As the clock begins to run out, both teams must finalize their robots and add any finishing touches. After time runs out, the competition will soon follow.
Activity Log: Virginia Tech (Hours 5 - 6)
- Ian builds the upper framing, threading a shaft through the vertices of two pieces of extruded aluminum (figure A). The actuating arm will rotate around these pivot supports.
- Graham and Ian work on assembling the structural components of the robot. Meanwhile, Chris solders the electronics together (figure B), saving his "pretty golf hands" from the dangers of drilling and wrenching. Virginia Tech is saving valuable time by using this modular approach to construction.
- Chris wires the electronics and fits them into a plastic sleeve extracted from the back of the pool chair (figure C).
- Graham and Ian fine-tune the mechanics and operations of the water collection system. Ian installs the motors using band clamps. They easily shift back and forth and allow Ian to tension the chain properly.
Activity Log: Southern Utah (Hours 5 - 6) - David continues construction of the motor-and-gear assembly that will power the lifting arm. He chooses three forty-tooth sprockets to connect to a center rod support (figure D).
- Brian installs the pool chair with the electronics onto the main chassis, first cutting away the chair legs with bolt cutters (figure E).
- With the electronics wired up and the motor assemblies installed, the robot performs a successful first test of the lifting arm (figure F).
