I was tasked with robot communication for Robocon 2022. The theme of the tournament was to play the game of laghori. The communication device that we were using was XBee. There was no library for XBee communication in STM32 so I had to write my own.
Above is the image of decoding and understanding XBee protocols using oscilloscope and a USB TTL device.
I wrote a library that could interface the xbee modules from the uart and delegate commands to the robots.
Here is the video of the event. This time the event occurred online due to covid restrictions.
This was for the first time in the history of 22 years Nepal was able to achieve 3rd position in Abu Robocon. We won teams of India and Thailand but lost out to Honk Kong in the semi-finals who went on to win the event.
