Team 8 – Gunnar and Vivek
- Two touch sensors
- Low ultrasonic sensor
- Narrow design to avoid pillars
- Have the 45 degree turns very accurate
- Go forward and touch the wall
- Turn left about 40 degrees
- Follow the line
- Stop at the end of the line
- Pick up the robot and place it in Area #4
- Move forward and stop in Area #5
The second picture should be first.
Robot Triathlon – Team 8 – Gunnar and Vivek
Have a robot start behind a line and of a clap. The robot must then go until it come close to a wall (ultrasonic sensor), turn 90 degrees. Then, go forward until it touches a wall then turn another 90 degrees toward the starting/finishing line and have it stop using the light sensor.
Steps + Commands:
1) Start – Wait for a clap
2) 1st Wall – Go forward until 7 inches away from first wall
3) 2nd Wall – Turn Left 90* and go straight until robot touches wall.
4) Line – Go straight until light sensor senses line
5) Stop – Stop when robot sees line.
NXT Program:
Wait block Sound above 99
Motor BC forward until Ultrasonic senses wall 7 inches
Motor B reverse Motor C forward – turn 90*
Motor BC forward until touch senses wall.
Motor B reverse Motor C forward – turn 90*
Motor BC forward until light sensor senses lower than 40.
Motor BC STOP
Reflection:
Gunnar and I didn’t need to do the challenge because our idea was chosen for the homemade challenge. We still have the directions to program. After I looked at people’s robots attempting the challenge, it was clear that this challenge was harder than I thought it would be. The best team completed it on their forth try.

- Describe the four parts of a circuit
Power Source, Path, Electrical load, Switch
- Name an example of a circuit
A switch board connected to a light
- Categorize the parts of a given circuit
Wires
Transistor
Power
- Differentiate between Insulators, Conductors and Semiconductors
Insulators keep electricity from going on, Conductors do the opposite. Semiconductors do both.
- Name an examples of Insulators, Conductors and Semiconductors
Rubber, Copper, Transistors.
1) We kept the arm the same as the design in the book. We later saw that having a longer arm would have helped with the momentum and kinetic energy.
2) We saw a group with a longer arm make a hole-in-one with ease because the energy transferred to the ball was greater. Structural Integrity also helped transfer energy instead of losing it.
3) Faraday’s Law: Like Newtons law and Enthalpy conversions for Chemistry. Energy that is reversible.
