Remember !!
These are just some ideas, there are many ideas
out there and much more in your minds ;)

Presentation Skills
Why
 What
 How
 Who

Planning Content
• Analyze your AUDIENCE.
• Define what ACTION you want them to
take.
• Arrange your ARGUMENT to move
them.
3 A’s

Focal PointI have a Dream “Martin Luther King”

How Do We Communicate
Tone
Words
Body language
Research has shown that the following is true.
Words 7% Tone 38% Body language 55%
38

Eye Contact
• Never let them out of your sight.
• Looking them in the eye makes them feel that
they are influencing what you say.
• Eye contact allows the presentation to
approximate conversation.

Body language
No-No’s
 Lean on or grip the podium.
 Stand Immobile
 Use a single gesture repeatedly.
 Examine or bite your fingernails.
 Chew gum or eat candy.
 Click or tap your pen, pencil or
pointer.

Body language
No-No’s
Crack your knuckles.
Tighten your tie or otherwise play
with your clothing.

Robista Competition
STP’14
Finally !!!!!

Rules
Max. Base dimension 30*30 Cm, and the width of the road
will be 50 cm .
Length of the flag is 20 Cm and its weight won’t exceed 50
gm.
The first flag will be on the ground level and also be put on
the ground level, and so on …….
All flags will be in position at 20 cm away from the robot
because of the barrier.
Each team will start the competition with zero points, and
the team that will end with the highest score will be the
winner.

Rules
Catching a flag with the robot gripper (+10).
Putting the flag in place properly (+10).
In case the robot dropped the flag before
reaching its red hollow point (-5) , but he can
pick it from the ground again to complete the
mission.
Max Time for all missions is 20 Min.
Each robot has 4 missions catch and put 3
flags and reach the end point so the average
time of each mission will be 5 minutes.

Rules
If team complete any mission before 5
minutes they will get Bonus “for
example: the faster will take (+6) and the
follower will take (+5) and so on”.
If team exceeds the 5 minutes duration
for the mission they will get (-1).
If a team break any rule they get (-5).
Moving the robot automatic on the field,
and catching & putting the flag manually
(+10).
Moving the robot manually on the field
(-5)

Additional Criteria
Catching & throwing the flag automatically.
Best circuit Design.
Best Code.
Best Mechanical Design.
Number of motors.
Little money.
Team work “each member in the team should
participate almost in all tasks”.
Presentation about your product.
