WARNING!
DISCLAIMER
This presentation was prepared
using draft rules. There may be
some changes in the final copy of
the rules. The rules which will be in
your Coaches Manual and Student
Manuals will be the official rules.
2
Goal
Design and build a robot (remotely
operated vehicle)
 Must perform certain tasks on a
prescribed playing field

3
Construction

Robot may be controlled remotely:
◦
◦
◦
◦

Radio
Infrared
Wired control boxes
See soinc.org for legal devices and frequencies
Commercial robot – at least one
functional modification
◦ Lack of modification means Robot doesn’t
work or will work differently
4
Construction -Size

Robot, in ready to run position
◦ Fit, entirely, (without compression) in a 30cm
x 30cm x 30cm cube
 Entirely means that no portion of the robot,
including the antenna, has its position changed by
the box
 If no box is used, no portion would ‘stick out of’ that box
◦ Robot may change dimensions during the run
 May get larger
◦ May not separate into two or more active
components
 May drop passive parts
5
Motions

Must be powered only by electrical,
elastic, or gravitational energy
◦ These forms must not be converted to other
forms such as hydraulics or pneumatics
6
Powered by

Commercial batteries may be used to
energize each of the Robot’s and its
controller’s electrical circuits
◦ Not exceeding 14.4 v as labeled
◦ May be connected in series or parallel
 But must not exceed 14.4 v

Must be contained in either the Robot or
as part of the controllers
7
Frequencies

Permitted frequencies will be listed on
the Science Olympiad national website at
www.soinc.org
◦ 2014 events
 Robo-Cross

Technical documentation

Teams must develop and submit at
◦ Check-in or inspection or as announced by
tournament director the following:
◦ Illustration
◦ Operating Description
◦ Written practice log

Operating description
Robot reaction to each control input
 Tentative/Proposed plan of movement

◦ Which items in the Competition Area will be
moved
◦ How the robot plans to move each item
 This is a tentative plan – no deductions if plan must
be changed during operation
15
Tentative Plan of Movement
Move Robot into Zone C, stand the Bonus Box upright and
push it into Zone B, towards middle of the Zone.
Back out to Zone A/B boundary and begin to pick up ping-pong
ball, AA cells, and Lego blocks and drop into Bonus Box
Pick up tennis ball and drop it into Bonus Box
Move further into Zone B to pick up remaining Lego blocks, AA
cells, and ping-pong balls and drop into Bonus Box
Maneuver Bonus Box into Zone D
Drive Robot into Zone D
Turn off Robot and shout “Stop”
16
Written practice log
Record at least 5 runs
 Record at least three parameters

◦ Must include score
◦ Must include time
◦ Any additional parameter

Playing Field

4 ft x 4 ft smooth, rigid surface
◦ Tempered hardwood, Masonite, sanded
plywood, etc.
 Robot must be able to operate on all such surfaces

Perimeter of 1” x 2” wood (nominal)
attached with the 2” dimension placed
vertical
19
Playing field
Divided equally into square zones, labeled
A, B, C, D counterclockwise.
 Zone D will have a border of 5/8 in.
quarter round molding separating it from
other zones. Rounded sides will face
Zone A and Zone C.

20
Playing field
Interior boundaries drawn with fine
tipped marker
 Zone A will have a box 30.0cm x 30.0cm
drawn for the starting position of the
Robot.
 Zone B will contain all of the items listed
in 4.i at the start of the competition.

21
Playing Field

May be designed to fold or separate
◦ No more than a 3mm gap or step
◦ Tape may be used to secure the seams

All materials for the event, playing field,
Bonus Box, and items, will be supplied by
the Event Supervisor
22
Playing Field
Bonus Box must be the bottom of a
plastic gallon milk jug cut off to a height of
14.5 to 15.5 cm
 Must be placed in the inside corner of
Zone C with the open top facing away
from Zone D

23
Items
4 Ping-Pong Balls
 4AA batteries (on their sides)
 1 tennis ball

Competition

At check in (or inspection), ES inspects
and weighs the device
◦ Checks size
◦ Selects 4 items from the technical
documentation and has the competitors point
them out on the device

Students place their Robot in the
designated Starting Position, in ready to
run configuration
26
Competition
Event Supervisor will count aloud “1. 2,.3,
Go”
 Time starts (recommended 3 timers be
used)
 Teams will have 3 minutes

27
Competition
Robot may move the Bonus Box but the
Box must remain inside the playing field in
any zone
 If any item moved by control wires, it is
out of play – no points for it
 Miscellaneous parts may end up in or on
the Bonus Box without penalty

28
Competition

The run must stop (and time recorded) if
any of the following occurs
◦ 3 minutes have elapsed from the word “Go”
◦ The team says “Stop”
◦ Any part of the Robot or Bonus Box is ‘Out
of Bounds’
 Out of Bounds is defined as touching the floor
outside of the Playing Field
◦ The Robot is physically moved by the wires
connecting it to the control box
◦ A team member steps on the Playing Field
after the team has received a warning
29
Competition
The robot must stop within 2 seconds of
the run completion
 Any items moved or moving after time
has stopped must be scored where they
were prior to the time stopping

30
Scoring

At the end of competition, points will be
awarded based on the number and types
of items that are in the specified scoring
areas
31
Scoring - Robot

If the Robot (parts touching the ground)
is completely in:
◦ Zone B – 3 points
◦ Zone C – 5 points
◦ Zone D – 15 points

If Robot parts (including dropped parts)
touch the ground in multiple zones, the
lesser zone score will be awarded

Each item may earn points for only 1 single zone
2x score multiplier to any items completely under the Bonus Box
3x score multiplier to any items in or fully supported by the Bonus Box
if the opening is pointing up
Any item which touches the floor outside of the Playing Field at any time,
even if under control by Robot, is out of play and has no point value
33
Scoring
If any part of the Bonus Box is Out of
Bounds, the items within will have no score
value
 Score will be reduced one point for each
incorrect answer in 5.a (book may say 5.b)
 Teams with no or incomplete Technical
Documentation will have 5% deducted from
their score
 Maximum score is 183
 High score wins

34
Scoring

Tie breakers
◦ Shortest run time
◦ Lowest mass of the Device
 Robot and Controllers
35
Scoring

Tiers:
◦ Tier 1: Devices that meet all requirements are
ranked by highest score
◦ Tier 2: Devices with competition violations
◦ Tier 3: Devices which fail to meet a spec under
“Construction Parameters”
◦ Participation Points only: Devices which violate
the frequency rules or are unable to compete
◦ No show points only: Devices that have no
capability by design to score points by moving
objects
36
Kickstarters
The following YouTube videos probably
will not run when you try this
powerpoint at home.
 All you need to do is go to YouTube and
type Science Olympiad Robo-Cross in the
search box. I found about 15 videos.
 Remember – these designs were
operating under different rules than you
will.
