  2. Introduction to Pro-Bot Programming • What is a Probot? • Care of Probot • Pens • Basic commands • Repeat commands • Sub Programs – procedures, sensors, pause command, move on a signal eg hand clap • Procedures Proc 1-32 Pro-Bots Kate Lesterand Nancy Chaffer PCS TPL 2010

  3. The Pro-Bot is the 'big brother' of the Bee-Bot and allows more complex programming involving • Programmable distances; • Degrees of turn; and • Use of sensors. • It includes a simple pen mechanism and a standard connector texta that can be used to draw routes and reflect upon and record progress. • The Pro-Bot • Reinforces concepts across 2D Space sub-strands • Gives students the opportunity to apply positional language and extend everyday vocabulary; and • Encourages small group skills.

  8. Editing your program • Use the scroll keys located next to the menu key to edit your program. • To insert a command in between two commands, move the cursor onto the command you want to insert after, then type the new command. • To delete a command press the Clear key. Pressing Clear will only delete the last key pressed on each line. Pro-Bots Kate Lesterand Nancy Chaffer PCS TPL 2010

  9. Repeating commands • To simplify typing in commands, you can use the Rpt[ key. • To draw a square, you can set the Pro-Bot to draw one side of the square then turn 90º but do this 4 times. • Rpt[ 4 ] • The number you press is how many times the action within the brackets is repeated.

  10. Moving different lengths and angles • To change the distance enter the required cm after the key eg 40 (40cm straight ahead) • To change the angle, press 30 (a 30º turn to the left) • Repeat commands for a triangle: Rpt[ 3 10 120 ] • Repeat commands for a ? Rpt[ 6 10 60 ] • Repeat commands for a circle: Rpt[ 36 1 10 ] Pro-Bots Kate Lesterand Nancy Chaffer PCS TPL 2010
