1.5 Finishing Up (Part 1)

Submitted by Canabots on January 24, 2009 - 11:07pm.

Ok, So now we have 2 main parts of the robot (three, depending on whether you've bought your camera or not). Now you need to put them all together.

We will start with the connections between the motors and the Receiver. If you are using Molex housings on both the motors and the receiver, then cut 2 pieces of the .001" pin header off of the strip you received. Each piece must contain 4 pin-headers.Place those headers back-to-back so the smaller ends on both headers are touching and solder them together. Plug the motors into one end of the header row and plug the transmitter into the the other end.

If you are not using Molex housings on the motors, then just insert the striped ends of the wires into the molex connectors on the receiver.

Motor/Receiver Connection

 

 

Put you batteries on the robot. I find a little tape (esspecially hockey tape) works well to hold it in place. Snap in that 3V battery connector and place the robot on the floor. Turn on your transmitter. Now you're going to need to test and determine which motor is controlled by which joystick, since each joystick controls one H-Bridge motor driver on the Receiver. After that, play around with your little robot as long as you want.

 

But we're forgetting something: your wireless camera.

 

To set up you camera, follow the instructions included with it. Then mount it on the front of your robot using hot glue, double sided tape, or even scews if they're included. Mine required a nine volt battery, so I placed it next to the three volt battery pack.

Batteries, Side by Side

Once the camera is set up, I like to give my robos a cleaner, more contained look. You could use twist ties, tie wraps, but I prefer elastic bands. For the receiver, I also used a small piece of tape to hold it in place as the elastic is wrapped around.

Elastic creates a strong hold on parts and give robot a cleaner look.

 

Completed Robot (Part 1 and 2)

Your Micro RC Surveillance robot has been completely built! You may now survey anywhere you like within the respective range of the receiver, and you'll be able to view it from the comfort of your TV or even your computer!

 

In Part 2 of this tutorial, I will show you how to boost the range of your transmitter, aswell as how you can control the robot with your own computer.

Here os a quick demo of the Manual RC control on this robot.

how is the video camera quality?

Got video of the video coming from the wireless camera? I'm curious of the quality and range. I don't trust the claims on those 'use the camera to spy on people' retailer websites . . .

Video Range

According to the site which sells the camera I used, the range is up to 150m without interference of obstacles.

I'm not so sure about that, but I do know that the range is good enough to go through 2 stories of a house, and able to display a pretty nice video feed with sound (actually, the microphone is pretty strong).

The frequency for this camera is 2.4 GHz.
