The paper demonstrates use of wireless sensor as input data source for fast real-time automatic control. Fast, underactuated and highly unstable inverse triple pendulum system is controlled on the basis of values measured on the pendulum arms and wirelessly transmitted to the controller. The presented solution working in 2.4 GHz band and based on Atmel SAM R21 SoC on the sensor side and Atmel AT86RF233 transceiver on the controller side delivers data from 2 IRC sensors and 3-axis gyroscope with latency as low as 350 us.
