MRISAR's Voice Controlled Rail Robot Exhibit
Tell the Robot what to do!
How It Works: The Visitor programs the control panel to recognize voice commands. When each command is stated during use, the arm will latch the command. 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. 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. Keep in mind that the control uses speaker dependent voice recognition, so it learns to recognize your distinctive voice patterns. This allows the control panel to be reprogrammed to recognize different types of speech, accents or languages. Activity: 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 robot arm moves by the use of a series of gear motors, 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 surrounding it. The arm has pressure sensitive and end of travel limits, and can adapt to any arrangement of objects stacked in its path. It is made of light weight 6061 Aluminum. This arm is totally open framed for educational viewing which relates to STEM and based closely on the proportions of an actual human arm. It is especially designed with safety features and force limits.
Specifics: The Voice Controlled Rail Robot Arm exhibit features a 35" long, nine range of motion, 5 finger 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 activity is encased by clear poly-carbonate which allows many people to view the exhibit while it is being operated. The exhibit is designed in a totally open format, all the parts and the key components that operate it are visible for maximum educational merit. The Hand closes, the wrist turns, the elbow moves, as does the shoulder through both the horizontal and vertical axis. The exhibit provides a unique format to study the engineering principles of a robot arm. The exhibit approximate measurements are 8” long x 8’ high x 40” wide (less the control council). The control panel adds an additional 16" to the width which extends the center to 56" wide.
