Controlling a WEBcam in OpenCV on Windows

In this lesson we show how to move a frame in OpenCV, how to convert a color image to grayscale, and then how to display multiple video windows. For your convenience, I include the code below that we develop in this video.


Python 3D Graphics LESSON 3: Parameterizing your 3D Model

In this lesson we show you the importance of building a parameterized model for your 3D graphics in Python using Visual Python. You can manage large scenes unless you are doing it with parameterized dimensions. The video above takes you through it step by step. Here is the code for the parameterized box and marble we developed in Lesson 3:


Launch a Windows WEB Camera in Ten Lines of Code with OpenCV

In this lesson we show you step-by-step how to launch a WEB camera using OpenCV running on windows. In the video we show how to install OpenCV and how to write your first simple programs. Below is the code we developed in the video to launch the WEB cam.


Robotics Training LESSON 18: Obstacle Detection and Collision Avoidance

In this lesson we explore using the HC-SR04 to detect obstacles, and then avoid collisions by stopping the car. This requires a more sophisticated control algorithm for the desired distance for the car to travel. Making it even more tricky, after the obstacle is removed, the car needs to resume its programmed mission. The video shows my solution to this problem


Robotics Training LESSON 17: Measuring Distance to Obstacle using the HC-SR04

In this video lesson we show how to use the HC-SR04 ultrasonic sensor to detect the distance to obstacles in a robotic application. We use the sensor to measure the time it takes for a ping to travel from the sensor, to the target, and then back. We use this measured time, and the known speed of sound to calculate the distance to the target. This will be used in future lessons to keep the robot from running into an obstacle.
