Since my original work on BOB (Bret's OmniBot) I have worked on a couple of other robots and now Bob is feeling left out. So it is time for an upgrade. Soon he will become Gunslinger Bob and sport some killer weaponry. Thanks Josh!

Ezang's My New Robot - Spider Bot
If you missed my new robot, here it is again, enjoy and laugh:
I made a plate out of ABS and secured it with 4 screws. It works perfectly and is easy to assemble and disassemble if needed.
Then I mounted the motor controller under neath the grill that sits on top of the transmission. It sits perfectly in the space there near the motors and has plenty of ventilation from all of the grills over the tranny.
Mounted my antenna cable to the bluetooth antenna to extend the range.
and on the back side of where the EZ-B is mounted is my Buck Transformer to give me 6V for servos and guns, and below that is my 3.3V transformer for the laser sight.
Now I have to wire up my switch, charger jack, battery, etc.
yay
Spent last night designing my wiring scheme and today I will start with all of the wiring. Getting closer....
Mounted my power distribution block.
I sent power to the ESC for the motors and routed this thru a switch so I can shut power to the motors if I need to. There is also a main power switch for the electronics.
got my power lined out for the EZ-B, 6V for servos and guns, and 3.3V for laser. I also got the TIP 120 for the laser wired up. Still need to make some for the guns and the lights in the head.
Be sure to ground the shielding of your coax cable or the Bluetooth RF signal won't make it up to the antenna. Have you tried it out. The antenna help any?
I receive the 2.4ghz WiFi adapter yesterday for direct replacement . I believe I will wait till I get the Class 1 ( that's 300ft range vs class 2 30ft) Bluetooth 2.4ghz to make a direct comparison. If the class one Bluetooth remotely has similar integrity it will be the way to go for ad hoc direct connections without the need of a WiFi router.
For sure let me know if the external antenna made range / signal integrity improvements. You should be able to compare by testing it without the antenna plugged in and with it plugged in.
