P.A.A.M.I.


 
Here are the latest images of our
      Priority Arbitration wanna be. The addition of the Arbitration
      processor is very soon and we can implement the first two levels
      simultaneously.

 Rear Bumper
      assembly. Two plates of lexan allow for rear impact detection
      on either right or left sides.
 Frontal
      view, the two plates of lexan cover most of the front on each
      side, and the U shaped bridges protect the frontal sensors and
      pivot bolts from a direct impact.
 The
      top cover is now installed for the first time giving the overall
      round appearance. It is hinged on the top end with brass tiny
      hinges.
 The two bumper
      plates hinge in the middle of each plate on a shaft with a spring
      tension and a capping nut on the outside. The entire bumper easily
      tilts on this pivot point and allows the bumpers to press one
      of eight switches on the front.
 Overall
      view again. See the first MOVIE (880K) of Pammi moving autonomously
      with the new bumpers !
