You may want to enhance its capability to detect obstacles, navigate by waypoints, in other words make it work autonomously. An autonomous mobile robot is capable of navigating in an uncontrolled environment without the need of human guidance.

How To Detect Objects with HC-SR04 Ultrasonic Sensor, Arduino and millis

Obstacle detection is applicable to any robot that moves from an initial position to a goal position avoiding any obstacle in its path. The process of detecting obstacles is applied for a variety of robots, including a mobile robot and a robot arm. In this tutorial, you will learn how to use the HC-SR04 sensor with an Arduino board and determine the detection range of the sensor in certain conditions. Different projects may have different requirements.

Alternatives To Standard Arduino IDE: Which One To Choose?.

A List With Free Alternatives To Standard Arduino IDE Ready To Be Downloaded And Used In Sketching And Building Arduino Projects. The Arduino IDE is absolute genius and it's the perfect tool for a beginner. But, what happens if you want more, if you want an alternative to this, a powerful development tool able to bring you advanced features in code efficiency and speed of development.

How To Make Accurate ADC Readings with Arduino

Even one failure of a sensor can result in a disaster for your robot. In this post, I explored the method to make accurate ADC readings with Arduino to eliminate the failures of analog sensors used in robotics applications. This method is applied to analog sensors such as temperature, light, etc. For accurate readings, you need to take into account the actual value of the power supply voltage. Of course, I need a development board to test this method.

How to pick the right Bluetooth module for your DIY Arduino project

Wireless communications are becoming a key driver of DIY and maker culture in robotics. As the use of smartphones continues to grow and mobile devices are becoming an essential tool in communication, the easiest way to control an Arduino board seemed to be using the Bluetooth technology. Using a simple Bluetooth module, you can send and receive information from sensors to Android or iOS device. The number of applications in this area is limitless.

11 stunning DIY hexapod robots

After getting some level of electronics and programming skills using different controllers, anyone decides to build a robot something more interesting than a simple robot with wheels. Into the DIY culture, anyone can build a variety of robotic projects without worrying about becoming boring. For instance, in this case are the exciting hexapod robots. The hobbyists' community comes with plenty of projects and platforms to enhance the experience and improve the skills of other community members.

How to Use InfraredIR Sensors - Tutorials

In this article, I go further in the series of articles that explore sensor types used in robotic applications. In another article, I make an overview of infrared sensors while now the main topic is to help users to learn how to interface and programming infrared sensors for different applications like color detection, line following, or distance calculation. The principle of operation of an infrared sensor is based on infrared light that is reflected when hitting an obstacle.

How To install ROS Kinetic on Raspberry Pi 3 Ubuntu Mate

The ROS framework is compatible with a short list of Linux distributions. Neither the hardware side is not better. There are just few hardware architectures compatible with ROS. Raspberry Pi is one of the development boards compatible in terms of hardware with ROS. So, I thought to install ROS Kinetic on the Raspberry Pi 3 running Ubuntu Mate. But only a certain version of Ubuntu Mate is compatible with ROS and Raspberry Pi 3, it is about the Ubuntu MATE for Raspberry Pi 3.

How to pick the best temperature sensor for your Arduino project

Do you want to find the right sensor for your DIY project based on the Arduino microcontroller Well, finding the right sensor requires research and to facilitate this process, you'll find all the info you need in this article. But if there's one thing better in the DIY culture than theory it's practice. IntroductionTemperature sensors are widely used to sense the temperature in an environment. They all function in a similar way, but have slightly different features.

Interfacing and Programming Ultrasonic Sensors - Tutorials and Resources

It is essentially to give your robot eyes for preventing crashing. Ultrasonic sensors, also known as transducers, have a similar working system as a radar or sonar by interpreting the echoes of radio or sound waves generated by the sensor. In this way, a robot can detect obstacles and the distance to obstacles.

Robotics Simulation Softwares With 3D Modeling and Programming Support

In general terms, simulation is a process to develop a virtual model capable of emulating the real-world process. Applied in robotics, the simulation process is used to create a virtual model of a robot including the design and programming code. Most popular robotics simulation software are used in 3D modeling and rendering in a virtual environment that imitate the real environment of the robot. For example, we can simulate a robotic vacuum cleaner in a house.

How to build your printed robot arm assistant

The printable robot arm This project reminds me of the Tony Stark's robot arm assistant involved in his projects to save the world. The miniature robot arm for your desk has been developed by Andreas H lldorfer and is inspired by industrial robots. The real intention is to build an affordable robot arm, and the cheapest solution was to use a 3D printer. The result is an ABS plastic robot arm with a weight of 1Kg without the gripper and the base.
