Science Nation - Printable Robots Designed to be Consumer-friendly, Inexpensive

Posted by Andreas Christodoulou

Description : 

Hello guys. Today we'll present to you an interesting project funded by the National Science Foundation's (NSF) Expeditions in Computing Program. This project envisions a future in which 3-D robotic systems can be produced and designed using 2-D desktop technology fabrication methods. If this feat is achieved, it would be possible for the average person to design, customize and print a specialized robot in a matter of hours. 

Currently, it takes years and many resources to produce, program and design a functioning robot. This project would completely automate the process, from sketches on-demand, anywhere, and with the skill of a team of professional engineers, leading to potential transformations in advanced manufacturing. 

"This research revolutionizes the design and manufacturing of robots, with a profound potential impact on society," says Ralph Wachter, a program director in the NSF Directorate for Computer and Information Science and Engineering. "It would remove barriers to manufacturing robots, making it possible for average citizens to customize and manufacture their own robots to meet their needs. This opens the door to great possibilities."

"This research envisions a whole new way of thinking about the design and manufacturing of robots, and could have a profound impact on society," says MIT Professor Daniela Rus, project leader and director of the Computer Science and Artificial Intelligence Lab (CSAIL). "We believe that it has the potential to transform manufacturing and to democratize access to robots."

The Computer Science and Artificial Intelligence Laboratory, known as CSAIL, is the largest interdepartmental laboratory at MIT and one of the world's most important centers of computer science and information technology research. The lab has played a major role in the technology revolution of the past 50 years. Currently, CSAIL is focused on conducting groundbreaking research in artificial intelligence, computer systems, and the theory of computation, while also tackling pressing societal challenges such as education, health care, manufacturing and transportation.

"Our goal is to develop technology that enables anyone to manufacture their own customized robot. This is truly a game changer," adds engineering professor Vijay Kumar, who is leading the team from the University of Pennsylvania. "It could allow for the rapid design and manufacture of customized goods, and change the way we teach science and technology in high schools."

Direct Differences Between Inkjet and Laser Printers

Posted by Andreas Christodoulou

Torn Between an Inkjet and a Laser Printer? 

Can’t decide between an inkjet and a laser printer? You’re not alone. Most, if not all, consumers wanting to buy a new printer have faced this dilemma. 

Often, budget constraints force a consumer to get the cheaper option, not knowing the better option to buy to meet their printing needs. Budget may play a big role in your choice of printer, but there are a variety of factors to consider, namely which one will work best for your projects.

Printing Volume 

One of the first things to consider when looking for a new printer is to know where you’re going to use it. Will it be used at home or at the office? Given this factor, a family, who occasionally uses a printer, will benefit most from an inkjet. On the other hand, you’ll most probably need a laser printer if you expect to print documents, photos, and other materials in high volumes. 

Size 

Another difference between inkjets and laser printers are their size. Generally, the latter tends to be larger in size. Hence, this is another reason homeowners, especially those with limited space, are best advised to purchase an inkjet printer. If space is not an issue, you can consider printers with laser technology. 

Speed 

Laser printers are best suited for those who expect high volumes of printing largely because of their print speed. Quality laser printers have faster printing capabilities and can print at a speed of 10-15 pages per minute - inkjet printers are not as fast and generally have a lower printing speed. Laser printers are then best for homes or businesses which require hundreds of pages printed at a time. 

Technology and Supplies 

Inkjet printers make use of simpler technology and parts compared to laser printers. As the name implies, ink is used for inkjet printers, while laser printers use toner. Unlike ink, toner is made, and needs to be used for, a specific kind of printer; meaning you can’t mix and match toner cartridges. 

Resolution 

Due to the difference in technology, the print quality and resolution vary between laser and inkjets. Laser technology in printers gives it a higher resolution and print quality and is best for printing in colour. Inkjets are better for printing word documents and the odd photograph. 

Paper 

To achieve the best resolution and printing outcomes, the right type of paper should also be considered. Remember, a laser printer works well with almost any kind of paper. On the other hand, inkjets work best with specialty paper designed for inkjet printers - otherwise, there’s a good chance you’ll end up with some fuzzy photos. 

Costs 

The laser printer might appear to cost more than an inkjet; however, you should always remember that your purchase should not be based on the initial costs alone. The cost of maintenance, if needed, ink, toner and paper should all be taken into consideration. 

Given the above list, the best thing to do when deciding what printer to buy, is first think about what you will mainly be using it for. That way, you won’t end up buying an inkjet when it’s a laser printer you should really be getting, and vice versa.
