Troubleshooting
Edison robots are designed to be easy to use straight out of the box but powerful
enough to grow with students on their robotics and coding journeys. Like any
computing device, issues can occasionally arise with Edison.
Where to start
If you do encounter an issue, a
lways start by checking Edison’s batteries.
Remember, low or flat batteries can cause a range of issues with Edison.
Next, make sure the programming device you are using is properly set up as detailed
in this guide. Also, check
that your device’s volume is turned all the way up.
Low or flat batteries and programming devices not properly set up are the most
common causes behind problems using Edison.
Line tracking
If you are having trouble with a line tracking program, check the following common
issues:
•
Only use non-glossy paper and, if laminating the paper, only use a matte-
finish laminate.
•
Edison will be best able to follow a line if that line is a very dark colour (such
as black), approximately 1.5cm (0.6 inches) wide and located on a white
background.
•
Always start the robot on the white background, never on the line itself.
•
Avoid running line tracking programs in very bright light, such as sunlight, as
this can negatively affect the program.
•
All of the Edison programming languages except for EdBlocks and the
barcodes require the line tracking sensor to be turned on to work. Double
check your program to ensure you have the line tracking sensor turned on.
Obstacle detection
If you are having trouble with an obstacle detection program, check the following
common issues:
•
Ensure that your Edison robot’s obstacle detection is properly calibrated using
the barcode and instructions available in EdBook 1.
•
Edison will be best able to detect obstacles which are opaque but not too dark
(e.g. not black) and at least as tall as Edison.
•
Avoid running obstacle detection programs in very bright light, such as
sunlight, as this can negatively affect the program.
