MINTomat: an over-complicated bubble gum dispenser

MINTomat lets you operate two robot arms and a wirelessly controlled custom robot based on a Pololu Zumo chassis to dispense a gumball in an roundabout way. Their custom Zumo board is controlled with FreeRTOS on an NXP ARM Cortex-M4F, and uses a Nordic Semiconductor nRF24L01+ 2.4 GHz transceiver for wireless communication with other parts of the system. A few Pololu VL6180X time-of-flight distance sensor carriers are used for obstacle detection and navigation. The cabinet is illuminated with LED strips. A detailed build log is available at this blog post.
