For our experiment we decided to test the limitation and accuracy of the ultrasonic sensor. We started off by choosing three different objects to test our sensor on. We agreed on a small cereal bowl, a rubix cube, and a deodorant stick. First of all, we moved the object around the sides of […]
We Chose to explore the Ultrsonic sensor
David Carratu Paul Gelhaus Ultrasonic Sensor Investigation For this investigation of the EV3 Sensors we decided to experiment with the Ultrasonic sensor since we believed that it is easily applicable to autonomous navigation. We wanted to test the tolerances and limitations of this sensor to better understand how the ultrasonic sensor works and in […]
Lucy Pavlovich, Kevin Destin Sonar Sensor Testing When we were thinking about how to tackle this project, Lucy brought up the point of how the fact that the sonar sensor is made up of a receiver and an emitter could cause an imprecision in the value measured by the sensor. Essentially, the […]
As we try to investigate the limits and functionalities of the gyro sensor in the EV3 kit, the first question that we came across was, what exactly does the gyro sensor even do? This was simply answered by hooking up the gyro sensor to the EV3 brick and see what the output is in the […]
Duc Nguyen and Julia Ferreira Robotics Color Sensor Investigation For our project, we decided to test the color sensor, particularly the RGB color detector. We set up the sensor by attaching it to the brick so that the bottom of the sensor touches the ground, then we stabilized the brick by putting legs […]
(Faizan Muhammad and Adan Leos) Introduction: We tested the ability of ultrasonic sensor to detect the distance from an object when the object is oriented at different angles. The fact that it detects reflected sound means that it should be unable to detect objects oriented at certain angles because the sound waves do not reflect […]
We were testing the color sensor and how easily it is affected by its environment. We placed four different colored notebook (orange, light blue, dark blue, and red) half an inch away from the sensor, and then read it’s RGB value in different environments. We tested in direct sunlight outside, direct sunlight inside, shade […]
For this project, we tested the range of the light sensor on various colors. We used ten different colors, ranging in brightness. To perform our tests, we put our sensor at the end of a tape measure, and at increments of a half inch, we noted what the sensor was reading for each specific color. […]

We first attempted to find a relationship between the reflected light value from the light sensor and the distance away from the light sensor. However, using a standard piece of chipboard, the reflected light scaled value had no discernable relationship to distance, even when outliers were excluded. So, we changed our investigation to one of […]
For this project we decided to investigate some of the sensory properties of the ultrasonic sensor. We went ahead and tested some of the various limits of the sensor. These include: Maximum detection range (Two different sized papers) Minimum detection range Detection of different materials (Glass pane, window screen, cloth, and tissue paper) Detection of angled surfaces […]
