We imagine that the next generation of
computer games will have a new dimension …
Exotic, real world,
robotic characters that
jump right off the screen
onto a real playing field.
The entire environment
will be computer
controlled.

Game Play
Basic types of computer games.
• Kick / Box
• Race
• Strategy
• Shoot / Score Simulations

The Playing Field
When a kicker scores,
the ball goes into the
goal and rolls through a
tube with a light sensor.
A sensor on the ball
rack detects when a
ball is kicked. It
starts a timer and
keeps track of the #
of balls kicked.

1st Game Design Step – Objective/Rules
Rules:
Kicker is a robot that kicks a ping pong ball into a 18" wide goal
from a distance of 24."
Goalie is a robot that has a 6" wide hand and can go left or right.
Kicker Rating:
p = % of goals vs. 7 kicks
t = time to kick 7 times
Kicker rating = p * 100 * (1/t)
Goalie Rating:
g = # goals scored
k = # kicks
Goalie rating = g/k *100

Data Collection
A sensor in the goal measures the number of balls that get into
the net.
A sensor on the ball setter starts a clock when the 1st ball kicked
and stops the clock when 7th ball is kicked.
This ball setter sensor also records how many kicks are made.
A robotic referee will read the sensors and report the results to
the scorer's table (i.e. Excel application on the Windows computer)

Ranking System
Each robotic player has a profile including statistics and playful
information in an Excel template.
The scorer’s table Excel spreadsheet will calculate the ratings,
update the rankings, play multi-media files, return ranking
information to individual profiles, and send control signals to the
robotic scoreboard, referee and fans.
