Flying Insect like robot - RoboBee by Harvard University

As engineers and scientists collaborate to design ever more sophisticated aerial robots, nature has been a constant source of inspiration, with flying insects, birds and mammals providing valuable insights on how to get airborne.
Recently, a robotics team at Harvard University developed a method that would allow their insect-size flying robot — dubbed "RoboBee" — to conserve energy midflight, much as bees, bats and birds do.
By attaching a shock-absorbing mount and a patch that conducts electricity, the researchers were able to direct the tiny robot to perch on a variety of surfaces and then take off again. When activated, the electrical charge held RoboBee in place, much like how a balloon will stick to a wall after you rub it against a wool sweater. Terminating the charge enabled the robot to detach from the surface and fly away.
RoboBee is about the size and weight of an actual bee — about 0.004 ounces (100 milligrams) and 0.8 inches (20 millimeters) tall, with a wingspan of…

Advantages of virtual reality in medicine

Virtual reality is used in many areas of healthcare which range from diagnosis, treatment, e.g. surgery, rehab and counselling. It is also used to train the next generation of doctors, paramedics and other medical personnel and has shown a range of benefits from doing so.So what are the advantages of virtual reality in healthcare? There are several which are related to medical/surgical training, preventative medicine, counselling and architectural design of new hospitals and many more.
Let’s start with virtual reality as a means of training healthcare professionals. It is used in medical schools and other similar settings as a means of education and instruction. It enables medical students to acquire knowledge and understanding about the human body by means of interaction within a virtual environment. Virtual Reality Dentistry But virtual reality isn’t only confined to medical schools. Dentistry is another area in which it plays a part. For example, there is a system known as ‘HapTEL’ wh…

Virtual Reality : Early Year

Let’s start with a quick primer on the history of VR.  VR was created in 1965 by Ivan Sutherland – he created the “Ultimate Display”, a device that could overlay wireframe interiors onto a room.  The military was researching and investing in VR’s potential for flight simulation and training.

The VR industry continued to develop over the next couple of decades, but appeal was limited to only the most ambitious engineers and early adapters due to the cost of components, and the computers that powered them.  PALMER LUCKEY AND OCULUS RIFT CHANGE THE GAME Fast-forward 40 years and Palmer Luckey (the inventor of the Oculus Rift) created his first VR prototype at age 18 in his parents basement. He  developed the product that would come to be known as the Oculus Rift. The announcement of the Oculus was followed closely by tech insiders, developers, and early adopters, all of whom had been chomping at the bit to experience this new frontier in VR development. It wasn’t long before heavy-weights l…

Augmented Reality Used for Medical Products

Ivan Sutherland introduced his ultimate display in 1965, he thought about a world existing of real and virtual objects which is presented to the observer through his natural perspective or through his eyes.

Nowadays, Augmented Reality solutions still use hardware interfaces that do not follow most natural form of immersion, e.g. augmented camera views of tablet PCs and any smartphones. In the last few years lot of head worn AR interfaces have been created and released.  One of them is SDKs which is related to head mounted displays which have inspired thousands of developers to create AR worlds for to enhance industrial tasks .Also they make cultural experiences more interactive, attractive and appealing.
It is very difficult to introduce these devices to the medical world, in particular to intraoperative tasks that require high quality standards.  This is certainly a commendable approach, which will happen once the benefit for patient treatment has been proven and usability has reached…
