Supported syntax

This coding center uses an educational Python subset.

• Variables, arithmetic/comparison/logical operators, strings, lists, tuples
• if/elif/else, while, for ... in ..., break/continue/pass
• def functions, return, recursion
• import airgo_usb.h (recommended), import airgo, import math, import time, from ... import ...
• Built-in functions: print, len, range, int, float, str, bool, abs, min, max, sum, round, pow, sorted, list
• List/string methods: append, pop, insert, remove, sort, reverse, clear, copy, upper, lower, strip, split, join, replace, etc.

Unsupported syntax

The following syntax is not supported in this simulator. Using it will produce a syntax error.

• class, try/except, with, lambda, yield, async/await
• Dictionary/set literals, comprehensions, f-strings, slicing
• Decorators, type annotations, *args/**kwargs, global/nonlocal
• Single-line blocks (if x: print(x)) and for/while else

Drone API

Uses the same serial commands as the real SYUBEA drone controller. power is 20-500 and time_ms is 100-10000. The airgo_usb.h tab contains working code that validates variables → builds the command → sends it, and you can run it directly from the tab.

Function	Description
airgo_usb.connect(port="COM3")	Virtual serial connection (default COM3)
airgo_usb.disconnect()	Disconnect
airgo_usb.start() / airgo_usb.stop()	Motor start / stop
airgo_usb.takeoff() / airgo_usb.land()	Takeoff / land
airgo_usb.forward(power=200, time_ms=1000)	Forward
airgo_usb.back(...), airgo_usb.left(...), airgo_usb.right(...)	Back / left / right movement
airgo_usb.up(power=200, time_ms=1000) / airgo_usb.down(...)	Up / down (uses 60% of power)
airgo_usb.cw(...) / airgo_usb.ccw(...)	Clockwise / counterclockwise rotation
airgo_usb.speed(level)	Speed level 1-3
airgo_usb.battery()	Battery check (simulator 100%)
airgo_usb.funled(), airgo_usb.gyroreset(), airgo_usb.headless(), airgo_usb.mapping_start()	LED / gyro / headless / binding
airgo_usb.emergency()	Emergency stop
airgo_usb.send("forward 200 1000")	Send a serial command directly
airgo_usb.wait(sec), time.sleep(sec)	Wait
airgo_usb.forward_cm(cm, power=200)	Move forward in cm (helper)
airgo_usb.back_cm, left_cm, right_cm, up_cm, down_cm	cm movement helpers
airgo_usb.turn_right(deg, power=200) / airgo_usb.turn_left(...)	Angle turn helpers

Command menu

Press the Commands ▼ button on the drone_program.py line to insert takeoff, land, move, rotate, altitude and setting commands directly into the code. Edit the inserted power/time_ms numbers as needed.

Command prompt

Running shows [SEND] and [RECV] logs. These reproduce the real controller serial commands, but the web version does not connect to a physical port. A virtual drone is prepared automatically; calling airgo.connect() shows the connection log.

Save / open

Code is auto-saved in the browser. Save downloads drone_program.py; Open loads a local .py file.

Real drone control

This page is a web 3D simulation. For real drone control, use the Resources SYUBEA Drone Controller (v1.01).
