Problem 4.2.3 Ballistic Design – VEX
Purpose
Have you ever used a sling shot? Have you seen a pumpkin launched from a catapult system or cannon? Using these devices can be fun, but what is the success rate for hitting a target? If the target is large enough, contact becomes simple. However, what if you want to be precise? What if you wish to hit a target at a given distance?
Design challenges provide opportunities to apply skills and knowledge in unique and creative ways. Designers are often asked to come up with solutions to problems.
Designers sometimes work together as a team and must collaborate to create a solution. They must communicate with each other. Every member of the team must contribute if the team is to be successful. Now it is your turn to be part of a design team.
Equipment
VEX building materials
Engineering notebook
Isometric grid paper
Orthographic grid paper
Computer
Procedure
To solve this problem, your team of two to three must innovate to make improvements to a design demonstrated by you instructor. Your team will design a solution to the stated problem. Study the design brief located on the following page. Using the steps in the design process, your team will create a solution to the design problem. Be sure to have your instructor approve any modifications.
Some examples of possible modification are listed below. Ideas are not limited to these, though. Remember also to have your instructor approve any ideas before proceding. Brainstorm some of your own ideas to improve the ballistic device as well.
Make it more accurate/ consistent.
Increase the range.
Incorporate a fuel cell into the design.
Create an automated loader.
Incorporate a joystick.
Have the arm go to specific angles automatically.
Make the entire design mobile.

What are some creative changes that you would make to the design solution if you could start over? 11. Suppose that the client wants your ballistic launcher to be guaranteed to hit a target at least once, given three tries. a. Would a 34% success rate per launch be good enough? Explain why or why not. b. If a launcher hits the target 34% of the time, what is the probability that it will miss three out of three tries? c. Enrichment: If the client defines a “success” as hitting the target at least once, given three shots, what success rate per launch is necessary to succeed 99 times in 100 groups of three shots? Explain your reasoning.
