Upgraded Ensenso 3D camera series now available at IDS
 

Resolution and accuracy have almost doubled, the price has remained the same – those who choose 3D cameras from the Ensenso N series can now benefit from more advanced models. The new stereo vision cameras (N31, N36, N41, N46) can now be purchased from IDS Imaging Development Systems.

The Ensenso N 3D cameras have a compact housing (made of aluminium or plastic composite, depending on the model) with an integrated pattern projector. They are suitable for capturing both static and moving objects. The integrated projector projects a high-contrast texture onto the objects in question. A pattern mask with a random dot pattern complements non-existing or only weakly visible surface structures. This allows the cameras to deliver detailed 3D point clouds even in difficult lighting conditions.

With the Ensenso models N31, N36, N41 and N46, IDS is now launching the next generation of the previously available N30, N35, N40 and N45. Visually, the cameras do not differ from their predecessors. They do, however, use a new sensor from Sony, the IMX392. This results in a higher resolution (2.3 MP instead of 1.3 MP). All cameras are pre-calibrated and therefore easy to set up. The Ensenso selector on the IDS website helps to choose the right model.

Whether firmly installed or in mobile use on a robot arm: with Ensenso N, users opt for a 3D camera series that provides reliable 3D information for a wide range of applications. The cameras prove their worth in single item picking, for example, support remote-controlled industrial robots, are used in logistics and even help to automate high-volume laundries. IDS provides more in-depth insights into the versatile application possibilities with case studies on the company website.

Rico is a smarthome security device that uses your old smartphone as its brain and eyes. We took away the clutter of heavy and expensive home security hardware and replaced them with an old smartphone. All you need to do is install an App into your old smartphone, insert it into Rico, turn it on, and your smarthome security companion is ready.

Rico has just launched on Kickstarter

Kallidil Kalidasan, the CEO of MindHelix, Inc which created Rico says, “Smartphones are really powerful devices with HD cameras, microphones, 3G and WiFi connectivity and a powerful processor. Rico takes these capabilities and uses them to transform your home into a smarter, secure home at an affordable price point.”

Users connect with their Rico through the Rico App which will be available across all major smartphone platforms. Rico comes equipped with photo electric sensors that detect the slightest changes in your home like temperature, humidity, motion, carbon monoxide, smoke, natural gas, noise levels etc. It will immediately alert you when something goes wrong and you can even watch live video of your living room with Rico App. Rico also comes with smart power sockets which can control your appliances using the Rico App from anywhere.

Whilst Rico is an effective solution to home security, Kali points out that the product is trying to solve a much bigger problem. “We love how cute Rico is. But the reality of how many smartphones are wasted is not so cute. So we decided that this would be a focus for us when we began the project. It turns out that we have created not just a viable alternative use for your old smartphone, but an industry-disrupting product. Because of this, we truly believe it is going to take the world by storm.”

He is right. For the average consumer, the shelf-life of a smartphone is 24 months. According to IDC, of the over 280 million smartphones that were sold last year, many will be replaced without being recycled. These phones are toxic to the environment, polluting the air and contaminating soil and water with metals and plastics. What’s worse is that over 90% of these will be in perfect working order.

With Rico, MindHelix aims to disrupt the smart-home market and then encourage us to rethink how we consume electronics. The company plans to open up developer APIs for Rico, allowing developers around the world to create a community and help Rico grow. Kali says “We’ve developed working prototypes of Rico and we need your help to bring Rico to market. We want to solve the problem of used smartphones creating a huge environmental impact. Rico helps consumers repurpose them for something as cool as a smart home solution”.

Rico is a product from Mindhelix, Inc a Bay Area based startup which was part of the batch 3 at the Alchemist Accelerator program.

Rico is now raising $100,000 on Kickstarter and has already chalked up 30% of its target in the first week. Kickstarter page here : http://kck.st/1pmEqzN

Interesting designs for Rescue Robots – Part 2

Professor Dr. Satoshi Tadokoro from the Tohoku University  presents his ASC. ASC is an search camera for usage in emergency situations and stands for Active Scope Camera. In basic it is a flexible endoscope which is able to move by it self. With the help of vibrating inclined cilia this endoscope can like a caterpillar crawl into smallest voids (>30 mm). Its maximum speed is 47 mm/s and the operating range is 8 m. This allows rescue workers to search in rubbles for victims or checking the structure of it.

The following video shows Professor Dr. Satoshi Tadokoro at the Tokyo International Fire and Safety Exhibition 2008 presenting the ASC.

During the Collapse of the Historical Archive of the City of Cologne (March 2009),  Professor Dr. Satoshi Tadokoro, Professor Dr. Robin R. Murphy (Texas A&M University), Clint Arnett (Project Coordinator for Urban Search and Rescue in TEEX), members of the Fraunhofer Institute for Intelligent Analysis and Information Systems (IAIS) were trying to support the local fire department. Therefore I was able to test the ASC which was in use during this disaster.

The ASC performs extremely well. It can crawl in a reasonable speed into the rubble and is (after a little training) easy to use. But the biggest problem is the user interface. The ASC camera system does not compensated tilting or turning if the „robot“ does flip/turn over, which happens quite often. Hence, it is hard for the Operator to keep track of the orientation. In addition the opening angle of the camera is extreme small, which does even more handicap the situational awareness.
