From Virtual Anthropomorphic Robots to Androids

Robotics is the Magnum Opus of Engineering, It combines Electronics, Mechanical, Computing and also the toughest science know to mankind.... Wireless Networking!

Ethernet Networking itself is complex, A self healing, hack proof and plug-play Wireless Router has to be the first step to make safe robots.

From Virtual Anthropomorphic Robots to Androids

Just imagine a Wireless Router or even a Internet Router as easy to tune as a FM radio, no entering numbers, no admin with browser. Just keep it in a room and all gadgets and computers form a fuzzy network, all by themselves. The very idea of technology is to make things simple, cost-effective and efficient.

The real need of robots now is to avoid Humans in Hazardous Environment. Right from Outer Space to working in a Plant with Toxic Chemical Gases, Even machinery and equipment that injures the limbs or damages the eyes.

Virtual Robotics Lab - building a mobile robot

Virtualization in Robotics -

If workers can wear a coat of sensors with force feedback actuators, they can control a semi-automatic robot in Real-Time. This enables a worker to navigate a robot into a hazardous environment, perform an upgrade or make repairs. An accident or mishap will damage the robot and it can be easily rebuilt or maintained.

The robot is automatic and will have reflexes defined by software. The wireless networking will connect the Robot mechanically to a human in a safe enclosure. This makes the Worker present virtually inside the Robot, because he is connected by optical, aural and mechanical-muscle feedback-sensors. This will create Virtual Anthropomorphic Robots for Industrial use and may help to finally develop Fuzzy Robots or Androids, which is still in the relm of science fiction.

K-12 Experiments in Robotic Software
The ROVer Ranch is an interactive, Web-based robotics workshop for assembling the hardware and instructions for a software robot to perform a mission in a virtual environment.

Animatronics is a multi-disciplinary field which integrates anatomy, robots, mechatronics, and puppetry resulting in lifelike animation. Animatronic figures are often powered by pneumatics, hydraulics, and/or by electrical means, and can be implemented using both computer control and human control, including teleoperation.

VirtualRobot is a freeware software suite
Its beginning, on 1998, was motivated by the need of a remote graphical application for programming, monitoring and simulating multi-robot cells on the control system GENERIS (Generalised Software Control System for Industrial Robots) developed by European Commission Joint Research Centre.

Vicacopter - Open Flight Robotics

Source code and many notes used in Vicacopter, the 1st English language source code for a fully functional helicopter autopilot.

Vicacopter - Open Flight Robotics

Vicacopter uses a ground computer for flight control. An 8 bit airborne microcontroller handles rate damping, PWM, & sensor capturing. The ground computer handles navigation & provides a simple instrument panel. This was the cheapest & most flexible way to fly. The system can be converted to a completely airborne autopilot very simply.

Vicacopter - Open Flight Robotics

Some Features
  • Automated landing & takeoff
  • Sonar position sensing for indoor flight
  • GPS position sensing for outdoor flight
  • Ground station instrument panel
  • Untethered communication from pilot to ground station
  • Curved or linear paths

The Tri-Roter one used 3 gyros for short term rotation sensing, 2 accelerometers for long term tilt sensing, 3 magnetometers for long term heading sensing, a high quality GPS module for horizontal position, a barometer for altitude sensing. A 3rd accelerometer was too sensitive to vibration & altitude changes to be any good. Because of the long term sensors & the very stable gyros, the orientation was always pretty accurate & didn't drift.

The Handy Board - The Cricket Robotics Controller

The Handy Board is a 6811-based microcontroller system that lets you build mobile robots for educational, hobbyist, and industrial purposes. People use the Handy Board to run robot design courses and competitions at the university and high school level, build robots for fun, and control industrial devices.

The Handy Board - The Cricket Robotics Controller
  • can control two motors and can accept two sensors, plus it has an expansion port for additional devices.
  • has a built-in infra-red port, so Crickets can communicate with each other.
  • is powered by four AA batteries.
  • is programmed using "Cricket Logo," a version of the powerful, yet easy-to-learn Logo language.

The Handy Cricket is a tiny robotics controller is much smaller than the Handy Board, weighing only a few ounces.

You can control motors and lights with the Cricket. The Cricket can receive information from sensors, like touch sensors and light sensors. Crickets can “talk” to each other, sending messages with infrared (IR) light. People have used Crickets to build little robots, animated rocking horses, automatic gift boxes, and other personal animated toys.

People have used Crickets to collect a bunch of temperature readings and look at them later. Crickets were developed at a major research university and now they are available to the public.

Bionics - Nature Innovates Technology Follows

Molecubes Bionic Learning Network Festo - "Molecubes - an attractive programmable robotics system Molecubes could play a significant role in technical training in the near future. These cubes, fitted with computer chips, can be successively attached to each other."

Festo Bionic Learning Network
  Molecubes Bionic Learning Network Festo
"Bionic design principles serve as the basis for the development of new gripper technology for flexible adaptive grasping in the mechanical handling industry..."

Here Festo is helping students of Robotics and Automation learn from nature's intricate and sophisticated Nueromuscular Systems. I am using the word Nueromuscular in a different way, here it means Wires (Nerves), Control System (Brain, Spinal cord), Solenoids & Valves (Muscular System).

These Bionic Systems can also be used the other way around, they can be designed for Reinforcing/Replacing Weak or Lost Limbs. Even a person with a handicap, can do most tasks on his own, aided by the Bionic Appendages.

Study These Resources to understand Bionics which is closely related to Robotics and Automation.

Build Electronic Circuits Like a Pro

If you want to build electronic circuits, you need to connect the components of your circuit somehow. If you expect to make your circuit work more than just a few times, you need a solid way of connecting them. You need to create a printed circuit board (PCB).

"I started playing with electronics as a hobby when I was 14. Since then I have finished a Master's degree and founded two electronic design companies."

The radar sensor uses a Ultra-Wideband (UWB) chip from Novelda. It sends out electromagnetic pulses and analyzes the pulses that are reflected back. In the video above, a part of the electromagnetic pulse will be reflected back when it hits the wall and a part of it penetrates the wall and is reflected from the cabinet behind the wall.

Dallas Personal Robotics Group - DPRG

"Articles, Photo Gallery, Projects, RoboLinks, Tutorials, One of the advantages of belonging to a group like the DPRG is that you can almost always find someone who has tried to solve the same problem you're working on and is will to share their solution. In that spirit, DPRG members sometimes write up solutions to common problems faced by robot builders."IR Proximity Detector - DPRG
