I-Sobot

This is front cover for japanese I-Sobot robot upgraded to BT version.
To control I-Sobot using any phone over Bluetooth you just need: arduino nano + HC05 + IR transmitter from any useless remote + NPN transistor +1K resistor

Schematic :
nano's digital pins 3,4 to RX/TX of the HC-05 BT module, 5 to IR Transmitter diode from any useless TV remote, BT546 NPN transistor and 1K resistor is connected to power up Arduino and BT module streight from Li-Ion power supply. I have used old SAMSUNG Li-Ion battery + Charging&protection board.

For programming you will need library posted in arduino.cc forum (1st pageout off 4).
Below is my Arduino sketch:
