A configurable pothole for testing autonomous cars – Part 4

This is our last post in a four-part series about building a configurable pothole for testing autonomous cars. We built the configurable pothole prototype with five independent Scotch Yoke units controlled by servo motors and an Arduino UNO. For more background, please read the previous post of this series where we discuss how to interface Scotch Yoke units with Arduino UNO and […]

A configurable pothole for testing autonomous cars- Part 2

Autonomous cars are becoming a reality. We were wondering how testers could contribute to overcoming the engineering challenges related to self-driving cars. In the previous post of series, we discussed how self-driving cars work, typical sensors used in self-driving cars and some unconquered engineering challenges for self-driving cars. At the end of the post, we decided pothole detection was a suitable […]

Testing the Fitbit heart rate monitoring system: Part 2

In this post, we outline a cheap and creative way to perform repeatable and controlled tests on the Fitbit heart rate monitor. Our test has a reasonable degree of accuracy. We hope it helps the Fitbit developers rapidly test their prototypes. To be clear: thorough, accurate and precise testing is needed in the later stages of development. The test outlined […]
