The final lab is designed to be a fun experience, combining some elements of prior labs and
homework assignments. The lab is very open ended as to encourage innovative and interesting designs.
Each robotís goal is to autonomously find the opposing robot on the world and push the other robot off the world without damaging your
opponent. Each robot will bear a light source to help you find your opponent. There will be barriers constructed around the edges of the world
in order to make it easier for the robots to identify the limits of the world.
The world's size or shape will not be disclosed. All you need to know is that the world will be
symmetrical and convex in its design. There will be no obstacles on the world, but the stability and grip
of the terrain is somethining that should be considered.
The robot must fit within an 8 x 8 x 7 (width x length x height) inch box, there needs to be one spot
on the robot that's close to 7 inches high so that the lights can be attached to that spot. The lighting in itself takes up
about 1 inch, but that will be the TAs problem to attach.
Movable appendages are allowed on the robot as long as they fit within the box requirements at checkpoint
time. Keep in mind that if you use appendages to manipulate the other robot, that you are careful not to
damage the other robot. The policiy is, if you break something, you buy it! No matter what the original
intention of your design was.
The maximum weight that the robot can be, is 5 lbs. There is no reason that your robot should be heavier than
You are not limited to using lego parts, so be imaginative. The only bulding restrictions are:
No combustible parts
Electric Motors only
No prebuilt kits, cars
Handyboard has to be explicitly shielded inside the robot and cannot be used as any sort of shield.
The handyboard has to be within the "belly" of the beast!
No material can cost more than $10 and the total cost cannot exceed $50.
Below is a side and bottom picture of the light mounts that will be used on the robots. The light mounts
will be omni-directional, so there is no need to worry about not seeing your oponenet. The light mount uses
blue led lights and has its own batteries within the mount, therefore the teams don't have to worry about powering
the light source. Study the light mount carefully, and remember to have at least one point on your robot of
exactly 7 inches height that is big enough to mount the lights on it. Make your robot design so that the light
can be easily attached.
You will be evaluated on how well you pass the checkpoints prior to the competition as well
as how well you perform during the competition. Note, once the competition starts, no changes to the robot
will be allowed, unless a piece of the robot falls off or something is broken.
Teams will be paired together successively in double elimination bouts until there is only one team left. That team shall be the grand champion. The grand champion will receive the prize designated by Professor Choset (a 100% on the final).
Before the competition, each team will undergo a checkpoint. You may not enter the competition unless you have passed the checkpoint.
The competition will be held in the REL on Wednesday May 3rd. All the teams should be present at 10:30 and be ready to start the
competition right away. The competition will officially begin at 10:35.
The enviroment will be an undisclosed shape. It will be made out of felt, edged in aluminum foil. The edges will
be at least an inch and a half thick. The enviroment itself will be elevated off the ground. The fall from
the enviroment's edges will be padded in order to prevent the robot from taking damage if it falls of the world.
Rules of the Competiton
The bouts wil begin with the TAs placing the two robots on the board and pressing the start buttons to activate
both robots. Teams need to program their robots in such a way that they don't start moving until the start
button is pressed. A bout ends if a robot has fallen of the edge of the world or if 5 mintues have elapsed. In the
event of a tie, both robots will get a loss. This is done purposely in order to encourage more offensive rather
than defensive designs. The tournament is a double elimination tournament, thus each robot needs to lose twice before
it is taken out of the competition.Again, your robot must attempt not to hurt other robots. If your robot is deemed
to be reckless, it will not be permitted to compete. If you have any questions about your robot design, e-mail or
personally ask the TAs.
|Robot pushes light off world
|Robot doesn't fall off while pushing light
|Robot detects edge of the world (stops at the edge if light is off the world)
|Robot follows a moving target
||70 / 100|
Since because of the competition design, some teams will lose and some will win, the teams
that lose while giving a fight, shall be credited with points too. The points categories for
losing a match are:
Lasting more than 30 secs - +1
Lasting more than 1 min - +5
Lasting more than 2 mins - +10
|Robot wins the first match
|Robot wins second match
|Robot wins third match
|Partial Credit for loss
||30 / 100|
Checkpoint Times and Grading Sheet
Note: Checkpoints need to be done prior to competition day and have to be done
during one of the scheduled times slots below. All checkpoints will be held in the REL
