Few--nucleon scattering offers a good opportunities to study dynamical
aspects of three-nucleon forces, that are momentum, spin and iso-spin dependent.
In this contribution
the experimental results of deuteron--proton elastic scattering
obtained in the course of the study are presented.
The data are compared with the state-of-the art theoretical predictions
based on the realistic bare nuclear potentials.
Recently the experimental study has been extended
to the proton--$^3\rm He$ scattering.
