To program Tuff-Bot directly, use the buttons on the keypad.
The forward and back arrow buttons move Tuff-Bot approximately 20 cm or about 8 inches.
The right and left arrow buttons rotate Tuff-Bot 45 degrees. Pressing these buttons don’t move Tuff-Bot; they just turn it to point in the new direction.
The X button clears Tuff-Bot’s memory, erasing any entered commands.
Tuff-Bot can store 200 commands, which include forward/backward movement, turn commands, and pause.
When you press Go, Tuff-Bot will run all the commands in the sequence, with a short pause between each command. (See more about the pauses in the Speed button section below.)
When Tuff-Bot has finished all the commands, it will play a sound. You can turn the sound off using the Sound switch.
To stop Tuff-Bot while it is moving, press the Go button.
Pressing the Pause button, which has two vertical lines, causes Tuff-Bot to stop for .5 seconds before continuing its program.
The Speed button has settings for three different modes.
- Mode 1: Button is not lit. When first turned on, this setting is active. Tuff-Bot will pause between each step in its program.
- Mode 2: Button shines green. Tuff-Bot will not pause between commands when traveling in a straight line.
- Mode 3: Button flashes green. Tuff-Bot will not pause between commands when traveling in a straight line. Also, turns will be faster for better performance on an uneven surface.
The Light Sensor will automatically turn on the headlights when Tuff-Bot enters a dark environment.
Pressing the Avoidance button turns this feature on and causes the button to shine green. Tuff-Bot will then back up when it sees an obstacle in its path and try an alternate route. During this obstacle avoidance, the front 3 lights will turn red and Tuff-Bot will play a sound. To turn avoidance mode off, press the button again and the button’s green light will turn off.
If Tuff-Bot is not avoiding obstacles, make sure avoidance is activated and its light is green. The obstacle must be high enough to be trigger the sensor. Small objects may not be seen.
