The RoboClaw is a rather sophisticated motor controller with a wide range of features and functionality. This Application Note will be a broad overview of the board, its features and tips on its usage.
Standard Serial Bus Operation with Arduino
Some robotics projects will require the use of more than one motor controller at a time. RoboClaw supports this type of operation and it’s straightforward to configure and wire.
Using Multiple RoboClaws with Arduino
Some robotic projects make use of more than one motor controller. The RoboClaw is engineered to be used in this fashion with the use of a microcontroller like an Arduino.
Analog Joystick and RoboClaw
The RoboClaw has several useful control methods, one of them being analog control. With analog control you can use a variety of user interface options so long as they output an appropriate analog voltage. In this Application Note we’ll be using an analog joystick to control two motors with the RoboClaw in analog mode.
PID Control and Motor Controllers
Motor controller like the RoboClaw used feedback from sensors like encoders to maintain the speed and position of motors. Internally, a system called a PID controller is used to maintain these values at their given setpoints. In this App Note we’ll be looking at the what, why and how of a PID controller.
Pololu Encoder Wiring
Encoders allow the RoboClaw to provide accurate and consistent speed and position control of motors. In this Application Note we’ll be wiring a common motor and encoder combination to the RoboClaw.
Reading and Troubleshooting RoboClaw Errors
Things don’t always go as planned when operating your robots and problems can occur that need to be dealt with as they come up. Thankfully, the RobClaw motor controller has a handy set of features that alerts you to problems that may crop up. We’ll be looking in to how to read the error messages of the RoboClaw via the onboard leds and how to diagnose the problems they are associated it.
Selecting the Proper Battery
Selecting a battery for your robotics projects is vital in ensuring your robot will have the power and endurance you’re looking for. There are several properties of batteries you’ll need to be aware of make the right choice for your project. After reading this App Note you’ll be informed enough to make the right decision.
RoboClaw Battery Eliminator Circuit (BEC)
Often a robotics project will need multiple voltages for different parts. A Battery Eliminator Circuit is one way to have multiple voltages present in your build without the need for a second battery.
Analog Control with RoboClaw
There are many control schemes available with the RoboClaw. One of the simplest control schemes is analog control. Analog control allows for an analog voltage to control motor speed and direction.
