Concept

• The goal of this project is to create a robot
  that can implement our knowledge in EE while
  creating something entertaining.
• There are similar devices on the market right
  now, but none as sophisticated as the one we plan
  on creating.
• With some additional programming, our robot will
  be able to do much more than merely entertain
  people.

Internal Design Mechanical

• After experimenting with some of the equipment we
  will be using and visualizing the effect of servo
  motors, we have decided on much of the inner
  mechanics of our robot
• 6 motors/servos for each arm, 2 for the head,
  one for the waist, two rotational motors for the
  wheels.

Internal Design Electrical

• With the addition of the wireless component to
  our robot we will need to add a little more space
  for the transceiver and required board. Also
  added aesthetic LEDs to our design
• 1 transceiver and required mount, 1 mini-dragon
  board, assorted resistors, assorted capacitors,
  LEDs (eyes and transmission indicator)

5
Casing Design

• Our original idea of making a life-like robot out
  of aluminum, has been modified slightly, we need
  more space in the base for the transceiver board.
  Also we moved the powered wheels to the rear of
  the platform and added rotational wheels to the
  front of the platform for stability.

General Design Specs

• 1 foot by 1 foot base dimension
• 1.5 feet height
• Shoulder to elbow 6 inches
• Elbow to wrist 4 inches
• Head 4 inches diameter
• Eye x 2 1 inch diameter

Apart from Robot

• We need to make a transceiver circuit that is
  compatible with our computer, so that the two
  transceivers can communicate. Circuit Design
  Available.
• Quiet environment and decent quality microphone.

Voice Recognition

• The SDK/Julius package that we are working with
  has some impressive capabilities, and we have
  found that with it we can make a program that not
  only will decode voice signals, but it can be
  programmed to use our wireless communication
  circuit as well.
• Program in development hope to demo in 2 weeks.

10
Mini-Dragon Programming

• We are currently still learning the basics of
  loading a program in the mini-dragon board. But
  we now know a general method for operating LEDs
  and running motors.
• Our next step will be finding ways of
  communicating with other devices via transceivers.

11
Additional Information

• In order for us to have sophisticated movement in
  our robot, we are going to need to spend a lot of
  time planning our timing structure. Sequencing of
  motors.
• Much of the second quarter will be spent doing
  this.

12
Planned Project Deadlines

• We hope to have all the equipment received and
  ready for construction, and the voice recognition
  program ready to go in 2 weeks.
• We hope to complete the construction of the robot
  and mount all the parts by the 1st day of next
  quarter.
• We plan on using next quarter to create and
  improve the program used to control our robot,
  and communicate with the computer.
