Team Organization
Four people, each person was dedicated to one sub-task– Hardware design (person 1) (were done in
– Software design (person 2 ) at the same time)
– Testing phase (person 3)
– Documentation (person 4)
For the next project will be split into two subtasks- Hardware design (two people)
- Software design (the other two people)

The Mechanical Design of the Robot Wheels: 3 wheels total 2 front wheels are independently powered by 2 Lego
motors And 1 small wheel is on the back

The Mechanical Design of the Robot
Gears: Only 2 gears –spur gears (front wheel driven)
Front wheel

Mechanical Design of the Robot cont. Sensors:
2 shaft encoders
-monitored the speeds of the motors
-positioned on the front wheels 2 reflectivity sensors
– Positioned on the back

Software Design of the Robot monitor_sensors() process, reads all sensors and is running
continuously. Flowchart
go_straight(distance) if (fronttape) distance=smaller; else(backTape)
distance=larger; right_turn();
go_back(~1.5ft)
align()
Success: the robot always aligns itself to the black tape if it crosses it.

Conclusions
1. At least two informal meetings are a must2. There should be “hardware freeze” date3. Successfully demonstrated the robot
alignment to the black tape.4. After the Friday demonstration we did
careful technical investigation. We found out that the major flaw of our robot was that it could not go in perfect straight line, due to hardware problems
