  5. align the shaft as shown in the picture
  6. place the D shaped pieces (e) on the shaft and apply a small amount of glue to the tabs.
  7. Insert so the large gear fits in the slot of the surfboard.
  8. Then screw the cam hubs (f) onto the inside of the legs so that they are on the same side as the “toes”.
  9. attach the small gear (m) to the motor (l) carefully as the shaft is keyed with a D shape on the opposite side to the winder
  10. put the two remaining screws (j) up through the body with the nuts on the side of the robot with the bell shaped pieces
  11. place the motor on the robot and slot the bracket (g) over it with the bolts sliding into the holes ensuring that the hole in the bracket aligns with the hole in the top of the bells
  12. push the cam hubs on to the shaft with the left hub pointing up and the right hub pointing down
  13. attach the large bolt and screw (n) to the top of the frame through the large slot in the legs, the two bell shaped pieces and the motor bracket using the spacers provided.
