-=== Using mappers ===
+=== Using Mappers ===
 
+'''Mappers''' are simple objects helping to adapt params from '''!RemoteControl''' '''Components''' output to '''Robot'''/'''!GaitSequencer''' methods input.
 
+For example, to control the robot walk, we can create a '''Joystick''' component with 3 axes: X, Y, RZ.
+
+But the '''!GaitSequencer''' '''walk()''' method expects '''speed''', '''direction''', '''length''' and '''angle''' params. Using the '''!MapperWalk''' mapper, you can compute all these params from X/Y/RZ axes, and send them to the '''walk()''' method. That's what we did in the [[Tutorials|tutorials]].
+
+See [source:/py4bot/inputs/mappers/mapper.py] to see how this mapper is defined.
+
+Of course, you can define your own '''Mappers'''.
