Science and Electronic Kits

Speech Controlled Robotic Arm

The SCRA-01 incorporates three kits; the OWI Robotic Arm, SR-06 Speech Recognition Circuit and the SRI-01 OWI speech interface circuit. By connecting these kits together you create a powerful speech control system capable of controlling the OWI-Robotic Arm Trainer using voice commands.

The SR-06 speech recognition circuit allows you to train any word(s) in any language to control the robotic arm.

You can purchase the kits separately and build your system slowly or purchase them bundled together. Kits may be purchased as kits needing assembly or assembled and tested. see prices below.

Speech Recognition Kit

The SR-06 Speech Recognition Kit is a stand alone circuit that can recognize up to 40 words (user selected words) lasting one second each or 20 words (user selected words or phrases) lasting 2 seconds each. The speech recognition circuit is multi-lingual, words to be trained for recognition may be in any language.

Speech Recognition Interface w/ Relays

The Speech Recognition Interface SRI-02 is an interface board for the SR-06 and SR-07. The circuit incorporates ten relay switched corresponding to the first ten target words of the SR-07 Speech Recognition Circuit. Each numbered relay has a single-pole double-throw (SPDT) switch rated at 125 VAC at 0.5 amps or 24 VDC at 1.0 amps. Using this interface easily allows the speech recognition kit to activate or deactivate 10 electrical circuits or devices.

Speech Recognition Interface

The Speech Recognition Interface SRI-03 is an interface board for the SR-06 and SR-07. The circuit incorporates ten logic outputs corresponding to the first ten target words of the SR-07 Speech Recognition Circuit. Each numbered output is brought high (+5V) when corresponding trained word is recognized. Using this interface allows the Speech Recognition Kit to active or deactivate 10 electrical circuits or devices using the TTL logic signal.

Speech Recognition Interface for Robotic Arm

The Speech Controller Kit connects the SR-07 Speech Recognition Kit to the OWI 007 Robotic Arm Trainer to allow control of the robotic arm using voice commands. Each robotic function is controlled by a spoken word. The user trains the SR-07 speech recognition circuit to recognize their voice and commands. Users can select their own words to control robotic arm function.

Robotic Arm

The Robotic Arm teaches basic robotic principles. Using the servomotor controller one can control the arm to grab, lift, lower, wrist move and pivot. The PIC16F873 micro controller used in the servomotor controller will be freely updated for one year to incorporate the Windows PC program and speech recognition hardware scheduled for release in November 2004.

OWI Robotic Arm and PC Interface Kit

The OWI 007 Robotic Arm Trainer teaches basic robotic sensing and locomotion principles while testing motor skills as you build and control the arm. Using the wired control one can control the arm grab, release, lift, lower rotate wrist and pivot sideways 350 degrees. After assembly, one can observe the gear mechanisms through the transparent arm's plastic. Five motors and five joints allow for good flexibility.

The robotic arm interface kit connects OWI's 007 Robotic Arm Trainer (tm) to a personal computer, (IBM PC or compatible). The interface connects to the PC's serial port. The software for the interface permits real time control and contains a built-in interactive script writer demonstrating computer controlled automation and animatronics. The Robotic Arm PC Interface creates a fun way of learning and experimenting with computer automation and animatronics.

Servomotor Controllers PC & Manual Control

Servomotor Controller boards allows you to control servomotors. We have three servomotor controller models available. The four and five servomotor controllers allow you to control each servomotor independently via the onboard three-position switches, or using a Windows 98/XP program. The PC program allows speed control and script writing.

The eight position servomotor controller is only PC control. PC control is through an available USB port. Three pin headers make it easy to connect servos - just plug them in. Uses either a 9V battery or AC adapter. All windows servomotor programs are available to download, click on picture to proceed to download page. Servomotor controller boards are available in kit form or pre-assembled and tested, servomotors not included but are available for purchase on this web site.

Touch Tone (DTMF) Reader

Dialed phone numbers, repeater codes, control codes, anywhere touch tones are used your TG2 will decode and store any DTMF tone it hears. A simple hook-up to any radio speaker or phone line is all that is required. The Flash storage capacity of the built-in micro controller allows the circuit to store 640-digit numbers for 10 years, even with the power turned off. The bright 8-digit display lets you scroll through the stored numbers at your leisure. To make it easy to pick out numbers or codes, a dash is inserted between any group or set of numbers that were decoded more than 3 seconds apart.

Added features include an onboard RJ11 phone jack for easier phone line interfacing and an output latch jack offering an external trigger source when a user specified number ( 1 to 60 digits) matches the monitor input. The TG2 runs on any 8 to 15 volt DC power source and is both regulated and crystal controlled for the ultimate in stability. Click on photograph for more information.

Electrocardiogram (ECG) Heart Monitor

Enjoy learning about the inner workings of the heart while at the same time covering the stage-by-stage electronic circuit theory used in the kit to monitor it. The three probe wire pick-ups allow for easy application and experimentation. The documentation covers circuit descriptions and heart function. Multiple beat indicators include a bright front panel LED that flashes with the actions of the heart, an adjustable level audio speaker output and a monitor output to view the traditional style ECG/EKG waveforms on an oscilloscope. Uses 9V battery (not included) This is NOT a medical device, it is intended for hobbyist usage only. Click on photograph for more information.

Wimshurst Machine

This machine produces large static electric sparks for a terrific classroom demonstration. No assembly required, simply attach the hand crank, begin cranking, and watch in wonder as the sparks fly. Instruction guide and helpful hints are included with each unit. Unit consists of two high resistance 25cm plastic discs, with equally spaced metal sectors. The discs are supported in two rigid upright supports, rotating in opposite directions with a hand crank.

Provided with a system of induced charge collecting brushes, adjustable ball-ended electrodes, and cylindrical Leyden jar capacitors for obtaining higher potentials. Produces substantial opposite charges, which are deposited in the capacitors and on the metal spheres. A rapid sequence of sparks can be generated by lowering the system capacitance (moving the metal spheres closer together). Mounted on an insulated wooden base.
