If the robot frequently resets then you may have a bad battery or battery connection. Check your
batteries have a good charge and are making a good connection with the battery holder terminals. Are
the battery terminal screws tight? Some cheap batteries may not be able to deliver enough current.
If the head does not follow at all then check your eye has power (5V) and that the orange wire is
connected to D8. Double check everything in steps 14 and 18.
If the head works but the legs don't move then your diode that replaced the servo power jumper in step
19 may be around the wrong way or not plugged into the correct pins. Check step 20 to make sure you
have the servos plugged in correctly with the signal wire closest to the female header.
If the robot walks funny then you may have accidently swapped hip and knee servos. The hip servo
allows the leg to move forward and backward. The knee servo allows the leg to move up and down.
If the robot cannot stand on it's hind legs then check you have the correct version of the code. NiMh
batteries are heavier than LiPo batteries. This affects the robots ballance. You may need to play with the
code or adjust the position of your batteries a bit.
If you are Using NiMh then you will probably need to remove the voltage drop diode and re-install the
voltage selection jumper for the servo power. This will run your servos at 6.6V giving them more
power but there is a greater chance of the servo stripping a gear or overheating.
Step 26. Give your puppy some personality!
The Sample code is just the beginning. Experiment with it! If you make a mess of it you can always
download the original code and start again.
Moods such as happy and bored are easily programmed into the robot. Use a counter to determine
happiness by how much a person plays with it. When they stop playing then the counter counts down.
Boredom sets in when you don't play with it for a short while. Perhaps your robot will be naughty if it
becomes too bored?
