Work proceeds on building the robotic stair-climbers.
Activity Log: Louisiana Tech (Hours 5 - 6)
- Louis encounters a second problem when the wheel sticks on the bolts that secure the hub to the motor. He wraps a role of electrical tape around the shaft to create a spacer and avoid one more setback.
- David constructs the mount for the third large wheel on the back of the robot. It will also serve as a skid plate.
- Buzz helps Louisiana create a balloon-popping device. At the end of an extended piece of extruded aluminum on the front of their robot, he attaches a cordless butane soldering iron with two zip ties.
- When ignited, the tip will reach temperatures around 700-degrees Fahrenheit and pop the balloon even before coming into contact with it.
Activity Log: Southern Utah (Hours 5 - 6)
- Southern Utah completes the wheel assembly using steel framing from the wheelchair and pieces of extruded aluminum.
- After cursory testing, they cut out some framing and lower the wheel assembly so that it hits the stairs sooner. This adjustment will lift the tracks higher towards each approaching step.
- Jared wires the pulse width modulators, or DC modulator speed controllers. He chooses thicker-gauge wires that will be able to source the amount of power required for large DC motors.
