Final Design Project: Space Jam 2021
A. Overview and Theme
The goal of this project is to use a structured design process to design, construct, build and test an
automated system to accomplish two physical tasks. The theme of this competition is basketball.
Your team will seek to accomplish several tasks that are described in the following text and pertain
to the arena depicted in Figure 1.
Figure 1. Layout of arena including top and side views. Red stock item is for the jumpshot task.
Blue stock item is for the passing task. Yellow and green stock items are for the dunk task. Green
stock items are moneyballs.
B. Primary Design Parameters
All tasks will be executed in the competition arena during a 1-minute time period. All machines
must be initially placed on and contained by a starting zone 20”x20” in size and be below an initial
height of 18”. Stock items are located within the starting zone and are plastic spheres 1.57” in
diameter and approximately 0.095 oz. in weight. To one side of the starting zone at a distance of
4’ is the center of target zone 1 (jumpshot), which is a 5 gallon pail with a 13” top diameter and a
14.5” height. To the other side of the starting zone at a distance of 4’ is the center of target zone 2
(dunk), which is an array of 37 plastic containers arranged in a minimum area configuration sitting
on a 0.125” thick board. Each of these plastic containers (nominally 18 oz.) is shaped as a truncated
cone with height of 4.875”, lower diameter of 2.25” and upper diameter of 3.875”. Also on this
side of the arena are 3 field items. One field item (yellow) is located at a distance of 1’ and is
centered on the starting zone. The other two field items (green) are at a variable distance X, where
X is a random variable from 1.5’ to 2.5’. The field items are sitting atop cylindrical bodies made
from standard schedule 40 PVC pipe (0.5” nominal), where the yellow field item is sitting on an
8” tall cylinder and the green field items are sitting on 12” tall cylinders.
Rev. 1 (10 February 2021) 1C. Competition Tasks and Competition Points
Your device will be comprised of various subsystems to accomplish the following tasks. The goal
of the competition is to maximize the points scored for successfully completing these tasks. The
following text describes the tasks and Table 1 summarizes the point values associated with each.
Table 1: Scoring Detail.
Task Competition Point Value
Launch 1 (successful deployment)
3 points/item (hits target zone)
Pass
1 points/item (leaves starting zone)
8 points/item (lands in target zone)
Jumpshot 3 points/item (hit target zone but not in target zone)
1 points/item (leaves starting zone)
6 points/item (green zone)
5 points/ item (yellow zone)
4 points/item (orange zone)
Dunk
3 points/item (red zone)
1 points per item (not in a zone but off of PVC stand)
Money balls count 2x points per zone
1. Launch the System
The system must start, fully at rest, behind the marked starting line in Figure 1. Upon activation
of the track, the system must deploy and complete the competition tasks. Your team will earn
points for successful deployment of the system. Successful deployment is determined by a
successful trigger of your system and abiding by the rules specified at the end of this document.
The following details scoring rules for this task:
• Teams can load stock items labeled in the starting zone in Figure 1 and position system in
starting zone before start
• System must have a perceptible motion from an actuator after button start to score
2. Pass
The goal of this task is to hit the target zone with a stock item. The item is the blue stock item in
Figure 1. Before the start of the round, your team may position the stock item in your system as
needed. Your system must not cross the marked foul line. If it does cross the foul line at any point
of the round, it will receive zero points. The following details scoring rules for this task:
• Crossing foul line (any intersection of line with system) results in no points scored
• Items hitting the target zone will score maximum points
• Items completely leaving the starting zone but not hitting the target zone or resting in it
will score minimal points
3. Jumpshot
The goal of this task is to shoot the stock item into the target zone. The item is the red stock item
in Figure 1. Before the start of the round, your team may position the stock item in your system as
Rev. 1 (10 February 2021) 2needed. Your system must not cross the marked foul line. If it does cross the foul line at any point
of the round, it will receive zero points. The following details scoring rules for this task:
• Crossing foul line (any intersection of line with system) results in no points scored
• Items resting in the target zone container scores maximum points
• Items hitting the target zone but not resting in it will score intermediate points
• Items completely leaving the starting zone but not hitting the target zone or resting in it
will score minimal points
4. Dunk
The goal of this task is to place stock items into the target zone. These items are the yellow and
green stock items in Figure 1. They green stock items are considered moneyballs. Unlike the
jumpshot competition, your system may approach the target zone located on the basketball side of
the arena. The following details scoring rules for this task:
• Money balls must be picked up by system autonomously
• Items resting in a container score points for associated container color
• Items resting on container top lip score points for lower scoring container color
• Items that are removed from the PVC stands will count for minimal points
D. Design Constraints
The design problem is inherently constrained by limits on volume, energy, cost and time. Your
system must be deactivated and static before the start and at the end of the 1 minute round;
failure to do so will result in no points for that round. Deactivated and static is a state of your
machine, defined as a system which neither supplies power to electrical components, nor the ability
to suddenly release potential energy stored in the system via springs, rubber bands, or otherwise
before application of an external electrical input. You are permitted to use energy only from the
electricity supplied from your controllers, 5 mousetraps (Victor Brand, M154 or equivalent), any
mechatronics kit components, 5 #64 rubber bands and gravity. Your team will be provided with a
set of pneumatic and electrical actuators. Your controllers may only power the actuators supplied
to you. The controller also powers the sensors supplied to you. You may also purchase additional
sensors if your budget remains under $100. All sensors purchased must be approved by the Head
TAs in writing and submitted purchasing information will be published on the class website. Please
see the rules at the end of this document for details on the budget specifications.
E. Design Sprints and Machine Performance
You will design and construct devices in 2 design sprints. At the start of each of these design
sprints, your team will prepare and present a fully detailed initial design package that includes the
design and manufacturing plans for a complete system to achieve the target functionality. During
each design sprint, your design may evolve due to revisions that are needed as your team
experientially learns more during fabrication and testing. To accomplish this, your team will utilize
the IDEA Laboratory during: (1) time available in Weeks 8-10 and 11-13 for dedicated studio
hours and (2) open studio hours in Weeks 6-13. To record machine performance, your team will
run your system during open studio or during your dedicated studio timing.
Design Sprint 1: During weeks 8-10 (Mar. 1 – Mar. 19), your system should demonstrate design
feasibility and control system design to achieve the minimum functionalities associated with:
Rev. 1 (10 February 2021) 3• Launch: launching the system (1 point)
• Pass: hitting target zone 1 with a pass (2 points)
• Jumpshot: hitting target zone 1 with a stock item (3 points)
• Dunk: placing 1 regular stock item in a red container (3 points)
A TA will be available for formally recording performance. The score for the above minimum
functionalities is 9 points/trial, your system may score higher than this total as all tasks are in play.
You will run 3 consecutive trials and the average number of points scored will determine your
grade. The maximum grade for machine performance in this design sprint is out of 9 points. Total
scores greater than or equal to this will all be considered a perfect score.
Design Sprint 2: During weeks 11-13 (Mar. 22 – Apr. 16), your system should demonstrate design
feasibility and control system design to achieve the minimum functionality associated with:
• Launch: launching the system (1 point)
• Pass: hitting target zone 1 with a pass (2 points)
• Jumpshot: landing a stock item in target zone 1 (8 points)
• Dunk: placing 1 regular stock item in an orange container (4 points)
• Dunk: placing 1 moneyball stock item in a red container (6 points)
A TA will be available for formally recording performance. The score for the above minimum
functionalities is 21 points/trial, your system may score higher than this total as all tasks are in
play. You will run 3 consecutive trials and the average number of points scored will determine
your grade. The maximum grade for machine performance in this design sprint is out of 21 points.
Total scores greater than or equal to this will all be considered a perfect score.
Final Machine Performance: Final machine performance will tentatively be assessed in the Final
Competition Event below and will be based following the same rules as in Design Sprint 2.
F. Virtual Design Review Event
The design review grade is 5% of your overall grade. It will occur 430-830PM on Friday April 16,
2021. All team members must participate. This will operate in a typical poster session type mode
on a virtual platform. Judges will evaluate your team on the basis of three categories: (1) design
ingenuity/innovation, (2) fabrication methods, (3) technical communication and presentation. The
judges will rank your team in these categories. Each judge’s ratings will be normalized based on
their assessment of a common design review example. Your grade will be based on the judges’
cumulative ratings. A copy of the scoring sheet template will be available on the ME2110 website
for review prior to the event. You will be able to share videos and other materials on the online
platform with the judges and attendees. You will be required to upload a video of an example
design review presentation prior to the design review event.
G. Limited Final Competition Event
A final competition event is planned immediately after the design review event at approximately
6PM on Friday April 16, 2021 and will take place in the MRDC building on campus. Details
regarding the limited final competition event are to follow. Teams will compete head-to-head
following the same tasks as described above. It is expected that a limited number of participants
Rev. 1 (10 February 2021) 4will come on campus for the event, with the remainder joining virtually. The same scoring rules
for Sprint 2 will hold as above. Each team will compete in at least 3 trials. Any tiebreaks will be
determined by key design variables including, but not limited to, overall system cost and overall
system weight.
H. Reports and Presentations
There will be reports/presentations associated with this project, in addition to the design review
described in the above section. The deadlines for these items are given in Table 2. Information
regarding content/formatting of each is provided on the ME2110 website. Unless otherwise
specified by the studio professor, reports and presentations are due at the start of studio and must
be uploaded to Canvas.

K. General Information
1. The device must be activated by using a push button switch attached to your microcontroller.
2. The faculty’s and TA rulings are binding and final.
Rev. 1 (10 February 2021) 53. Your system performance will be recorded by a TA during in-person timings in open studio
or during studio section. You will run 3 consecutive trials. Each trial has 3 minutes available
for setup, 1 minute for execution, and 1 minute for clean up. The next trial must be started
within 3 minutes of the last trial. No redos/retrials are possible.
4. No actuators (e.g., valves, solenoids) can be pre-activated prior to the start of a trial, or after
the end of a trial. Actuators must be in their resting state at the start and end of each trial.
5. The device must be safe. It must not damage, stain, or permanently change the competition
arena and competition items or its surroundings. No adhesives and no Velcro-type materials
(e.g., hook and loop binding) may be used to interact with the arena or the competition items.
It must not injure bystanders or you. The faculty will disqualify any device they deem unsafe,
resulting in zero points for the round.
6. Once it has been activated, you may not touch, or even appear to touch, the device until the
staff member in charge of the competition arena indicates it is time to clear out the arena.
7. The source of power in your device is limited to five mousetraps, power provided to your
system from a controller box, the mechatronics kit components, five #64 rubber bands, and
gravity. No other devices that store energy are permitted. Air from the pneumatic tank may
only be used to power pneumatic actuators, and may not be vented directly to the
environment. Rubber bands that do not release energy (e.g., as treads on tires) do not count
towards the total. The only powered actuators that you are permitted are the ones that are
supplied to you by the ME 2110 staff. You may purchase additional sensors as long as your
budget remains under $100, and as long as you are provided with email consent from the
Head TAs. Purchasing information must be submitted to the Head TAs ahead of time, and
this purchasing information will subsequently be published on the course website once
approved.
8. No group may spend more than a total of $100 on the final device. You will be required to
document cost of materials by submitting receipts as well as a bill of materials (BOM).
Material may be prorated for costs. You may use free material; however, the BOM must
show cost of that material as prorated from some verifiable source. The object cost is defined
as that which Joe P. Citizen must incur in obtaining the object. For donated or scrounged
material, an equivalent price must be specified. The cost of the mousetraps, sensor and
supplied actuators is NOT included in the $100. The $100 is out of pocket expense; you will
not be reimbursed by the School. The costs of any aesthetic materials (e.g., paint) and
fasteners (e.g., staples, tape and glue) are not included in the $100.
9. The device shall not be permanently bonded in any manner to the competition arena or its
surroundings in any way. The mechatronics components shall not be permanently bonded to
the rest of the device (e.g., no glue or epoxy fastening components down).
10. The device must operate autonomously. No remote control is allowed.
11. The device may not utilize or interact with any living person or living object during the
competition.
12. All of ME2110 is to be conducted in a professional manner and, therefore, any inappropriate
language or behavior will result in loss of points / disqualification.
