Could you provide the snippet where you are assigning the call back

Siti - it looks like you are using GUIDE for your GUI and, for your callback, the comments indicate that there should be three input parameters to your function signature...but the handles parameter isn't there. Try re-writing your callback signature as
function buttonForward_Callback(hObject, eventdata, handles)
and then re-run your code. Note that even the error message>@(hObject,eventdata)RRR_ROBOT('buttonforward_Callback',hObject,eventdata,guidata(hObject))
is indicating that three input parameters (hObject,eventdata,guidata(hObject)) are passed to this function.
