Activity Log: Virginia Tech (Hours 3 - 4)
- The team decides to use the hose from the pool items to help transfer water from the materials bin to the bucket (figure A).
- While the Hoakies work on the hose attachment, Buzz joins four 10" motor-and-wheel assemblies to create the base frame of the robot (figure B).
- Graham cuts notches into the sides of the materials bin with a pneumatic saw and a file. He then stretches a swimming cap over the open end of the bin and secures it on the notches he just made (figure C). This covering prevents any spillage as the lifting arm pivots and ensures that all the water in the bin is diverted through the hose into the bucket. A test of the mechanism proves successful.
Activity Log: Southern Utah (Hours 3 - 4)
- Working on the robot's upper framing, Tracy cuts various lengths of aluminum for David. Together they work out the mechanics of the lifting arm (figure D).
- In order to protect the electronics from moisture, Brian fashions a waterproof canvas out of an inner tube from the pool items (figure E). He cuts the tube into four crescent sheets and glues them together. Each piece overlaps the other, like roof tiles, so that water is completely sealed off from the electronics platform.
- Southern Utah connects the pool hose to the lid of the bucket and attaches the arms and sprockets to the pivoting shaft (figure F). Now they must carefully work out the proper mechanics of all these components before completing the construction.
- Tracy drills bolt and drive shaft mounting holes into a sturdy two-by-one piece of extruded aluminum. He inserts these motor mounts into the upper framing, where the sprockets, lifting arms and bucket will be attached.
