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.

Test Measurement and Test jigs

Test Tools are needed for Troubleshooting and Repairing Electronic Gadgets, Equipment, Electrical Panels and Machines. Precision Instruments are required for calibration of field and machine control electronics. These are also required by the R&D engineer for design and development of new products and trying out new concepts.

Test and Measurement

Test Measurement and Test jigs - delabs

In Production testing, Production Engineering, Quality Assurance QA-QC etc. You need to build Test Jigs, Configure Automated Testing depending on the size of project or budget allocated; yet it has to be made flexible, scalable and modular. These require instruments or blocks that can be adapted and reconfigured or even interface with a computing network for automated testing, reporting and analysis.

Special Electronics come with every tool or gadget these days, A Slide calipers has a LCD display, Digital Readouts on mechanical instruments can help measure even sub-microns easily. Analytical and Chemical Instrumentation is another specialized niche. Then we have medical instrumentation which is more demanding in quality and requires sensors that are small, very sensitive and safe.
Instrumentation goes into all these and beyond. The day we find water on mars, It is only because of a precision instrument at the helm of things.

These are basic measuring circuits you can build for your home lab. I have documented a lab DMM i had built for my use many years ago. the circuits may have errors, build it only if you understand.

Interactive Examples and Exercises - Jim Svoboda

James A. Svoboda - ECE Department, Clarkson University has created numerous interactive examples throughout the textbook - Introduction to Electric Circuits. Interactive Examples made of Java Applets.

Interactive Examples and Exercises - Jim Svoboda

The Interactive Exercise shown here considers a similar, but different, circuit. Like the Interactive Example, the Interactive Exercise poses a problem, then accepts and checks the user's answer. Student learning is further supported by extensive help, in the form of worked example problems, available from within the Interactive Exercise using the “Worked Example” button.

Interactive Examples and Exercises - Jim Svoboda

Circuit Design Lab

The Circuit Design Lab consists of several Java applets, each providing an opportunity to experiment with the design of a particular circuit:

Variations of this problem are obtained using the “New Problem” button. We can peek at the answer using the “Show Answer” button. The Interactive Example and Exercises provide hundreds of addition practice problems with countless variations, all with answers that are checked immediately by the computer.
