Voice Controlled Robot Arm
How This Exhibit Works:
Prior to using this exhibit you must program the
robot arm’s control panel to recognize your voice commands. The computer is totally literal, so be careful to correctly state
commands. When each command is stated during use, the arm will latch the
When you are ready to command the motions of the Robot
Arm, remember to say “Stop” when terminating a command or it will keep going.
Example of correct command
language is: “Forward – Stop”, “Clockwise – Stop”, “Down – Stop”,
“Counterclockwise – Stop”. As you can see the voice commands always are followed
by the “Stop” command to terminate the last action. If the “Stop” command is not
used the commands combine and the arms motions will keep going or cancel each
other out. If such an error occurs the “Stop” command ends the error.
The only exception to
this command protocol is the hand function, which is addressed as “Open” or
“Close” without saying “Stop”. This allows the hand to have a constant grip on
objects while other commands are being stated.
To program the
unit you will be prompted to speak the command and then to repeat it again. This
will give the computer two examples of each command to build a voice pattern
map, which it uses to compare to your voice commands.
Keep in mind that the control uses speaker dependant
voice recognition, so in effect it learns to recognize your distinctive
voice patterns. In theory this means that the controls can learn to recognize
other words as having the same meaning. This allows the control panel to
be reprogrammed to recognize different types of speech, accents or languages.
robot arm moves by the use of a series of servos, a control board and a series
of limit switches. The limit switches limit the travel and allow the arm to feel
its surroundings. They also restrain the arm from crashing into objects. In this
respect the arm is capable of adapting to a changing environment and refusing
the users commands if the commands would result in damage to the arm or objects
The arm has pressure
sensitive and end of travel limits, and can adapt to any arrangement of objects
stacked in it’s path. It is made of light weight 6061 Aluminum. This arm is
totally open framed for educational viewing and based closely on the proportions
of an actual human arm. It is especially designed with safety features and force
Built in logic allows robots to act as a mechanical
assistant and simple electronic brain. In the ideal case this accents the
human user potential to perform a given task.
Try to control the arm using the voice commands. Attempt to pick up an
object and set it on one of the pedestals in the exhibit activity area.
The Voice Controlled Rail Robot Arm exhibit features
a thirty five inch long electromechanical robot arm mounted on a rail system which allows the arm to glide from
one end of the exhibit to the other. The exhibit's unique configuration
allows the museum visitor to guide the arm by direct view through polycarb
windows and by voice control.
The entire middle run of the exhibit is totally
encased by clear polycarbonate which allows many of people to view the
exhibit while it is being operated.
The electromechanical arm is designed in a totally
open format, all the parts and the key components that operate it are visible
for maximum educational merit. Each finger and thumb independently operate.
The wrist turns, the elbow moves, as does the shoulder through both the
horizontal and vertical axis. The rail is comprised of two tubular steel
guides, aircraft grade cable and UHMW mounts. The gear motors that operate
the rail and arm are quality Dayton gear motors. The fingers and thumb
are actuated by Bicron electric solenoids.
The exhibit provides an unique format to study
the engineering principles of a robot arm. The exhibit case is made
of quality MDO ply and covered with your choice of lamenient and accented with
brushed aluminum detailing. The exhibit approximate measurements are 8 feet long
x 7.5" high x 40 inches wide (less the control council). The control council
adds an additional 16" to the width which extends the center to 56" wide.

exhibits have a long service life expectancy, with many units still
functioning smoothly at 10 years plus. They are so easy to maintain and
repair, that it usually takes regular museum staff only 15 to 20 minutes.
