parts needed include:
an NPN transistor
a resistor (the value of which later be determined later)
batteries (between 6 to 12 volts depending on size of robot and motor requirements, I used two 3v button cells).
two motor and gearbox assemblies
a light dependent resistor (LDR)
and a suitable shell. (mine was the clear case from a toy, it measures 45mm in diameter).
a multimeter or ammeter
note: the picture does not include the transistor because at the time of taking the picture i was still in the process of designing and didnt think that the transistor was neccesary. also, only one resistor was needed.

You can eventually print an insect head / smile / other to put in front of the hexapod, to personalize it.
You need also the ELECTRONIC PARTS:
1x Arduino Mini or Arduino UNO (or compatible)
3x Microservo 9G
4x AA batteries (better if rechargable)
Then, if you want to make a light follower robot, you need:
2x 10K resistor
If you want to drive you robot using a nunchuk, you need:
1x nunchuk adapter (you can buy it or you can remove from an old / broken wiimote)
1x 10K resistor
If you want to drive you robot via bluetooth, you need:
1x HC-05 (or compatible) bluetooth module
1x 2K2 resistor
1x TS2950 33 (or compatible) voltage regulator
