Beta Bots

 

The Beta Bot series of Rampage Robots will incorporate three levels in the base module alone.
The first level (early rendition pictured) will contain a dual-processor motor control system and a standalone system monitoring processor. Full documentation will be placed in the Research and Hardware sections as each part becomes available.

Build a Pan-Tilt Camera Mount in Less Than an Hour

Submitted by rampagerobotics on Sun, 05/24/2009 - 14:54

 

We recently received two new color CMOS cameras from Electronics123. Immediately, we wanted to mount one onto a Rampage Robot.  Fast prototyping with small scale PCBs allows for rapid development of structural elements of a pan-tilt camera.  Since parts were gathered while constructing, I used what I had laying around.  After devising several methods for pan-tilt we came up with the following solution. 

Isometric View of Robot with New Pan-Tilt Camera

Sparkfun:
2 x PRT-08808 - ProtoBoard - Square 1" Single Sided (Comes in a package of 2)
1 x PRT-08810 - ProtoBoard - Round 2" (To be cut in half)
1 x PRT-00553 - Break Away Headers - Right Angle
(We didn't have these on hand but bent straight pin worked fine)
2 x ROB-09065 - Servo - Small
(These are not the ones we used but are the same size)
5 x PRT-08993 - Screw 2-56 Button Head - 3/8"
4 x PRT-08995 - Machine Screw Nut 2-56

Electronics123:
1 x BB016 - C-Cam8-6016IR Miniature CMOS Camera

Miscellaneous:
8 - Servo Horn Screws (I used left over screws from the inside of a Game Boy.)
4 - 2-56 Washers (If screw head is too small for servo.)
Build time with the help of a dremel and soldering iron is less than 2 hours.
Please view the pictures below as a guide for building your own.

We plan to build a stereo camera mount next.
Official PCBs will be manufactured for this type of pan-tilt camera mount.
