Third experiment with a 15 degree angle:

|
For the third experiment we placed the sensors at a 15 degree angle. This experiment turned out to be the best of the three experiments as the blind spot to the sides and the front (see Fig. 4) were minimised, and the robot was able to navigate towards light placed directly in front of it and towards light placed by its side. Though the blind spots were minimised they were still present meaning that once the robot comes too close to the light source, the light will go between the sensors (See Fig. 4). This problem could be solved using a ultrasonic distance to measure the distance to objects placed in front of the robot.

## Exercise 3: Vehicle with two light sensors and two ultrasonic sensors
|
|
|
|
|
|
#### Task
|
|
|
Vehicle 3. Combine two kinds of sensors and experiment with different motor power values dependant on the sensor output.
|
|
|
|
|
|
#### Plan
|
|
|
We intend to combine light sensors with ultrasonic sensors. As we discovered in the first experiments, the sound sensors were easily disrupted by both the sound of the electrical motors and the environment surrounding the robot, why we decided not to use them.
|
|
|
In the first experiment we will use the light sensors (red in fig. 7) to provide power to the motors (exhibitory) and ultrasonic sensors (green in fig. 7) to deduct power from the motors (inhibitory).
