Introduction¶

What is Cake Robot Library?¶

Cake Robot Library (CRL) is a Python package that provides an easy and efficient framework for robot programming. It is also the core of Cake Robotics cloud platform.

CRL wraps ROS functionalities and integrates them with opt-in Cake cloud services. From the outside, CRL is just a set of declarative classes and functions that can be used to create maintainable robot programs.

An Example¶

This simple example can illustrate how CRL helps you write robot code. Can you guess what happens if we could run this code in a robot?

import cake
import time

robot = cake.Robot()

while True:
    robot.wheels.set_speed(2)
    time.sleep(5)
    robot.wheels.set_speed(-2)
    time.sleep(5)

You’re right. The robot will simply move back and forth indefinitely.

In the real world, you can’t just write a code like that and push it to a robot. It is true that the code suffices to define the task but you also need a lot of code to manage hardware.

But do you?

With CRL, you don’t. In fact, that code is a real program and you can run it as it is, using CRL.

Of course, you still have to briefly define your hardware for CRL (we’ll catch on that later), but you no longer have to manage hardware in your code. Your code will only describe the task, and it will just work. Piece of cake!
