 ## Required Hardware
 
-* 1x Raspberry Pi
-* 1x Camera Module for the Raspberry Pi
-* 1x Arduino UNO
-* 1x USB A-to-B (short)
-* 1x Micro USB (short)
-* 1x Motor Shield
-* 1x Photo resistor
-* 1x USB Power Bank
-* 1x LiPo Battery
-* 1x Chassis with DC Motors and wheels
-* 1x Servo Motor
-* 1x UltraSonic Range Finder
-* 1x LED
-* 2x 10k Resistor
-* 7x wire
+* Raspberry Pi with the Camera Module
+* USB Power Bank: Choose carefully! It should provide a 5V 2A or at least 1.5A usb out to power up the Raspberry Pi.
+The Raspberry Pi needs a lot of current for the camera module, wifi, and arduino is also powered by the Raspberry Pi
+that's why choose a powerbank with at least 5000mAh! Ideally it has some status led so we can read the battery life with a photo resistor.
+* Photo resistor + 10k Resistor: To read the battery life of your powerbank
+* micro usb cable 0.6ft: To connect the powerbank with Rapsberry Pi
+* usb A-to-B cable 0.6ft: To connect the Raspberry Pi with the Arduino
+* Arduino Uno or Mega
+* Motor Shield (for example: Adafruit: http://www.adafruit.com/products/81)
+* LiPo Battery (for example: Hacker LiPo Akku 11.1 V / 1800 mAh (30 C))
+* Chassis with DC Motors and wheels: just google "robot chassis 4wd"
+* Servo Motor: for a 180° view
+* UltraSonic Range Finder: to measure distance
+* one LED: to use it as a status led
+* some wire
