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.

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.

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.

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 ]
