Values must not be hardcoded

[AshishRamesh]

removed hard coded values

The coordinantes 0,0 are valid

[AshishRamesh]

ive fixed it , now uses the time stamp instead so avoids filtering any valid coordinates.
Side note while looking for possible solutions i noticed that most service robot exercises use hardcoded values (init coords and start coords) to get around this. Should i rectify them in another pr ??
