2. Construct a Robot by a Plan Sheet
Basic Robot
We are going to construct a robot part by part.
The size and speed will be determined by its part.
Later in the instruction, the size and speed will be determined by the controller.
We will learn how to use a Plan Sheet, gather information, select the right part, and construct that part.

First
With Plan Sheet, either as one sheet or two sheets, lay out or draw the body for your robot. Start gathering information to construct the robot body you want. You can also draw the part on regular drawing paper.

Things to Keep in Mind
Draw one or as many drawings as needed.
Refine or select the part that is best for the robot.
The material might have a reaction on the robot, so a redraw may be in order.
Keep in mind all the features that are needed (construction strength, speed, function, purpose, weight).
Choose the best one, not necessarily the best drawing.
Choose the best person and the right tool to make the part.

The Body
The BODY is used to hold wheels, vertical column, arm, motors, and other wires or attachments. The students are going to use boxes as place holders to arrange and design the robot. Add special features to make it easer for the robot to perform its functions, to set its height from the ground, and to balance itself.

7. STORY BOARD (cont’d) CONSTRUCT A SHAPE FOR YOUR ROBOT
List the machines you will need to cut and construct the body.
Use several drawings until you find the
functioning body you like.
Basic considerations - make the shape
to best perform the task you need. Bring
in the object close, and in position to
best perform the task.
