Hexapod Robot III

MHEX II Walking Hexapod

Mhex II is an omnidirectional hexapod (6 legged) walking robot.
Each leg has 3 motors which allow the feet to be placed
anywhere in 3D space within mechanical limits. Unlike my first
hexapod robot (MHEX), this configuration allows the robot
to walk in any direction keeping it's feet fixed at a point on
ground without slipping.

An 18-DOF hexapod robot developed at the University of Florence

An 18-DOF hexapod robot was complete designed and
developed at the University of Florence by Andrea Foschi in
2005. It was later tamed by Marco Natalini and Alessandro
Mambelli using Evidence Srl's FLEX Light board and ERIKA
kernel. The main purpose for adopting FLEX is due
to its low-cost development kit that permits easy addition
of features i.e. sensors and behaviour. Since then, a number
of students have worked on this hexapod. The future version
would use the FLEX Full board.

Hexapod - Build Blog

Our design for the first hexapod is simple. It is supposed
to be a prototype for a more complex robot that we will
build this fall. The design includes three servos per leg.
One servo will rotate the leg while the other two perform
the functions of a hip and a knee.

Stiquito is a small, inexpensive hexapod (i.e., six-legged) robot.
Universities, high schools, and hobbyists have used
it since 1992. Stiquito is unique not only because it is so
inexpensive but also because its applications are almost limitless.
The propulsion in these robots is nitinol, an alloy actuator wire
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.
