King Of The Hill
Coordinator: Bob Mullin firstname.lastname@example.org
design and build a robot following the guidelines listed
below. In the contest, two robots race down a 4’ x 8’
playing field which has a narrower opening mid-way down
the board just large enough for one vehicle to pass
through. They retrieve one of two ping-pong balls, and
then deliver it to a hole on top of a small hill next to
where they started. They may also keep their opponent
from scoring. Design (creativity or complexity) and
workmanship are important only in achieving a well
functioning robot. Vehicles will not be judged on
of projects from prior year Tech Wars competitions!
can utilize any tools or machines to build their
competitor will have a designated ping-pong ball
their robot will retrieve and attempt to drop into a
hole on top of the hill to score in the match.
will consist of best two out of three matches.
limits will be set for rounds, timeouts, repairs,
etc. at the event.
robot falls off or gets hung up on the playing
field, it will forfeit that match.
to Robots in Competition:
purchased R/C vehicles can be used and/or modified
for use in the competition. Projects have to be
student built, NO EXCEPTIONS!!!
explosives, corrosives, flames or pyrotechnics.
projectiles, or radio jamming.
electronic weaponry such as stun guns, tesla coils,
heat guns, etc.
entanglement devices - string, tape, fishing line,
weaponry such as water, glue, foam, etc.
physical interference or poor sportsmanship between
or electromagnets - may cause radio interference.
No cutting devices - Any major damage to the arena
will result in disqualification
Size of robots is 12” wide x 12” long x 12”
high (robots will have to fit completely into a
12”x12”x12” box before competition takes place).
microprocessors or electronic speed controllers –
this is an entry-level robot competition using
servomotors. All competitors begin with the same
parts to propel the robot, so the best physical
design to accomplish the task becomes the main
replaceable frequency crystal radio control system
AM, FM, Surface or Air: transmitter, receiver, and

1 – 4.8
volt NiCad Battery or comparable depending on the
radio and receiver chosen.
servos (example: Futaba FP-S3003 or FP-S3004).
Servos may be modified (as in the case of Air RC
systems in which the throw is not a full revolution,
see Tech Wars Web site for this modification).
Transmissions and gears may be used.
materials and design is up to the competitor.
There is no limit to cost
be competition based. Win two of three in a match and
you move on in bracket-style elimination. The
competition is engineering function based. The best
engineering ideas to capture and carry the ping-pong
ball will be successful.
