View source for Drive a square using gyroscope (Lego Dance)

== Introduction ==

The dancing area of Robotic dance is large, and thus a reliable method to drive geometrical forms is needed. This exercise is to drive a square. We show two different methods.

== Theory ==

[[File:PolygonExample ManimCE v0.13.1.gif|thumb|Drive 0 degrees, 90 degrees, 180 degrees and finallu 270 degrees.]]

The plan: We use two different methods. 
# Drive using gyroscope but turn using simple steering block without gyro.
# Drive and turn using gyro. This method requires variables, but is still rather easy.

The code: Quite easy, only a few coding blocks is needed.

== Exercises ==

# Turn one more time such that the ending and starting direction is the same.
# Make a larger square.
# Make the robot end at the exact starting position.
# Drive faster or slower.
# Check the meaning of ''c'' variable. Make it smaller or larger.
# Drive a pentagon and hexagon.
# Drive a spiral
# Attach a pen to the robot and use LOGO drawing.
