Criteria:
*structure: plane (a…g), spatial (h)
*cam motion: rotation (a, b, d, e, g, h), oscillation (c), translation (f)
*follower motion: translation (a, c, e - centric, b, g - eccentric), oscillating (d)
*contact cam-follower: force generated (a, b, c, d, f), shape (e, h, g)
*follower shape: pin (a), roller (c, d, f, g, h), flat (b, e)
