Mechanical Build Instructions

It’s possible to build a robot using the components themselves as the frame.

 

Step 1 : Adding Wires To The Motors

This is what the motors look like starting off:

 

We need to attach wires to both of the copper terminals on each motor:

 

You should have 4 long purple wires in your kit. Each purple wire has one end that is stripped longer than the other like so:

 

Bend the long end into a hook like so:

 

Pass the hook through one of the motor terminals:

 

Squeeze the hook closed with your fingers to make sure it can’t fall off the motor terminal like so:

 

Do the same procedure with the other terminal:

 

And then do the same thing for the other motor. Both motors should have two wires connected to them.

 

Step 2: Preparing the Ramp

The ramp is useful for charging other robots, it makes it easier to knock them off the table.

Start off with the breadboard packaging. There is a cardboard backing that looks like this:

 

You need to cut it along the blue line with a pair of scissors so you are left with this:

 

Once you have done that, mark a rectangle in the same location as this photo. Using the grid on the cardboard you should be able to line it up to match the picture:

 

Then use a pencil, scissors or screwdriver to make two holes in the cardboard. You want to join the two holes together to make a rectangular shape like the one we drew in the last step:

 

Now we need to bend that cardboard at a 45 degree angle. Use a table or something similar as shown in the picture below. You want to bend at the blue line just to the right of the hole you just made:

 

After you are finished bending it should look something like this:

 

OK so that is the ramp made. Now just plug the IR sensor into the hole you just made like this:

OK so now that we have the IR sensor attached to the ramp, it’s time to stick the ramp to the battery pack.

 

Step 3 : Putting Sticky Pads on the Battery Pack

  • Make sure your on/off switch is in the same place as the picture!

Place sticky pads down on the battery pack as seen below. Make sure to leave a bit of a gap between the edge of the sticky pad and the edge of the battery pack.

 

 

Stick down the ramp like so, the underside of the IR sensor should stick out past the edge of the battery pack:

Once that is done, its time to prepare the motors and wheels. There is a bit of a trick to this so look at these pictures carefully.

 

Step 4: Adding the Motors and Wheels

When you put the wheel on the motor it slides all the way in like so:

This is not what we want because the wheel is too close to the motor. You can gently pull the wheel away from the motor a little bit so you have a gap as seen in this photo:

Once you have that done for both motors we are ready to stick them to the battery pack. Try to line up the motors as straight as possible. The more straight you stick them down, the straighter your robot will drive!

When you stuck down the sticky pads you left a bit of space to the edge of the battery pack. Do the same with the motors. The edges of the battery pack are rounded so if you stick the motor to the very edge it won’t stay there for very long so stick the motors down a bit in from the very edge of the pack as seen in this photo:

 

Stick down both motors so that you end up with something like this:

 

Step 5: Adding The Breadboard

Once you have that done, its time to stick down the breadboard on top of the motors. Try to line up the breadboard in roughly the same position as shown below:

 

 

Step 6: Adding The Ultrasonic Sensor

Once that is done the last step is to add the ultrasonic sensor. First you need to stick two sticky pads on the end of the breadboard as shown below:

 

Once that is done you can stick the ultrasonic sensor on like so:

That is the mechanical assembly finished! Now let’s get it moving around.
