ozobot-evo 0.2.0

Ozobot EVO library

ozobot-evo

Interface for controlling Ozobot Evo. See the monorepo for more details.

Work in progress, only a web runtime driver for Ozobot Editor available

Usage

import asyncio
import random
from ozobot.evo import EvoHandle, Evo
from ozobot.linefollower import NamedColor, LEDMask, Direction


async def monitor(it):
  async for data in it:
    print(f"Sample taken: {data.value}")


async def main():
  async with EvoHandle(id="ABCDE*") as evo:
    await evo.move(100, 50)
    await evo.rotate(180, 90)

    velo_task = asyncio.create_task(evo.set_velocity(50, 0))
    await asyncio.sleep(2)
    velo_task.cancel()

    await evo.set_led(LEDMask.FRONT_CENTER | LEDMask.FRONT_LEFT | LEDMask.FRONT_RIGHT, NamedColor.BLUE)
    await evo.set_led(LEDMask.FRONT_LEFT_CENTER | LEDMask.FRONT_RIGHT_CENTER, NamedColor.RED)

    await evo.play_sound("happy")
    await evo.play_tone("A", 4, 1, 1)

    await evo.follow_line(Direction.STRAIGHT)
    intersection = await evo.data.intersection.read()
    print(f"At intersection: {intersection.value}")

    async with evo.data.intersection.watch() as intersections, evo.data.color_code.watch() as codes:
      t1 = asyncio.create_task(_monitor(intersections))
      t2 = asyncio.create_task(_monitor(codes))

      await evo.follow_line(random.choice(list(intersection.value)))

      t1.cancel()
      t2.cancel()


asyncio.run(main())
