3. Interface Overview 1 2 3 4 1. Command Pane: Available Instructions
4 directions: ↑↓←→
Sensor(s)
LED, Sound
Better images TBA
2. Instructions list: The composed instruction set
Instructions list will be changed to a graphical flowchart and allow for drag&drop modification
3. Instruction Parameters: The parameters for each instruction
When a instruction is added or clicked, this panel will change its content accordingly
Each parameter will be visualized
4. Debug Pane
Loads default program for debug
Allows to directly edit programatically generated source code 1 2 3 4

4. Error/Warning detection
The workflow is prototyped according to the diagram
Use File menu to perform file operations
Use Build menu to build the instructions and load them to microcontroller
Error/Warnings will be displayed at compile time
Confirmation message will be displayed after successful compilation
Program Workflow
New file
Save file
Load file
Error/Warning detection
Compile

5. Build and Load
The translator is able to convert instructions to C code and integrate the C code to the pre-defined template.

6. FORWARD Usage: FORWARD [Distance], [Time]
Distance: distance to travel in forward direction
in mm.
Time: time to travel in sec
All parameters changes are instantly displayed
in the List of Commands

7. LEDs Usage: LED [LED1&LED byte value],
[Power LED Color], [Power LED Brightness
Setting]
LED1&LED2 byte value:
-0 if both LEDs are off
-2 if LED1 is On
-8 if LED2 is On
-10 if both are On
Power LED Color: Adjust color of Power LED
from red to green. Takes values from 0(Red) to
255(Green)
Power LED Intensity: Adjust brightness of Power
LED. Takes values from 0 to 255
Power LED Color and Brightness are adjustable
via slider changes. LED1 and 2 are turned On/Off
using respective checkboxes.

8. LEFT Usage: LEFT [Angle]
Makes the robot turn left by number of degrees
specified
Angle: turning angle in degrees.
All parameters changes are instantly displayed
in the List of Commands

9. Song TBA
This slide is TBA

10. WinAVR Integration The prototype is able to invoke WinAVR from the GUI
It compiles C code and loads the executable to microcontroller

11. Risks, Problems and Mitigation
Mitigation plan
Poor User Accessibility
(Overly complex and not engaging enough for school children)
- Prototyping
- Collection of User Feedback
Iterative System Revision
Hardware Limitations
(Low Sensor Resolution)
- Scripting Commands
- Sensor Calibration
Poor development toolset
- Request tool from robot vendor
- Building a microcontroller simulator
