# pyCreate2
[](https://github.com/MomsFriendlyRobotCompany/pycreate2/actions)
A python library for controlling the [iRobot
Create 2](http://www.irobot.com/About-iRobot/STEM/Create-2.aspx). This was used
in ECE 387 Introduction to Robotics class I taught at the US Air Force Academy.
- [video](https://vimeo.com/266619301): robot could only follow the black tap road and couldn't run into anything. If anything got in the way, it had to naviage around it to its final destination
- [video](https://vimeo.com/266619767): robot pet, follow the pink ball

## Install
### pip
The recommended way to install this library is:
```bash
pip install pycreate2
```
### Development
If you wish to develop and submit git-pulls, you can do:
```bash
git clone https://github.com/walchko/pycreate2
cd pycreate2
poetry install
poetry run pytest -v
```
## Use
There are multiple ways to command the Create to move, here are some
examples:
```python
from pycreate2 import Create2
import time
# Create a Create2.
port = "/dev/serial" # where is your serial port?
bot = Create2(port)
# Start the Create 2
bot.start()
# Put the Create2 into 'safe' mode so we can drive it
# This will still provide some protection
bot.safe()
# You are responsible for handling issues, no protection/safety in
# this mode ... becareful
bot.full()
# directly set the motor speeds ... move forward
bot.drive_direct(100, 100)
time.sleep(2)
# turn in place
bot.drive_direct(200,-200) # inputs for motors are +/- 500 max
time.sleep(2)
# Stop the bot
bot.drive_stop()
# query some sensors
sensors = bot.get_sensors() # returns all data
print(sensors.light_bumper_left)
# Close the connection
# bot.close()
```
More examples are found in the [examples
folder](https://github.com/walchko/pycreate2/tree/master/examples).
## Documents
Additional notes and documents are in the [docs
folder](https://github.com/walchko/pycreate2/tree/master/docs/Markdown).
### Modes
The different modes (OFF, PASSIVE, SAFE, and FULL) can be switched
between by calling different commands.
- **OFF:** The robot is off and can charge, it will accept no commands
- **PASSIVE:** The robot is in standbye and can charge. It will send
sensor packets, but will not move
- **SAFE:** The robot will not charge, but you full control over it
with a few exceptions. If the cliff sensors or wheel drop sensors
are triggered, the robot goes back to PASSIVE mode.
- **FULL:** The robot will not charge and you have full control. You
are responsible to handle any response due to cliff, wheel drop or
any other sensors.
### Sensor Data
Sensor data is returned as a `namedtuple` from `collections`. The
information can be accessed as either:
```python
sensors = bot.get_sensors()
sensors.wall == sensors[1] # True
```
