The DF Robot 5 DOF Robot Arm kit is a high-quality robotic arm that you can assemble yourself. With heavy duty servo motors and sturdy aluminum parts this inexpensive arm is perfect for your robotics experiments
Follow along as I assemble the robot arm. I’ll also build a simple robot arm controller based on the Arduino Nano and the PCA9685 16-channel PWM module.
Learn to use the popular nRF24L01 radio modules with an Arduino, using the RadioHead library.
In this article we will conduct several experiments sending data between two Arduinos with the nRF24L01. We will then take what we have learned and build a wireless joystick controller for our robot car!
I’m sure you have seen those inexpensive robot car chassis kits, the ones that come with two 6-volt motors. They are great fun and very useful and they even come with a couple of speed encoder disks (those little black circles full of holes). Problem is, no one tells you how to use them!
Let’s resolve that and build a robot car with speed sensors. Along the way we’ll learn how to use Interrupts, a valuable programming technique.
The MeArm is a small robot arm that was originally designed as a teaching device for schoolchildren. Despite its toy-like appearance it is also an excellent tool for serious robotics experimenters who would like to develop software and control systems for robotic arms without a large hardware expenditure.
Robots are the ultimate experimenters project. Nothing else lets you unleash your creativity more than designing a robot. And now with the availability of things like the Arduino and Raspberry Pi along with a wide assortment of mechanical parts and the ability to make your own with a 3D printer, robots have become a project that any dedicated experimenter can work on.
There are so many components and design considerations that must be taken into account when building a robot, This can often be overwhelming, especially when you’re creating your first automated device. This article should provide a firm foundation for getting started on your first (or next) robotics project.
