I recently came across this "Instructable" in which the user ahmedelsayed93 has created a project to detect obstacles in front of an ultrasonic sensor using Arduino Uno board. What is so great about it you ask, the video shows the ultrasonic sensor mounted on top of a servo motor to make a Radar detector and the plot on his screen makes it look like the radar images we see in movies and weather channels .


The servo motor is controlled using an Arduino Uno which is communicating the sensor information serially to MATLAB and the data is plotted using MATLAB's built-in visualization functions.



Feel free to comment/provide suggestions to improve upon this project, I might incorporate them on my new software defined radio project that tracks airplanes.

I recently came across this summer program for high school kids that aims to teach robotics and programming. The course had a few interesting items planned like designing a line following robot, obstacle avoidance robot and a rescue robot. But the students had to one up  their teachers/mentors to show that they are the future and came up with robots that were nothing but phenomenal.


Let me introduce you to a robot that can avoid falling off a cliff. This robot uses the accelerometer on the Pololu Zumo bot to understand the slope (downward or upward) and take corrective measures so that it can stay on top of a board.



The next one is a robot that solved a maze. This robot uses the reflectance sensor to follow lines and what looks like an IR distance measurement sensor to move from start to finish. The interesting aspect was the fact that the robot does not seem to have any memory about the track and still ends up solving the maze. Enjoy the video -
