5.  Changes to Requirements: Maximum Object Weight of 5 lbs Object Switching Time of 3 seconds Objects can fall into water in different locations (front/back) From System Level Review

6.  Suggestions to Improve Design Keep the Objects close to the surface of the water to enable faster changes Utilize Seesaw motion with fall of set of objects to enable easier lifting of other set Link lifting/lowering mechanism to enable the same power source to move both sets of objects Identify potential component vendors Simplify the Object-Blocking mechanisms to a more locally mounted device Use a Water Container as counterweight From System Level Review
