Products developed by Theta Engineering

Robotic Cell Phone Programmer

Designed and programmed custom stepper motor driver boards for a robotic cellular phone programmer. This project involved inter-processor communication between 8 Microchip PIC-family microcontrollers supporting simultaneous motion of up to 7 axes.

Robotic Arm Test System Project
Designed and built 4 different automated test fixtures for Beckman Instruments (now Beckman Coulter). The unit pictured uses a combination of pneumatics and electronics for measuring the force and accuracy of a robotic arm which is itself a component in one of Beckman's medical lab instruments.

Digital and Embedded Systems Design

An Embedded Microcontroller or DSP system is made of Chips, Circuits and Firmware. The digital voltage levels, speed, bus width, fan out, power consumption are some factors that a designer has to keep in mind. As portable and wireless gadgets are becoming more popular, RF, Ethernet and Energy Efficient Design aspects should be studied. Power electronics and Analog Circuits knowledge is used around the system, all this is integrated to make an instrument, equipment or gadget.

Embedded Systems Design

Microprocessors and Microcontrollers

Analog devices like transistors and diodes lead to opamps and analog computing. This takes more parts but with fast devices can be real time. Then came Logic and Digital Circuits, here also big systems will take too many parts. A very Old hp Logic Analyzer instrument, could be HP1600A, had more than five large PCBs, Toggle Switches and numerous 74Fxx TTL Chips. I tried to revive it, it could not be fully restored.

Microcontroller - 8051, 8052, OpCodes, Analog and PC Interface.

Then came the solution the Microprocessor. Here the entire system goes into the firmware and a Hardware Tool Set in the Microprocessor made up of Logic and Math is sequentially used to perform the same operation that would require innumerable Gates in a plain hardware digital circuit. But as it performs the operations one after another, it takes time and is defined by the CPU Clock Speed.

When the External RAM and EPROM and other peripheral devices moved into the main package, MicroController were born. When more external devices merged with the MicroController. It formed a nearly complete computer, this is known as the SOC.
