First Steps

Get familiar with your new robot project!

Steps:

  1. Review guidelines for robot care and safety.
  2. Attach the wheels and tracks.
  3. Learn the buttons and modes.

1.  Robot Care and Safety Guidelines

a) Don’t destroy your bot!  Avoid these things:

  • Leaving your robot turned on and unattended. 
  • Zapping your robot with static electricity. 
  • Giving your robot a bath. 
  • Charging your robot while unattended.

b) Turning on/off and charging:

Lithium-ion cells and safety:  Your robot is powered by a single high-quality lithium-ion cell.  The charging circuit on your robot is designed to prevent dangerous charging scenarios, but it is still best practice to charge it while you are nearby.  (This is true for all lithium-powered devices, but single-cell devices like your robot and cell phones are generally safer than devices with multiple cells such as laptops.)

2.  Attach the Wheels and Tracks

We think you can figure this one out on your own.  Note how the front wheels are already attached as an example.  Attach the back wheels with the short screws.  Tighten gently.  Now you can add the o-ring treads and you’re ready to roll!

3.  Learn the Buttons and Modes

a) Buttons:

  •  Click: On/Off (Disconnects Battery)
  • A: Disable/Enable Motors
  • D: Change Mode (Modes: 0, 1, 2, 3)

b) Beginner Robot Modes:

  • Startup: When the robot is first powered on it goes through a startup routine.  The blue LED will flash 7 times and then the green LED will flash 7 times.  The robot will then enter Mode 0.
  • Mode 0: (7 quick pulses) This mode detects objects in front of the robots “eyes” (ultrasonic distance sensors) and will blink the blue LED faster or slower based on distance to a detected object.
  • Mode 1: (1 Flash) This mode just drives forward at a medium speed.  Watch the robot crash into things.  How could that be avoided?
  • Mode 2: (2 Flashes) This mode uses the Ultrasonic Distance Sensor to detect when the robot is about to crash.  Then it randomly selects 1 of 4 possible actions to stop, back up, and turn to a new direction.  Cool, right?  What else could you program the robot to do with the distance sensor?
  • Mode 3: (3 Flashes)  We call this mode “Curious Scaredy-cat.”  The robot waits until it detects an object and then it will approach with caution.  Then, when it gets close, it will “run away.”
