Stiquito

Last updated

Stiquito (pronounced sti ke to) is a small, inexpensive hexapod (i.e., six-legged) robot commonly used by universities, high schools, and hobbyists, since 1992.

Stiquito's "muscles" are made of nitinol, a shape memory alloy that expands and contracts, roughly emulating the operation of a muscle. The application of heat causes a crystalline structure change in the wire. Nitinol contracts when heated and returns to its original size and shape when cooled.

Stiquito was developed by Jonathan W. Mills of Indiana University as an inexpensive vehicle for his research. He soon found its applications extended to educational uses. It has been used to introduce students to the concepts of analogue electronics, digital electronics, computer control, and robotics. It has also been used for advanced topics such as subsumption architectures, artificial intelligence, and advanced computer architecture.

These books contain instructions for building the Stiquito robot, instructions for designing and building control circuits, and examples of student projects that use Stiquito. Most importantly, the books contain all the supplies needed to build the robot.

The first book was compiled from material written between 1991 and 1996. The chapter has more of a "research" feel since it shows the base robot and slight variations and applications of it.

The second book was compiled from materials written specifically for education. It includes instructions of control using supplemental kits.

The third book is also educationally-based. It is a slight departure from the first two books because the third book (and the included kit) are centered around a microcontroller board and its leg actuation electronics.

A microprocessor is a computer processor where the data processing logic and control is included on a single integrated circuit, or a small number of integrated circuits. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer's central processing unit. The integrated circuit is capable of interpreting and executing program instructions and performing arithmetic operations. The microprocessor is a multipurpose, clock-driven, register-based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory, and provides results as output. Microprocessors contain both combinational logic and sequential digital logic, and operate on numbers and symbols represented in the binary number system.

The 6800 is an 8-bit microprocessor designed and first manufactured by Motorola in 1974. The MC6800 microprocessor was part of the M6800 Microcomputer System that also included serial and parallel interface ICs, RAM, ROM and other support chips. A significant design feature was that the M6800 family of ICs required only a single five-volt power supply at a time when most other microprocessors required three voltages. The M6800 Microcomputer System was announced in March 1974 and was in full production by the end of that year.

A microcontroller is a small computer on a single VLSI integrated circuit (IC) chip. A microcontroller contains one or more CPUs along with memory and programmable input/output peripherals. Program memory in the form of ferroelectric RAM, NOR flash or OTP ROM is also often included on chip, as well as a small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications consisting of various discrete chips.

An embedded system is a computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system. It is embedded as part of a complete device often including electrical or electronic hardware and mechanical parts. Because an embedded system typically controls physical operations of the machine that it is embedded within, it often has real-time computing constraints. Embedded systems control many devices in common use today. In 2009, it was estimated that ninety-eight percent of all microprocessors manufactured were used in embedded systems.
