Robot's Gentle Touch Aids Delicate Cancer Surgery - 0 views

  • Surgeons have developed new minimally invasive surgery (MIS) techniques and instruments so that procedures that would previously have required a large incision can now be performed through a tiny 10mm cut.
  • University of Western Ontario and Canadian Surgical Technologies and Advanced Robotics (CSTAR) in London, Ontario
  • The researchers used a torque sensor to measure the force of the palpations.

  • Using tactile MIS sensing instruments under robotic control reduces the maximum force applied to the tissue by over 35% compared to a human controlling the same instrument. Accuracy in detecting the tumours was also far greater with the robot - between 59 and 90% depending on the robot control method used for palpation.
  • If developed further, the authors suggest that this type of instrument would particularly benefit surgeons performing lung tumour resection, where tissue often shifts significantly.

Stay foundation Stuttgart - Stay Stiftung - 1 views

  •  
    What does the Stay Foundation do once the social enterprises have found each other? In the truest sense of the word development-aid.These local social enterprises lack the financial support to exploit their development potential. The team of the Stay Foundation in Stuttgart is sure that if funds are provided by industrial nations, which are then used for the expansion of existing social enterprises, it is development-aid on an equal footing. The challenge in Germany is therefore to attract companies and private individuals to invest in social enterprises in developing countries. In order to raise awareness of Africa and the local social enterprises which are active there, the team organises events for entrepreneurs, is present at events on the subject of Africa, informs private individuals about the foundation and its objectives, examines possibilities for funding and cooperation with the aim of supporting the remaining development in Africa.

Open Source 3-D Printed Nutating Mixer - Appropedia, the sustainability wiki - 0 views

  •  
    "As the open source development of additive manufacturing has led to low-cost desktop three-dimensional (3-D) printing, a number of scientists throughout the world have begun to share digital designs of free and open source scientific hardware. Open source scientific hardware enables custom experimentation, laboratory control, rapid upgrading, transparent maintenance, and lower costs in general. To aid in this trend, this study describes the development, design, assembly, and operation of a 3-D printable open source desktop nutating mixer, which provides a fixed 20° platform tilt angle for a gentle three-dimensional (gyrating) agitation of chemical or biological samples (e.g., DNA or blood samples) without foam formation. The custom components for the nutating mixer are designed using open source FreeCAD software to enable customization. All of the non-readily available components can be fabricated with a low-cost RepRap 3-D printer using an open source software tool chain from common thermoplastics. All of the designs are open sourced and can be configured to add more functionality to the equipment in the future. It is relatively easy to assemble and is accessible to both the science education of younger students as well as state-of-the-art research laboratories. Overall, the open source nutating mixer can be fabricated with US$37 in parts, which is 1/10th of the cost of proprietary nutating mixers with similar capabilities. The open source nature of the device allow it to be easily repaired or upgraded with digital files, as well as to accommodate custom sample sizes and mixing velocities with minimal additional costs."

Social Impact Network - 0 views

  •  
    The "Social Impact Network" approach will be a combination of a crowd based impact investment infrastructure, onboarded international aid organisation as stakeholders and local project coordinators for the implementation of impact projects in local communities in need. The platform will start with Photovoltaic projects in Lebanon, with UNDP Lebanon Country Office as first main stakeholder that reviews the PV projects & identifies project coordinators. This approach can also work to help implement the "Greens for Good" solution.

The Rise of the Service Robot - 2 views

  • Some experts believe that service robots will change the world the same way the personal computer did 30 years ago.
  • The field is relatively new, so the definition of “service robot” is still up for discussion, but it is generally considered to be a robot that is not installed in an industrial setting.
  • New sensors and processes that provide real-time environment monitoring in 3-D must not only prevent collisions during manipulation but also identify and learn new objects. The increasing use of service robots in everyday environments ultimately calls for new user interfaces that can take into account the full range of communications channels.

  • “The biggest challenge is to cope with the dynamic and unpredictable environment of service robots,” Fischer said. “Compared to industrial robots, the environment is totally undefined
