An Android Brain for your Bot

The Objective - When your Bot has outgrown your Arduino, it wants to talk, an urge to communicate and Network(Social). A larger brain over the smaller control system is the need. Then a Networked Drove of Bots ! is possible.

Hobby DIY Electronics - Do it Yourself, The World Over.

Use the Arduino for emulating the role of the Spine and an Android System for the Big Networked brain. You can hack an Economy Android Phone to make your Robot an Einstein.

Now for Simulating the Soul, which even the most Advanced Robotic Scientist is unaware of; All you need is Cloud.

An Android Brain for your Bot

How to do that

We have to try create some Robots which are Non-Motor based, Soundless, No Rotary action. Minimum Metal Used, Silicone and Epoxy based parts. They will have 3G and Wi-Fi integrated and the Soul, the Intellect and the Instincts can be upgraded In-system online. The Cloud will be God.

Why the need

The Robot in Literature - Coppélia

Coppélia concerns an inventor, Dr Coppelius, who has made a life-size dancing doll. It is so lifelike that Franz, a village swain, becomes infatuated with it and sets aside his true heart's desire, Swanhilde.

She shows him his folly by dressing as the doll, pretending to make it come to life and ultimately saving him from an untimely end at the hands of the inventor.

The Truth - Swanhilde and her friends find themselves in a large room filled with people. However, the occupants aren't moving. The girls discover that, rather than people, these are life-size mechanical dolls. They quickly wind them up and watch them move. Swanhilde also finds Coppélia behind a curtain and discovers that she, too, is a doll.

The sad part of this Opera and The Nutcracker is that Inventors of Bots are shown as Evil Scientists. We have to clear the stigma by making a Giant King Kong Bot.

Reliable Robust Electronic Products

Use a Servo Stabilizer or CVT Constant Voltage Transformer or at least an Isolation Transformer. The First Defense form HV Surges, Spikes.

High Voltage Polyester & Polypropylene Metallized Capacitors in Stepdown Supplies should be Fire Retardant & Self Healing with a MOV too.

EE Design Library - Electronic Product Design Resource

Tropicalized means immunity or resistance of an equipment in conditions of varied Temperature, RH, Insects, Fungus, Brine, small life form.

Reliable Robust Electronic Products

Reliability by Simplicity

Vital controls should be Simple Electromechanical. Supervisory and Fine Automatic controls are in Embedded Computing. Mechanical Overrides!

<< More Reliable - Mechanical, Electrical, Analog, Digital, Embedded System (Firmware), Computing System (OS+Software) - Less Reliable >>

For a given quality level, more the components or parameters, may reduce reliability. Simpler the solution, more reliable it could be.

A Product's Life

If a product gives three years life with minimum service support it can save itself from building a bad reputation. six years will establish the brand on a long term basis, twelve years of product life you will have the user of the product selling for you.

Connectors and Interconnects

"Never Mix Electrical and Mechanical Connections" (probably from tektronix) this is a rule, more so for power connectors. Strain relief prevents mechanical stress from reaching the connector joints/spring metal. The wire terminations are also cushioned by strain relief.

The PCB and Product Engineering should ensure that the mechanical stress or load is not a job/function/role of the connector. At higher currents a small contact resistance can generate a lot of heat, worsening the contact further, similar to thermal runaway of Power Transistors.

EDA and Product Design Ideas

Product Design Optimization - Some Ideas of mine that are decades old , related to EDA and Product Design.

Make Practical (it works), Affordable, Usable (ergonomics), Safe, Reliable (robust), Durable and Consistent, Maintainable (means servicing) Products.

Dust and Contamination in Connectors

Once i opened a RF Millivolt Meter of Marconi Instruments. It did not have a spec of dust inside, not even one micron size of dust particle.

Connectors exposed to Environment should not only be Corrosion resistant but also Dust, Grime & Insect Proof! Dummy Covers on exposed units.

Air Vents, Fans & Unused Slots in Modular Instruments. Missing Fasteners in cabinets, gaps in panel components collect Dust & Insects inside

Dust + Moisture + Smoke + Pollutants = Conductive Grime Deposits on PCB, Parts & in-between the IC pins. Can Simulation include this aspect.

Virtual Environmental Testing a part of simulation and EDA, just like Mechanical Modelling and Studying Thermal Gradients on PCB.

AI Dodo with a Wikipedia Brain

Wikipedia Search Results combined with an AI Query and Data-mining Engine integrated with a High Quality Text-to-Speech; can help people hear Answers to Questions they ask. Optional pictures and video on a concealed LCD Screen, Packed into a Feather Bag called "Dolly the Know-all Dodo". A witty, impertinent, extra-smart Bird-Bot. (2009 - Ideas of delabs)

AI Dodo with a Wikipedia Brain

Idea from Polly -

Make a AI Robot in the form of a Cartoon Parakeet. Something like polly the techno parrot below. When you ask a question or a unique term like "Solar Energy" or "Vitamin C" it can use its AI - Artificial Intelligence to read out a Wikipedia Page and if not Satisfied browse the web internally and suggest alternative pages to read out. It can have a Dockable Tablet Interface too for Visualizing its AI and Articles.

Who made Polly  Shown on the right in CrossSection - Rob and Roberta Radtek

 "Direct from the Institute of Robotic Technology comes this amazing interactive robot pet-- POLLY THE TEKNO PARROT! Polly talks with people he senses around him just like a real parrot. Polly's electronic cuircuits can detect motion, sound, light and even touch. He will snore off to sleep at night and wake up in the morning. If you pet him, he will "coo" and move his wings. "

These are some sites that help you read out wikipedia.

Pediaphon App in the Android Market!MP3 files, play lists and podcast automatically generated from Wikipedia!  Let your computer read out the Wikipedia for you!

"Learning during jogging and driving! E-learning and m-learning with MP3 players and mobile phones! A podcast and a winamp play list will be generated too."

Wiki Out Loud: Wikipedia Entries on Audio - "A few nights ago I was at the office and the ol' brain was fried. I decide to take a couple of hours "off" and record some Wikipedia entries on audio."

See the Screens above using a Dynamic Active Interface that means the Interface Real Estate can be very Small like a Handheld or Smartphone.

Analog Music and Sound Effect Synthesizer

This experiment was done as i found that the Remote Controls and Mobile Phones in the Nineties and Early 2000 were difficult and stressful for me to use. This made me think of a Interface without menus but wizard like using a small but interactive interface area.

Tablets Slates to rule

Tablets and Slates based on OpenSource OS. Even OpenHardware Tablets. This is a collage of various blurbs of mine in my other pages.

Ultra-Mobile PC - UMPC

Tablets Slates to rule

Why Tablets ?
  1. People want computing to be Personal and Portable and hassle free. With less Maintenance Tasks.
  2. Low Power or Green is the order of the Age, Fuel and Energy is not as easy, expensive and depleting.
  3. Low Carbon Footprint, The global carbon footprint of making, selling and scrapping tablets is low.
  4. The Technologies have evolved in Flash, Battery, CPU, OS, GUI, LCD, SMT and most Electronic Parts.
  5. Online - Web Computing and Cloud Computing offers Safer Storage and Powerful Web Applications.
Most Important Specs. - Low Power, Wireless, Portable, Safe, Simple. The Browser is the Most and Only Important part of this Computer.

EDA and Product Design Ideas

I saw devices that are like Tablets. Handhelds, Nettops, Smart TV Computers. Low Power and enable to use the Internet on TV or any Display Device. Android is a nice Gadget OS, customise it to make your own device.

Desktop Power Supply Immunity

Make the desktop architecture like laptop with regards to Power Electronics. I think now RAM's consume lower power. So every Desktop can come with a Li-ion Backpack based on some standard. 10Ahr 12V Rechargeable Battery. The entire Motherboard works on the 12V DC supply that uses Float Charging from mains.

Power Electronics & Solar Energy

The supply to computer is always derived from battery, the battery being constantly replenished. The charger also supplies power to computer board over the battery itself. Many lighting/inverter systems use this. The SMPS now is only a intelligent charger. Other voltage levels with DC/DC converters from that 12V.

Desktop Power Supply Immunity

Advantage -

1 - A user can easily upgrade the 12 V bus, another 12 V battery with smart charger; gives a boost of backup time. Probably intelligent batteries can come with built in float chargers, so that they can they can be bussed to form a 12v Tiny power grid for home which includes solar cells.

2 - When just the backpack is used, power fails. Harddisk, Monitor etc. sent to standby, low power mode. CPU then goes to quiescent state. The RAM keeps all data intact but goes to a low power mode. Alternatively quickly write a RAM image on a Flash Layer Built over RAM.

This makes the PC Impervious to Power Supply or UPS or other problems. Moves the desktop system to a 12 V standard. Drives desktop PC development to more Power Efficient designs.

Switching Supplies and SMPS

Easy integration into automobiles, bus, etc which have DC grid. Remote areas where no power is there. This will ensure desktops have a role in the future.

The charger SMPS has 1A charging current for Battery and 3A max for Computer. Total 4A max. A SuperCap can be added parallel to the Battery for Extra Inertia.

When power fails, in few seconds the system goes to standby. No program need to be closed. When power is restored they system comes up with windows and programs in the same positions of the last frozen state.

When a UPS is used, the system does not go down at all. The UPS just consists of a 10A Charger and a 12V 20AHr Battery. If the house has a 24V DC bus which is battery supported too. Then this can be used. As 24V is being developed as a new standard for internal power distribution. EMerge Alliance. The PCs also can move to this manageable and safe standard for homes.
