I posted several pictures of my completed humanoid MANaTRON, at the photos section in the Yahoo Toddler Robot group...

Look for the Mike G. Otis folder and HUMANOID. There are five pictures and a text image.

I've also created a MANaTRON web site...

This humanoid is a proof of concept. It's gone through many stages of development, some more technical, some less. I tried to simplify this version as much as possible, not only in terms of weight but operating technicality. I'd like to make a web site devoted to the complete speech system. It's nice to program the humanoid in other languages such as Chinese and Japanese. You never know when that will come in handy during an international trip.

Project MANaTRON is nearing completion. Here's the preliminary description of this humanoid robot:

Class: Walking Humanoid

Brains: Multiple

Motion: Head, arms, feet, legs, torso

Cost: $500

Servos: 6

Microcontrollers: multiple Basic Stamp 2

Speech: SPO256 Allophone Processor

Exoskeleton: Aluminum tin cans

Walking: Tilt and stride

Languages: Multilingual

Programming: PBASIC

Vision: IR detectors

Backpack: SSC controller

Meet MANaTRON - the most exciting, sophisticated and newest robot in the homebuilt Tron family! (other members include Zylatron, Son of Zylatron, Bugatron, and Automatron)

Built from 2002 to 2004, MANaTRON is the first family humanoid, with six degrees of freedom - enabling motions for arms, legs, feet, head, and torso.

For tilt and stride, this humanoid uses a Basic Stamp computer and parts from a Parallax Toddler kit. The key to its expanded mechanical motions is a miniature upper mobility core, created from four unionized servos mounted orthogonal to each other.

Expansion success is all about "center of gravity" and weight control. MANaTron sports chrome colors in a nearly weightless and highly durable outfit comprised of recycled aluminum sardine cans, nylon nuts & bolts, and phenolic washers.

Programming is with a Macintosh computer and PBASIC - an efficient language designed specifically for microcontroller applications. MANaTRON is completely self sufficient and autonomous.

Additional Basic Stamp 2 computers are distributed throughout the robots tin can exoskeleton, interfaced to a serial servo controller SSC for motion, and add-ons such as SPO256 alophone speech, infrared vision, tilt inclinometer, and expansion pcb's.

Prototyping was accomplished with two Parallax BOEs (Board of Education), and solderless breadboards purchased in Taiwan.

Power is derived from on-board 9-volt and AA batteries, distributed throughout, for weight distribution. A home- built inclinometer fine tunes walking across surfaces that are not level. The robot stands just over 14-inches tall, and would cost about $500 in parts to duplicate.

Bringing MANaTRON to life is a spectacular experience! Primary applications are education, fun, and hobby. He can do simple walk, dance, Chinese Tai Chi, and is multilingual as programmed. For more information:

Parallax has made it possible for me to continue work more rapidly on the 3D computer by supplying parts for expanding the number of spacial computers. You will remember this project was conceived with just two computers and a hardware interface. The interface design is now purely optical and lensing in nature, and "n" dimensional, and is leading to the addition of numerous computers located in n-space.

N-space makes it possible for all computers to simultaneously contribute to the core as light paths can become infinitely dense. The population density goes to infinity as the optical dimension increases. Over the last 2 years, the phase of the project was primarily mathematical, with work continuing to perfect the ultimate matrix equation.

I recently assembled two more computers and have these working and tested. The primary reason for developing the optical n-dimensional 3D computer is for use as a humanoid brain. (Current networked computers are far too slow for use as advanced robot brains.) I wish to give my personal thanks to Parallax company and Ken Gracey for their support and interest in this project. Their basic stamp computer is ideal for a number of robotic projects. Their web site is at http://www.parallaxinc.com/

Work is commencing on a new robotics lab, one that is expanded to support the vast amount of equipment necessary to create the latest biped humanoid. This new research laboratory will have additional facets such as an astronomical observatory, special storage buildings for cybernetic inventory, multifield parts (such as optics, mechanics, optoelectronics, magnetics, particle dynamics, electrical and electronic, etc.), vehicular garage, communications equipment, multiple security systems, scientific research library, computers and internet, and all the essentials for comfort. I've worked nearly a year on this project!

I finally got my robots.net log in to work again and found all the humanoid parts after returning from my trip. Over the next few weeks, my main project will be assembly of parts.

The Quad Servo Core is built. Now the task at hand is programming it. The dual bearing design and prototype on the Upper Body Torso Mobility Core was a great success. An assembly is now working and in progress. Several movies were made showing the primary unit walking. A static mount was invented to sustain the upper torso assembly during code development.

Humanoido Extensions: Worked progressed on the Upper Body Torso Mobility Core. It's now apparent that the omega plane will need bearings. I believe it's possible to fabricate a three dimensional cylindrical bearing to provide increased support and reduce upper body flexure. The rotation results in an eccentric, therefore cylinder placement requires attention. Tests show that certain plastics have very little friction when placed in plane to plane contact, not unlike a teflon surface bearing. This approach will be incorporated into initial designs.

You are politely requested to GOTO HERE and take a look at message #62. You'll see exactly what happens with a good robot and a very bad case of the ROBOTIC Dr. Jekyl - Mr. Hyde syndrome...

Sept. 1 - Sept. 7

Worked on designing a small operating system, called SMALL-WALK OS 1.0, which includes derivative code to achieve a series of fundamental walking motions. Introduced SMALL-WALK OS 1.0 as a new project.

Worked on the Exoskeleton Project. Completed two legs, and installed a head on Humanoido. Currently building arms. Moving placement of shoulders to compensate for head to shoulder displacements.

Worked on the Quad Servo Project and completed the design. Design/utilize brass mechanics mountings. Project moves to the assembly and testing phases.
