Simple “turtle” type commands?

I want to set up some simple "turtle graphic" type examples for a class, and I was wondering if there some basic commands for turning x number of degrees, then moving forward in the resulting orientation for a given time.

Most of the chassis commands seem to incorporate multiple parameters, such as heading and duration one command. I could use simpler commands for teaching, eg

Number of sides = 3
Repeat for number of sides
    Turn right 360 / number of sides
    Move forward for 1 second

Do you know if this is possible?

Thanks, that seems to work well. I have a Sphero robot with an IMU, and on that one I need to read the existing heading and add the turn angle.

On the Robomaster S1 the turn seems to be relative, which is good.

I notice an odd thing: it pauses for quite a long time after the second turn, I wonder if it is waiting for the IMU to settle down or something.

Here is the equivalent for a Sphero RVR - since it makes its turns using absolute values, I have to read back the existing heading first

Strange... I ran the exact same program and did not experience the pause after the 2nd turn.

It’s pretty consistent. I’ve narrowed it down a bit. It pauses for 2 seconds before starting the final straight segment, after making the last turn.
