Maverick is a small uav made by Prioria, a company founded in 2003 by business and engineering graduates from the University of Florida. It is portable, very light and has most of the features a comme...

Underwater 3D mapping

  13 May 2011
We saw the need for good underwater robots during the Deepwater spill last summer. In such scenarios, a remote operator controls a robot equipped with a camera and means to build a 2D map of the envir...

Place recognition and localization with omnidirectional vision

  09 May 2011
Let’s say you just purchased a new service robot and you want it to be able to know its way in your apartment. The obvious thing to do would be to show it around, going from room to room saying ...

Stable visual navigation

  20 Apr 2011
If you’re trying to get from the couch to the fridge, you’ll probably be using vision to navigate and home-in on your fresh drink. To make your camera-equipped robot do something similar, ...

Finding outdoor odor sources using particle filters

  05 Apr 2011
Robots with smell could be used to find sources of toxic gas, search for drugs, locate survivors under rubble or hidden mines. Robots have an advantage over sniffer dogs since they can enter dangerous...

Global Hawks in the crowded Mediterranean airspace

  24 Mar 2011
The use of UAVs has skyrocketed, a wide variety of systems ranging from extremely small flying bots to large airframes like the Predators or Global Hawk drones is currently in use, mostly from armed ...

Robots get students motivated to pursue STEM careers

  17 Mar 2011
Robotics is a great way to engage young students in science, technology, engineering, and mathematics (STEM) subjects. With this in mind, researchers from the University of Massachusetts Lowell (UML)...

Integrating path planning and robot control

  07 Mar 2011
There is often a conflict between planning the path a robot should take to achieve a desired task (high-level control) and the motion control needed for the robot to follow this path (low-level contro...

Real-time behavior-based control

  22 Feb 2011
Using behavior-based controllers, robots are theoretically able to rapidly react to their environment. This is typically done by having several behaviors, that map sensory input to actuator commands, ...

Simulated pronking robots move like springboks

  14 Feb 2011
If you’ve never seen a video of springboks gracefully pronking, have a look below. Pronking is a gait where all legs are used in synchrony, usually resulting in relatively slow speeds but lo...

High-speed walkers pretend to go downhill

  03 Feb 2011
The typical way to make a bipedal robot walk is to actuate its leg joints, strap a bunch of sensors to measure its state and add a tight control loop to make sure it is performing the desired steps. I...

Learning Bayesian filters without precise ground truth
