The cart-pole is the problem every control and reinforcement-learning course starts with.
- This kit makes it real: a stepper drives a cart along a 400 mm linear rail with a GT2 belt, a pole swings freely on the cart, and a magnetic encoder measures its angle.
- The firmware homes the cart, swings the pole up and balances it with LQR, with limit switches and end stops protecting both ends of travel.
- Because it shares the electronics of our pendulum kit, the same firmware tools and Python model apply.
- Its Python model doubles as a simulation environment: train a policy in simulation, load it over USB and compare it with LQR on the real rig.
- Included: controller, stepper and silent driver, encoder, MGN12 rail and carriage, belt and pulleys, 2020 aluminium frame with brackets and T-nuts, limit switches, bearings, 12 V supply, printed cart and mounts, wiring harness, screws, build guide and firmware.
