Robot climb up and down stairs

This is my first robot for climbing stairs. The design is based on Packbot. Finally, I hope I can complete a robot like the Packbot.

For building the tank's tracks. I used the tracks from  'Heng Long  M26'

As the friction of the traks is not enough to hold the robot, I drill holes ( each 2mm) on the tracks. Cut  carpet(backward side)  into many segments, cut CAT5 LAN cable into segments, mount the segments on the tracks.
