Beschreibung

It's a quadruped robot that using 8x 9G servos with ultrasonic sensor. You may use your own controller board. In this case I am using regular Arduino with expansion shield and a 7.2V lipo battery with 5V UBEC to regulate the voltage down.

Things you need:
9g micro servo x8
1 1/4" M2 or M3 bolts x12
Nylon nuts for bolts x12 (Other nuts works too but Nylon is better)
10"~12" Aluminum tubing (OD5/32 and OD3/16 for each)

Tools I use:
Electronic driller*(Sometimes the hole is too small)
Tube cutter
pliers(for bolt I used)
allen keys(for bolt I used)
File (Smooth out the surface on parts)
AB cold welder (To glue the bolt inside of servo bracket which connect to body as shown in picture. The one with white bracket)

You may want to try this FREDUINO board alone without any servo shields or regulator since it provides 2A output on board. I tried to plug 8 9G servos on it and it works fine with my chassis. Nicely designed!

2014.11.30 UPDATE:
I have expand the main servo brackets(Left and Right) slightly larger(about 1 mm) for some larger servos. you may find them in name: bracket2_L_ext.stl & bracket2_R_ext.stl.
