Compound Gearing
You can decrease the speed of your robot and increase the amount of force it
can produce by using gears. There is a video on Compound Gears in the gallery.

Tufts University Center for Engineering Education and Outreach In this activity, we will learn how to create a robot that follows a line on the ground. It will use one light sensor to sense where the line is, and use this to control the motors to steer the car and stay on the line.
Line Following In Chapter 3, we talked about going straight and having a well-tuned robot. I mentioned using the field environment for help in traveling a straight line, such as running along the wall of the field with wall followers. Well, another great way to navigate along the field is to follow any lines that may be present on the field map. For example, the FLL 2009 Smart Move field was a line follower's dream. There were nice thick black lines that could guide a robot to most of the important places on the field. In fact, those lines were placed specifically to encourage teams to incorporate line following, or at least line detection, in their robot's logic. I believe a lot of teams recognize that line following is useful but struggle with how to build and develop a good line-following robot. The code doesn't have to be scary. Yes, you can have some very complicated line-following logic and use lots of fancy algorithms to keep your robot traveling smoothly, but there are simple solutions as well. I will try to explain some of the different techniques available. Remember, though, that these are just examples. I encourage your team to use these as a starting point and build on them; see how much better you can make them.

Use front panel datalogging to record data for use in other VIs and in reports. For example, you can log data from a graph and use that data in another graph in a separate VI. Each time a VI runs, front panel datalogging saves the front panel data to a separate datalog file, which is in the format of delimited text.
