This project has evolved some , the basic rundown is I'm modding two Omnibots , one a regular the other a larger 2000 model. I will have two ezb kits , rad base idea was thrown out because of so much noise but could go back on the table if the omnibot drivetrain is too weak to pull it.

you need a mount like Helicopter .LOL 3 servos,(L to R, F to B, Spin) I'm sure you can do it .
@ww321r. That sounds like a option minus the head spinning. Maybe like a ball joint with pushrods going down to neck where the three servos will be ! If anyone finds a specific piece of hardware please link me ! Thankyou
Spin meant ,left /right movement. You could make a gimbal I'm sure. It would allow you to tilt the head at any angle . Like this You would attach the servos at 90% from each other centered on the pivot point. Should make it very lifelike

gimbal
Or like this idea

Here is my proposed rangefinder placing. The front is radar , sides are still on the drawing board but the idea is that the could measure a couple inches off the wall to make sure Omnibot is not scraping when vacuuming. Rear is ONLY used when backing up for object avoidance. I was thinking of one sensor faced down on the front edge to avoid drop offs and stairs. I have thought of a sensor for edge avoidance on the back too. I have 3 sensors on the way and one was included in the kit. Any better ideas?? Feedback?
Ok I used a new 40mm x 40mm x20mm fan and VGA heatsink to add some additional cooling. The fan has a few drops of super glue attaching it to the heatsink. The heatsink has arctic silver paste on it where the voltage regulators touch it. At the bottom where it meets the board its just 3m double sided tape. I did cover the outside edge of the blade fuse with electrical tape to prevent any paste run from touching anything other than the heatsinks.
Update: card reader / blue led fan controller came in! Also the LCD voltage,amp, watts and temp meter for power supply monitoring . Plus the fans and Blueray player came in !!! Lastly the voltage step down power supplies came in so I can power ezb from 12v battery , the motors at 6v and seperate power supply for High Torque servos as well
Wow
All I'm waiting on now is my h bridge motor controller from dj which is in the mail.
Now I just got to figure out where I'm going to mount these things. I can do cutting on chest and cut edges of controller off and put it in the chest......OR I noticed the drawer in the back of omnibot 2000 is the same width as a standard cd drive bay. This is crazy that I was thinking of putting everything in the chest and this is perfect size. Downside obviously is putting drives in the back is less accessible. Any suggestions guys??
That's some serious fan!! I think this bot combo is gonna be aweeeeeesome
Lol yea but moves 6 cu ft per minute and is very quiet. Low current draw for the airflow too , given the presence of other things generating heat , like CPU , power supply , and other stuff I want to make sure this little guy has excellent cooling.
