Ozobot Activity
RCNET Nuclear Robotics Module Hands-On Activity
Do these devices meet the strict definition of a robot? Why or why not?
Can you identify the inputs, outputs, or even guess the logic control mechanism?
Would robots similar to this be suitable for use around radiation? How about stairs, or debris covered floors?
If this robot had a fixed gripper for moving objects, how many degrees of freedom could it be said to have?

Form
(Open Discussion)
Take a look at your Ozobot.
What observations can you make about its form?
What protections does this form provide the Ozobot?

3. RCNET Nuclear Robotics - Hands-On Activity
Form
The Ozobot has a rigid plastic shell.
This form offers little protection from heat, moisture, solvents, or radiation.
The polycarbonate plastic offers a fairly tough yet transparent shell through which to see the internals.

Outputs
Can you identify some of the Ozobot’s outputs?
(Answers revealed on next slide)

7. RCNET Nuclear Robotics - Hands-On Activity
Outputs
The twin micro-motors are the primary outputs on the Ozobot.
There are power and status LEDs on the top of the Ozobot that should be considered outputs as well.

Logic
From a simple examination, can you identify anything about the logic of the Ozobot?
(Answers revealed on next slide)

9. RCNET Nuclear Robotics - Hands-On Activity
Logic
There is not a whole lot of information that can be gleaned from appearance alone.
(Students familiar with microcontrollers might identify the specific brand and type of microcontroller used, or may point out that it is a type of software logic. )

Navigation
(Remove the printed tracks from the Ozobot package and lay them flat on the table. Briefly press the button on the side of the Ozobot to turn it on, and place it anywhere on the track. Observe its behavior. Note that some color patterns trigger specific actions according to the default Ozobot program.)
(Open Discussion)
Would you consider the Ozobot navigation a closed loop control?
See the quick start guide for a list of the color codes that Ozobot interprets by default, and the associated actions it performs. The Ozobot website hosts a number of printable brain teasers and games for use with the Ozobot as well.
If Ozobots are unavailable, a video demonstration can be viewed at the following URL.

Programming
Ozobot may additionally be reprogrammed using any browser with an internet connection, and an intuitive drag and drop programming tool called Blockly that’s hosted on the Ozobot website.
There is also a app for mobile devices called OzoBlockly that may be used to program an Ozobot.
The Ozobot has a special programming mode that uses the color sensor to receive instructions from a computer screen. The Blockly programmer will quickly flash a series of colors on the screen that the Ozobot color sensor can interpret as new instructions.
