Goal: simple control algorithm.

Accessories:

• LEGO set
• instruction QuickStart
• software LEGO MINDSTORMS NXT

Output: Report

What to do:

1. build a simple mobile robot, and simultaneously
2. design a simple control algorithm
3. test the robot and the algorithm,
4. evaluate and draw conclusions → Report

Team organization:

• robot builder: 1,2 persons,
• algorithm development: 1,2 persons.

Caution !:

• use only blocks that you need
• do not take out too much blocks in the same time
• put all unused blocks back in proper compartments

(Builing team)

• Build a simple mobile robot i.e. according to QuickStart, your invention here is welcomed.
• Connect desired sensors on the front or side of the robot (i.e. sonar)

(Control team)

• program simple control algorithms (1-2)
• use 1 or 2 sensors
• save project files

• robot drives on its (given) way (square, circle, triangle)
• repeats this way N times
• robot stops after finding an obstacle (touch or distance sensor)
  • plays beep signal
  • backs up

• robot drives straight
• after reaching an obstacle (use sonar) it tries to avoid it
  • plays beep signal
  • make a right turn

• robot follows up a light source

• control the robot by voice signal (e.g. clapping) or touch
• example: one clap - start, two claps - stop

Test the algorithm on the constructed robot. Please, remember that after uploading program to the robot you can disconnect USB wire and let it go on the desk or floor.

• Disassemble the robot, and put all elements in the proper compartments in the box

CAUTION: do it slowly and carefully - damage is much easer during disassembly then while assembling.

Prepare a short report describing what you have accomplished during this exercise:

• what was the purpose of the robot,
• what sensors did you use and why,
• include a photo of your robot,
• include a screenshot of your program,
• describe problems and difficulties you had.
