Step-by-step instructions to build a Sciborg

1. Put the motors on facing forward

2. Add some structure and the worm drives. Notice thate one edge of the "worm" is rounded and one is flat. Make sure to put the flat agains the supporting LEGO block.

3. Add your wheels with an attached gear.

4. Connect the "worm" to your wheel using a couple more gears. Also note that we're adding some connectors for structural integrity!

5. Now, we're going to build the rear wheel. Here are the parts you'll need:

6. Put the wheel together

7. and connect it to the LEGO pieces.

8. Put the wheel on and put in your braces. You may want to add other braces while you're at it around the rear wheel to give it more support.

9. Now, let's build a bumper.

10. This will allow our sciborg to "sense" bumps more easily.

11. Attach the bump sensor and then the bumper.

12. Connect everything up and we're done!
