Using BitBot PRO to draw polygons: Part 4 Now we can generalise by creating a function that takes two values: number of sides and length of each side. This example draws an octagon by specifying 8 sides to the function:

Draws an octagon by calling a generalised function for drawing polygons

Using BitBot PRO to draw polygons: Part 3 we can then generalise the square to any number of sides by changing the number of repeats to the number of sides required, and the angle to turn to be 360 divided by the number of sides. This is valid for all numbers greater than 2. A hexagon has 6 sides:

Draw a hexagon by repeating 6 times, and turning 360/6 degrees each time.

Using BitBot PRO to draw polygons: Part 2 To complete the square we need to repeat this operation 4 times, once for each side (or once for each corner). So let's use the Repeat loop built in to Makecode. This code will draw the full square and leave the BitBot PRO where it started:

Draw a square by repeating four times the operation of drawing a line and turning 90 degrees

Using BitBot PRO to draw polygons: Part 1 Because BitBot PRO can move and turn accurately, we can use it to draw geometric figures. Let's start with drawing a square. We first have to draw one side, then turn 90 degrees. Like this

Draw a line then turn 90 degrees. This is 1/4 of a square

Pleased that us astronomers are considered human by at least some of the population 😉

Our latest robot is BitBot PRO, an intelligent version of the BitBot XL. Its "Smart Motors" make accurate movements trivial, enabling easy drawing of regular polygons and even arcs. School children need this, now! shop.4tronix.co.uk/products/bit...

BitBot PRO with "Smart Motors", multiple analog line following sensors, 12 RGB FireLeds, 2 light sensors, on board sounder, pen holder and accessory connector for many different options. Includes a built-in IR receiver and IR keypad, so you don't use up the accessory connector and can still attach an ultrasonic sensor, LED matrix or OLED optional accessories.
