3.  With Plan Sheet, either as one sheet or two sheets, lay out or draw the vertical column for your robot. Start gathering information to construct the robot vertical column you want. You can also draw the part on regular drawing paper. Copyright © Texas Education Agency, 2012. All rights reserved. 3

4. 1. Draw one or as many drawings as needed. 2. Refine or select the part that is best for the robot. 3. The material might have a reaction on the robot, so a redraw may be in order. 4. Keep in mind all the features that are needed (construction strength, speed, function, purpose, weight). 5. Choose the best one, not necessarily the best drawing. 6. Choose the best person and the right tool to make the part. Copyright © Texas Education Agency, 2012. All rights reserved. 4
