Before you program your GoPiGo, you need to decide how your robot’s handler will detect the robot stopping. A seeing eye dog wears a harness with a rigid metal handle that allows the handler to feel the dog’s movement. What will you use to harness your GoPiGo? 

You can experiment with rigid materials (you may already have a yardstick or dowel in your home that would be the right size) or flexible materials (rope, string, or even the leash for a real dog).

You can test your materials by having a friend or family member hold the other end of your harness and lead you slowly around your space while you close your eyes. Have them stop, start, and turn a few different directions during your test. Which material makes it easiest to feel the changes in motion? 

Record your results in a table like this. 

Now that you know what materials work well for a harness, design your own. How long should your harness be? How will you attach it to your GoPiGo? Create a sketch of your harness on a piece of paper.
