 Hexapod
The hexapod control: as previously mentioned, any change in one of the struts angle or length, there will be a change in all the other struts.
Since most medical disciplines, especially in the field of surgery, require high accuracy and controllable forces when working on human organs, the precision controllers were introduced to the field of medicine as well.

 JP Brown's Serious LEGO - Hexapod_I
Hexapod_I's step rate (about one step every three seconds) is slower than Flik and the reasons are interesting.
The ground covered by an articulated hexapod design such as Hexapod_I is proportional (all other things being equal) to the angle through which the articulation points move.

 Encyclopedia4U - Hexapod - Encyclopedia Article
There is also some evidence suggesting that the hexapod groups may not share a common origin, and in particular that the Collembola belong elsewhere.
The myriapods have traditionally been considered the closest relatives of the hexapods, based on morphological similarity, but new work has called this into question, and it appears their closest relatives may be the crustacean instead.
The appendages on the abdomen are extremely reduced, restricted to the external genitalia and sometimes a pair of sensory cerci on the last segment.

Bitsch, J. The hexapod appendage: Basic structure, development and origin.
The position of Diplura in the hexapods is unclear.
The most distinctive feature of the hexapods is the reduction in walking appendages to six, with three body segments consolidating to form the thorax, which provides much of the locomotory ability of the animals.

 Hexapod-Control Software (tkhex): User's Manual
This is the most primitive ( and most dangerous) way to describe the hexapod.
The hexapod position can be described using several different coordinate systems.
This is the most intuitive (though not the most convenient) way to describe the hexapod.

 Hexapod Software Model
The solid model information is complete; the model can be viewed from any position at any range.
The mechanism can behave in unexpected ways, as is shown for example by the calibration coefficient data, some of which looks simply wrong until one considers the kinematics carefully.
Though the hexapod mechanism is kinematically non-linear, the response to small parameter changes when static is linear.

The above comparision clearly shows the advantages of the low-inertia hexapod approach over a classical serial kinimatics system.
Up to 5 moving cables cause friction and cable management problems.

 LME Hexapod Machine
The hexapod mechanism is a variable triangulated frame which controls the position of a platform with six degrees of freedom.
I developed some ideas about this from first principles ten years ago, and then discovered that they were already known and were being explored by a few forward looking machine tool manufacturers.
The design has evolved over the past year to provide optimised solutions to the different technical requirements and problems.

 Technic/Hexapod based on Cybermaster
The program above only supports walking straight ahead, though, as there was no more memory avaliable for anything else.
The hexapod is physically capable of walking both forward and backward, in addition to turing either ways.
This is a very simple structure consisting of a 17×5 rectangle made up of two layers of standard beams.

 MHEX the hexapod robot
At the moment this system isn't functional because I haven't had time to implement anything but there will be more to come of this.
Just thought I should add the correct link to my new hexapod project site since the old link was dead.
This is not a simple question and depends on many factors.

 Imagination Engines, Inc., Inc....the future of all technology ...the future of mind
With absolutely no human mentoring, an 18 degree of freedom hexapod robot, developed its own behavioral repertoire with absolutely no human inputs.
In other words, the robot developed its own strategies for forward, backward, right turn, left turn, right shuffle, and left shuffle movement.
The Air Force Research Laboratory has awarded IEI a Phase II SBIR entitled "Creative Robots to Defeat Deeply Buried Targets." This will be a $750K contract to be conducted over a 24 month period.

This is the most sophisticated 3-DOF symmetrical hexapod control available anywhere.
We are asking for feedback on a new product, a totally artistic 12 servo hexapod called the H2 Dragon.
Easily control the body height, leg lift, speed and direction of walking with 8 different gaits!

 Frank Scott's Hexapod Robots
This was my third and current working hexapod.
This was my first working hexapod (Early photos, shown minus electronics).
The body of the robot comprises two end frames and an intermediate stiffening frame linked by four longitudinal spars.

 Hexapod Robot
This project used 12 oServo Objects for controlling the 12 servos on a Lynxmotion.
Power from the Battery was provided through the 40-Pin cable instead of normal the 2-Pin battery connector just to keep it clean looking.
The OOPic was conveniently the same width as the top of the Hexapod.

The next drawing shows how the drive shafts and motors are placed.
The hexapod's width is largely determined by locating the ends of each swing shaft in the end holes of 8-unit beams.
With this width, the swing motors are easily coupled to the swing shafts by a meshed pair of 24-tooth gears.
