# Coding - Simulate a robot Write a program that simulates the movements of a robot. The robot can have three possible movements: turn right turn left advance The robot is placed on a hypothetical infinite grid, facing a particular direction (north, east, south, or west) at a set of `{x,y}` coordinates, e.g., `{3,8}`, with coordinates increasing to the north and east. Create a Class `Robot` that contains a method `execute` which given a number of instructions will calculate the robot's new position, and the the direction in which it is pointing. ## Example The letter-string "RAALAL" means: Turn right Advance twice Turn left Advance once Turn left yet again Say a robot starts at `{7, 3}` facing north. Running this stream of instructions should leave it at `{9, 4}` facing west. ## Inputs and Outputs The argument of the `execute` is `string` in the format `X Y BEARING COMMANDS`. The method should return a one-liner `string` in the format `X Y BEARING`. In the example above, the `execute` argument would be `7 3 NORTH RAALAL`, and the method should return `9 4 WEST`. ## Tests ### Javascript Tests are using Jest. To run them, use the following command: ```js npx jest robot-simulator.spec.js ``` ### Ruby Tests are using Minitest. To run them, use the following command: ```ruby ruby -Ilib:test test_robot_simulator.rb ``` ### Python Tests are using PyTest. The test expect a module named `robot.py`. To run them, use the following command: ```python pytest test_robot_simulator.py
# Coding - Simulate a robot
Write a program that simulates the movements of a robot. The robot can have three possible movements:
turn right
turn left
advance
The robot is placed on a hypothetical infinite grid, facing a particular direction (north, east, south, or west) at a set of `{x,y}` coordinates,
e.g., `{3,8}`, with coordinates increasing to the north and east.
Create a Class `Robot` that contains a method `execute` which given a number of instructions will calculate the robot's new position, and the the direction in which it is pointing.
## Example
The letter-string "RAALAL" means:
Turn right
Advance twice
Turn left
Advance once
Turn left yet again
Say a robot starts at `{7, 3}` facing north. Running this stream of instructions should leave it at `{9, 4}` facing west.
## Inputs and Outputs
The argument of the `execute` is `string` in the format `X Y BEARING COMMANDS`. The method should return a one-liner `string` in the format `X Y BEARING`. In the example above, the `execute` argument would be `7 3 NORTH RAALAL`, and the method should return `9 4 WEST`.
## Tests
### Javascript
Tests are using Jest. To run them, use the following command:
```js
npx jest robot-simulator.spec.js
```
### Ruby
Tests are using Minitest. To run them, use the following command:
```ruby
ruby -Ilib:test test_robot_simulator.rb
```
### Python
Tests are using PyTest. The test expect a module named `robot.py`. To run them, use the following command:
```python
pytest test_robot_simulator.py
```
