2. 1. Engineering Design
Central Concepts: Engineering design involves practical problem solving, research, development, and invention/innovation, and requires designing, drawing, building, testing, and redesigning. Students should demonstrate the ability to use the engineering design process to solve a problem or meet a challenge.

3. Standard 1.1
1.1 Identify and explain the steps of the engineering design process: identify the problem, research the problem, develop possible solutions, select the best possible solution(s), construct prototypes and/or models, test and evaluate, communicate the solutions, and redesign.

Step 1
Identify the
problem
We were told to design, build, and
program a robot that could climb the
rope provided then ascend back down
the rope.

5. Step 2 Research the problem the internet sites that were helpful.
Research results
A : We learned from our research that we needed a tight grip on the rope.
B : We learned that most people created a three wheeled robot that worked
very well for them.
C: We learned that the lighter the robot is the less weight it has to pull.

6. Step 3 Develop solutions BRAINSTORM COLLABORATION
Student : Share your ideas with your design team. List your ideas below.
I had the idea to take the tires of the wheels and use two plastic pieces to grip the rope and allow the robot to climb
Nick had the idea of to use one grey piece of a wheel along with a complete wheel to increase the grip and keep the rope from slipping out of the mechanism that allows the robot to climb
We also received ideas from outside sources. They recommended the use of four little wheel and the bare motor in order to keep the mechanism from having to much grip meaning that the rope would get stuck and wouldn’t be able to move because the mechanism is to tight.
Nick and I both agreed that the robot should be lightweight because the lighter the robot the easier it is to drag the robot. Nick and I also agreed that we needed to find a mechanism that would have just the right amount of grip to allow the robot to climb the rope without getting stuck

Possible solution(s)
We decided to try my idea first. The idea of using two bare
wheels to grip the rope. We also kept in mind that the robot
should be lightweight and the mechanism should have grip on
the rope

8. The Somerset Berkley writing rubric will be used for assessment.
Student : Our first robot was quite simple. We first took two wheels and
removed the tires leaving only the grey pieces underneath. We took these two
grey pieces and attached each one to a separate motor. Next we attached
the motors together trying to keep the right distance between the two
gray pieces so that the robot would have just the right amount of grip. The
motors were connected simply using grey bar pieces and the little black and
blue pieces that are used to connect objects. The two grey pieces were
attached to the motor using the long black pieces that have a cross sort of
Shape on the ends. We also used two bars on either side of the grey
pieces in order to keep the rope in between the grey pieces. Lastly since we
wanted our robot to be lightweight we simply attached the motors to the battery
pack using only wires. This way the motors would simply lift the battery pack
and we wouldn’t have to add extra weight by attaching the motors to the
battery pack.

11. Step 6 Test and Evaluate the solution(s)
No our first prototype didn’t work because it couldn’t get a good enough
grip on the rope
2. No our first prototype didn’t perform as expected because it kept slipping
off the rope
3.The program we used was working perfectly fine but we needed to adjust
it so it would have enough grip on the rope.
4. We used only pieces that are included in our kit so our first prototype did
meet the design constraints .
5. Yes the robot was safe and nothing was harmed during this task.

Redesign
We tried many different ways to get our robot to climb the
rope and our final design was very similar to our first design.
One of the differences was that we used tape to keep the two
grey pieces touching so the robot would have grip on the
rope and so the rope would remain in between the two
Pieces. Lastly instead of using bars to hold the pieces
together we used gears
