hi every body I have been making a walking robo. Although I am successful in defining all the four directions to walk and its also working physically. But now I wanna put my project a step ahead i.e. I want to control my robo from somewhere else through internet for that purpose I have been using esp8266-01 wifi module but I am facing a lot of problems with that.
any help regarding project will be encouraged.

Can u please further explain your problem.
It seems Robo is okay… only problem controlling it wireless through Web… easier AT Command Options are also inbuilt… might come handy for debugging…

actually I have uploaded node mcu firmware and AT commands are no more responding. I need to send a string from android to Arduino via esp8266

try checking the Hardware interfacing by basic AT Commands of the module… its simple Serial Communication… UART… u’ll get plenty of working codes too…
If running some Firmware doesn’t work as expected… need to debug step by step fashion.
