Radio Control

We need to be able to drive our robot with an RC controller.

• [x] RC transceiver to microcontroller: We need to be able to see input from an RC controller on a microcontroller, which will require using one of our RC transceivers (like this). This is likely going to require some (light) breadboarding, plus some reading of the transceiver datasheet. Completion Criteria: Getting the RC transceiver powered, talking to RC controller, and talking to MCU.

• [x] MCU to Jetson: We need to be able to send any data from the RC controller through the MCU to the Jetson. This is probably going to require a simple serial connection set up on both sides. Completion Criteria: can send RC data through a serial link to the Jetson.

• [ ] RC data to ROS message: Now that we have RC data, it needs to be converted to a ROS message that we can actually use to control the robot. The intention is for this ROS message to get parsed and passed to the motor controllers to drive the robot. Completion Criteria: RC data is available as a published ROS message.

• Make sure to give Arduino permission to access the serial port: https://github.com/esp8266/source-code-examples/issues/26

• Add markers to the Arduino serial data so we can know when a new set of transmitter data is being transmitted over serial.
