  • Drones do donuts, figure-eights around obstacles
    a high level of guarantees that the software will work even in the face of uncertainties with both the surroundings and the hardware itself The algorithm can easily be extended to drones of different sizes and payloads as well as ground vehicles and walking robots As for the environment imagine the drone choosing between making a forceful roll maneuver that will avoid a tree by a large margin versus flying straight and avoiding a tree by a small amount A traditional approach might prefer the first since avoiding obstacles by a significant amount seems safer Majumdar says But a move like that actually may be riskier because it s more susceptible to wind gusts Our method makes these decisions in real time which is critical if we want drones to move out of the labs and operate in real world scenarios A clear path to avoiding obstacles CSAIL researchers have been working on this problem for many years Professor Nick Roy has been honing algorithms for drones to develop maps and avoid objects in real time in November a team led by PhD student Andrew Barry published a video demonstrating algorithms that allow a drone to dart between trees at speeds of 30 miles per hour While these two drones cannot travel quite as fast as Barry s their maneuvers are generally more complex meaning that they can navigate in smaller denser environments Enabling dynamic flight of small off the shelf quadcopters is a marvelous achievement and one that has many potential applications Yu says With additional development I can imagine these machines being used as probes in hard to reach places from exploring caves to doing search and rescue in collapsed buildings Landry who now works for 3D Robotics in California is hopeful that other academics will build on and refine the researchers work which is all open source and available on github A big challenge for industry is determining which technologies are actually mature enough to use in real products Landry says The best way to do that is to conduct experiments that focus on all of the corner cases and can demonstrate that algorithms like these will actually work 99 999 percent of the time Explore further Autonomy expert led team in developing self flying planes More information Aggressive Quadrotor Flight through Cluttered Environments Using Mixed Integer Programming groups csail mit edu robotics center public papers Landry15b pdf Funnel Libraries for Real Time Robust Feedback Motion Planning arxiv org abs 1601 04037 Provided by Massachusetts Institute of Technology 433 shares feedback to editors This story is republished courtesy of MIT News web mit edu newsoffice a popular site that covers news about MIT research innovation and teaching Tweet Favorites Email Print PDF Featured Last comments Popular Detection of gravitational waves would open new window on universe Feb 10 2016 58 Gravitational waves detected 100 years after Einstein s prediction Feb 11 2016 144 GPS tracking down to the centimeter Feb 11 2016 10 A metal that behaves

  • Engineers create artificial skin that can send pressure sensation to brain cell
    fingers of a model robotic hand Credit Bao Research Group Stanford University Finally the team had to prove that the electronic signal could be recognized by a biological neuron It did this by adapting a technique developed by Karl Deisseroth a fellow professor of bioengineering at Stanford who pioneered a field that combines genetics and optics called optogenetics Researchers bioengineer cells to make them sensitive to specific frequencies of light then use light pulses to switch cells or the processes being carried on inside them on and off For this experiment the team members engineered a line of neurons to simulate a portion of the human nervous system They translated the electronic pressure signals from the artificial skin into light pulses which activated the neurons proving that the artificial skin could generate a sensory output compatible with nerve cells Optogenetics was only used as an experimental proof of concept Bao said and other methods of stimulating nerves are likely to be used in real prosthetic devices Bao s team has already worked with Bianxiao Cui an associate professor of chemistry at Stanford to show that direct stimulation of neurons with electrical pulses is possible Bao s team envisions developing different sensors to replicate for instance the ability to distinguish corduroy versus silk or a cold glass of water from a hot cup of coffee This will take time There are six types of biological sensing mechanisms in the human hand and the experiment described in Science reports success in just one of them Stretchable skin with flexible artificial mechanoreceptors Credit Bao Research Group Stanford University But the current two ply approach means the team can add sensations as it develops new mechanisms And the inkjet printing fabrication process suggests how a network of sensors could be deposited over a flexible layer and folded over a prosthetic hand We have a lot of work to take this from experimental to practical applications Bao said But after spending many years in this work I now see a clear path where we can take our artificial skin Explore further New stretchable solar cells will power artificial electronic super skin More information A skin inspired organic digital mechanoreceptor by B C K Tee et al www sciencemag org lookup doi 10 1126 science aaa9306 Journal reference Science Provided by Stanford University 10464 shares feedback to editors Tweet Favorites Email Print PDF Featured Last comments Popular Detection of gravitational waves would open new window on universe Feb 10 2016 58 Gravitational waves detected 100 years after Einstein s prediction Feb 11 2016 144 GPS tracking down to the centimeter Feb 11 2016 10 A metal that behaves like water Feb 11 2016 2 Physicists create first photonic Maxwell s demon 14 hours ago 3 more Phys org on facebook Relevant PhysicsForums posts Zeno s arrow paradox 1 hour ago Arrows vs plate armor 1 hour ago Wave impedance of free space 1 hour ago Work done on a stationary bycicle 1 hour ago Brainstorming Large
