Typically, you learn how to wobble before you learn how to walk. But in the world of bots, anything is possible! That is why a day after showing you how to walk and two after showing you how I roll, I am back to show you how to do a little wobble wobble. That's right! In almost no time, you can be out wobbling around with the best of 'em. All of the parts in this project are simple to find and even less-than-experienced bot builders should be able to make this one pretty easily. And, more experienced bot builders should be able to have some fun modding this one, as the casing leaves a lot of room for experimentation.

Step 1: Go Get Stuff
You will need:
(x2) continuous rotation servo motors with the controller removed**
(x2) self-adhesive oval coat hooks
(x1) small plastic container
(x4) zip ties
(x1) 4 x AA battery holder
(x4) AA batteries

Step 2: Remove the Horns
(The servo horns are the gear-like objects attached to the motor shafts.)
Step 3: Insert
Step 4: Mark
Step 5: Drill
For the smaller mounting holes, an 1/8" drill bit should be suitable. For the motor shaft, I recommend using either a 3/8" or 1/2" drill bit.
Step 6: Mount the Motors
Step 7: Wire It Up
Next, twist together the remaining three wires to form another pair.
You can solder them for a more permanent bond, if you wish.
Step 8: Close It Up
Close the case and reattach the servo horns.
Step 9: Wheels
You should now be left with self-adhesive oval wheels.
Step 10: Attach Wheels
Step 11: Power It Up
Experiment with putting the bot on different sides to observe all of the ways it moves.
