K-9 Build - Week 7

Every now and again I get a little time to play with K-9, even if its just a little bit at a time.  Over the past week I've made some small alterations to things but last night I decided to start working on the Robotics.  As it is right now I have the motors working and even have the tail wagging all via the remote.  The only thing I'm actually waiting for right now is the chains for the motor to the wheels.  Because I'm using Razor motors I'm expecting them to be pretty damn powerful but also pretty freaking fast, obviously I wont know until the chains get here and I can give K-9 his first REAL test drive.

It'll also be good to know how long the battery will last.  While wiring up the electronics I had to take into account I need easy access to the battery or at least an easy way of charging it, so I used the battery connector from the RC car I previously bought in an attempt to RC K-9 cheaply, I hated it! My battery charger was one I purchased from BGMicro.com I used the wire and connector from the old charger, saving me a few bucks AND making it easy to charge the battery within K-9

I decided I wanted to make a neat pendant for K-9, and so I came up with a design that I was happy with and I think it turned out OK...

 
I was also asked recently about the measurements for the control panel so I just put this together very quickly:

Hope it helps....

Now for the past weeks tinkering photos....

Week 7

you may notice I have the tail Servo connected to the reciever here, however this is not a good idea and Ive noe disconnected it.  Theres a good chance it could damage the Sabertooth so dont do that!

Sabertooth 2x25

Main power cutoff

 The switch is underneath the main base allowing for easier access, only thing I MUST remember is that the breaker is OFF when I charge the battery.

The biggest issue I think I faced was placement.  I changed my mind several times before finally going with this setup...

The Tail... 

  

I attached the servo to the body of K-9 using Velcro this allows me to make adjustments easier, but it holds the servo in place very well...

Ill post a video once I have the chains for the motors and its all working
