Classwork 1: 10 points


Be A Robot

You should work in groups of at least 4 persons.

The goal of today's activity is to learn about the parts of a robotic system and how they work together. The parts we'll study are:

Today, we will divide into teams of four people who will together as a "robot" build specific objects out of blocks (please do not write on the blocks!).

Each team will consist of:

The Prof/TA for your team will have descriptions of the objects that should be built out of your block. She/he will show the "head" the objects one at a time. Once an object is shown to the head, your team should try to build it as quickly as possible, according to the above job descriptions. After completing an object, switch roles and try to build another object.

NOTE: Your blocks should be the same shape as the picture you see, but may be a different color. Ignore the colors.


Classwork 1 Writeup (10 pts)

Discuss the following with your group and writeup answers. Be sure to list all the names of your group and turn in just one sheet at the end of class.

  1. Questions from the activity.
    1. Which of the four parts was the hardest to play and why? Which was the easiest and why?
    2. What type of block combinations were hardest or easiest to build with your four person robot?

  2. Give a general description of how you would "program" a robot to "walk" into this classroom and find the box of soft blocks. Assume your robot is the height of a person, can see and recognize shapes, and can "walk" forward and backwards and can turn in implements of 45 degrees. Also assume the room is full of tables, chairs and people walking around. The box may be anywhere in the room. What type of information do you need to tell your robot?
