Operating Problems
- If the WonderBorg does not beep when the power is turned ON:
Check that the motherboard and motor units are properly connected.
- If nothing happens when the power is switched ON:
If you have previously opened the motor unit to change the gears, check whether
you have done this correctly. Check that the batteries have been inserted,
and that they are the right way.
- If the WonderBorg does not move correctly when you transmit
a program:
Check whether something is blocking the signal between the Interface transmitter
and the WonderBorg’s infrared receiver. Check that the interface and the robots
are far enough apart.
- If the WonderBorg makes a chirping noise while executing a
program, and the stops moving:
Check whether the robot’s leg has been caught somehow. If any of its legs are
interfered with while it is executing a program, the WonderBorg will
chirp repeatedly.
- If the WonderBorg's legs start trembling when the power is
switched ON:
This is not a fault: the WonderBorg is performing its initial operation check.
Just leave it alone for a short while.
- If the WonderBorg goes backward when the program says it should
to forward:
Check whether the motherboard and the motor units have been connected the
wrong way.
- If the WonderBorg does not walk properly:
Check that the legs have been assembled correctly. To make the robot walk
efficiently, the legs have to be assembled at the optimum angle. If you are
using the legs made of plastic-covered wire, check that they are bent correctly.
- If the WonderBorg starts executing the program, and then stops
after a short while:
check the batteries. When the batteries are low, the WonderBorg will sometimes
come to a standstill when executing a movement at the "low speed" setting. If
this is the problem, change the batteries.
- If the Interface is not showing any reaction:
Check that the cable is properly connected. Push it in as far as it will go.
Is the port setting correct?
Consult you PC manual and make sure the port selected is the one to which the
Interface is connected. Is the interface switched ON? Check that the green
indicator lamp is glowing. If the interface is switched ON but the green indicator
lamp is not glowing, check that the batteries are inserted the right way.
It can happen that a scrap of plastic from the battery wrapper has gotten stuck
over a battery contact, so check for this too.
- If an error message appears on your PC screen:
An error message may appear if you select a port other than the one the Interface
is connected to. In this case, the message will disqppear when you click "OK"
on the message dialog window, and you can then select the correct port. In
this case, the cursor will turn in to an hourglass shape, but it will still
work when you click it. Have you select the correct port? Consult your PC
manual and select the port to which the interface is connected.
- If your PC crashes:
Restart your PC.
Have you selected the correct port? Consult you PC manual and select the port
to which the interface is connected.
Troubleshooting Problems with Program Transmission
- If you transmit a program, and then find that the WonderBorg still behaves as it
did before:
The WonderBorg cannot receive a program while the green LED is flashing. Check
that the WonderBorg and the Interface are facing one another, and are close
enough. If they are too far apart, or if there is an object between them, it
will not be possible to transmit the program. The WonderBorg’s infrared receiver
shouldn’t be more than 20cm away from the Interface, and there should be nothing
in the way between the two. Is someone using another WonderBorg close by? If
so, this may make it impossible to transmit programs to your own WonderBorg.
Are you using the robot in an extremely bright location? This can make it
impossible to transmit programs to your WonderBorg.
A. If the program is transmitted successfully: the WonderBorg gives a short beep.
B. If the program is not updated: the WonderBorg gives a long beep
C. If a faulty program has been received: the WonderBorg gives three long beeps.
Problems with Sensors
- If the touch sensors are not reacting properly:
Check whether one of the sensors has come loose from the rubber socket holding
it in place. You will need to remove the body shell. If you are using the
antennae made of plastic-covered wire, check that they are bent correctly.
- If the infrared sensors are not reacting properly:
Go into the Set Up screen and adjust the sensitivity using the "Infrared
sensors" gauge.
- If the Light sensor is not reacting properly:
Adjust the sensitivity using the "Light sensor" gauge on the Set Up screen.
When programming, bear in mind that at certain levels of brightness, the
WonderBorg cannot distinguish between "Light" and "Dark".
- If the floor sensor’ "OFF" reaction is triggered while the WonderBorg is walking:
Check whether the WonderBorg’s body is tilted because it has stepped up on
some obstacle, or because of the way its legs are bent. Marked tilting of
the body can sometimes make the floor sensors lose track of the floor.
If the floor is black (or very dark in color), the floor sensors will be unable
to detect the floor.
(Hint: the speed of the flashing green LED indicates the type of floor surface
(Light / Dark) as sensed by the WonderBorg - In addition, make good use of
the Interrupt function)
- If the floor sensors are not reacting properly:
The performance of the floor sensors may vary slightly from one WonderBorg
to another. Go into the Set Up screen and adjust the sensitivity, using the
"infrared sensors" gauge. When programming, it should also be kept in mind
that at certain "Floor status" settings, the robot may be unable to distinguish
between "Floor sensor ON" and "Floor sensor OFF".
- If the infrared sensors and the floor sensors are not working:
If you are using the WonderBorg in a very light or brightly-lit location, the
obstacle sensors and floor sensors may not react.
- If the infrared sensors and the floor sensors have become less effective:
Check the batteries: when the batteries run down, the sensors effective range
shrinks. If this is the problem, change the batteries.
- If the WonderBorg will no longer move forward (or carry out some other action in
question) even though none of the sensors is reacting:
Are the blocks "Nothing Here" and "Advance" (or the other action in question)
waiting for a condition specified in a line higher up the panel? If sensor
are reacting less effectively than before:
Check whether you have set the number of steps in the command block to more
than 2. While the WonderBorg is executing a command block, it cannot react
to any other sensor block, so care is needed when the number of spaces in
the command block is set to a number higher than 2 (i.e. when a single command
block takes some time to execute). If you want a sensor with a higher priority
to be able to take effect during the execution of a block involving more than
2 steps, you will need to specify the command block in question as "Interrupt".
Again, if you want to speed up the reaction of the sensor even when the command
block does not contain more than 2 steps, you should specify the command block
as "Interrupt".
