Issuess with RAB sensor and actuator with Buzz controller for epuck model

[karthiks1701]

I tried to create a buzz controller for e-puck, by basically copy-pasting the code from the footbot buzz controller. But there seems to be a error for the range and bearing sensor used by the epuck model. Any idea how to solve it?. I also had a quick look at [(https://github.com/demiurge-project/argos3-epuck/tree/master/src/plugins/robots/e-puck/simulator)], they seem to have a bug fix for this, could that be the problem?.

The error message at the last line tells you where the error is: your XML file is missing the medium attribute. Use argos3 -q range_and_bearing to check the required XML configuration. For these requests, the ARGoS forum is more appropriate.

Thanks! Got it working
