The ability to automate forced landings in an emergency such as engine failure is an essential ability to improve the safety of Unmanned Aerial Vehicles operating in General Aviation airspace. By using active vision to detect safe landing zones below the aircraft, the reliability and safety of such systems is vastly improved by gathering up-to-the-minute information about the ground environment. This paper presents the Site Detection System, a methodology utilising a downward facing camera to analyse the ground environment in both 2D and 3D, detect safe landing sites and characterise them according to size, shape, slope and nearby obstacles. A methodology is presented showing the fusion of landing site detection from 2D imagery with a coarse Digital Elevation Map and dense 3D reconstructions using INS-aided Structure-from-Motion to improve accuracy. Results are presented from an experimental flight showing the precision/recall of landing sites in comparison to a hand-classified ground truth, and improved performance with the integration of 3D analysis from visual Structure-from-Motion.

A "ribbon" is a surface traced out by sweeping a constant width line segment along a spatial curve. We consider the problem of planning multiple disjoint and collision-free ribbons of finite thickness along curvature and torsion constrained curves in 3D space. This problem is motivated by the need to route multiple smooth channels through a 3D printed structure for a healthcare application and is relevant to other applications such as defining cooling channels inside turbine blades, routing wires and cables, and planning trajectories for formations of aerial vehicles. We show that this problem is equivalent to planning motions for a rigid body, the cross-section of the ribbon, along a spatial curve such that the rigid body is oriented along the unit binormal to the curve defined according to the Frenet-Serret frame. We present a two stage approach. In the first stage, we use sampling-based rapidly exploring random trees (RRTs) to generate feasible curvature and torsion constrained ribbons. In the second stage, we locally optimize the curvature and torsion along each ribbon using sequential quadratic programming (SQP). We evaluate this approach for a clinically motivated application: planning multiple channels inside 3D printed implants to temporarily insert high-dose radioactive sources to reach and cover tumors for intracavitary brachytherapy treatment. Constraints on the curvature and torsion avoid discontinuities (kinks) in the ribbons which would prevent insertion. In our experiments, our approach achieves an improvement of 46 % in coverage of tumor volumes as compared to an earlier approach that generates each channel in isolation.

A stable autonomous underwater vehicle (AUV) is essential for underwater survey activities. Previous studies have associated poor results in bathymetry survey and side-scan imaging with the vehicle's unwanted roll motion. The problem is becoming more prominent as AUVs are smaller nowadays. This causes reduction in the metacentric height of the AUVs which affects the inherent self-stabilization in the roll-axis. In this paper, we demonstrate the use of an internal rolling mass (IRM) mechanism to actively stabilize the roll motion of an AUV. We rotate the whole electronics tray, which has an off-centric center of gravity, to produce the required torque to stabilize the roll motion. The mechanical design of such mechanism and its dynamics modeling are discussed in detail. A Proportional-Integral (PI) controller is synthesized using the identified linear model. Results from tank tests and open-field tests demonstrate the effectiveness of the mechanism in regulating the roll motion of the AUV.

This paper presents an approach to mobile robot localization, place recognition and loop closure using a monostatic ultra-wide band (UWB) radar system. The UWB radar is a time-of-flight based range measurement sensor that transmits short pulses and receives reflected waves from objects in the environment. The main idea of the poposed localization method is to treat the received waveform as a signature of place. The resulting echo waveform is very complex and highly depends on the position of the sensor with respect to surrounding objects. On the other hand, the sensor receives similar waveforms from the same positions. Moreover, the directional characteristics of dipole antenna is almost omnidirectional. Therefore, we can localize the sensor position to find similar waveform from waveform database. This paper proposes a place recognition method based on waveform matching, presents a number of experiments that illustrate the high positon estimation accuracy of our UWB radar-based localization system, and shows the resulting loop detection performance in a typical indoor office environment and a forest.

We study the topology of the space of coverings for a metric tree with disks embedded in the tree. Focusing on the coverings with excess one disk, we prove that its topological structure is that of a Cayley graph of the permutation group S-n. What follows is a centralized algorithm for stabilizing periodic swarm coverings based upon feedback control with the designed vector field on a maximal subset of the space, removing discontinuity loci.

We consider the problem of computing the maximum-reward motion in a reward field in an online setting. We assume that the robot has a limited perception range, and it discovers the reward field on the fly. We analyze the performance of a simple, practical lattice-based algorithm with respect to the perception range. Our main result is that, with very little perception range, the robot can collect as much reward as if it could see the whole reward field, under certain assumptions. Along the way, we establish novel connections between this class of problems and certain fundamental problems of nonequilibrium statistical mechanics. We demonstrate our results in simulation examples.

As technology has advanced, electronic components and systems have become smaller and more powerful. A similar trend holds for space systems, and satellites are no exception. As payloads become smaller, so too can the launch vehicles designed to carry them into orbital trajectories. An energy analysis shows that a rocket system with as low as tens of kg of fuel can be sufficient to deliver a 10g payload into orbit given a sufficiently low mass autonomous rocket flight control system. To develop this, the GINA board, a 2g sensor-laden wireless-enabled microprocessor system, was mounted on a custom actuated rocket system and programmed for inertial flight control. Ground and flight tests demonstrated accurate dead reckoning state estimation along with successful open loop actuator control. Further experiments showed the capabilities of the control system at closed loop feedback control. The results presented in this paper demonstrate the feasibility of a sufficiently low mass flight controller, paving the way for a small scale rocket system to deliver a 10g attosatellite into low Earth orbit (LEO).

This paper introduces a local motion planning method for robotic systems with manipulating limbs, moving bases (legged or wheeled), and stance stability constraints arising from the presence of gravity. We formulate the problem of selecting local motions as a linearly constrained quadratic program (QP), that can be solved efficiently. The solution to this QP is a tuple of locally optimal joint velocities. By using these velocities to step towards a goal, both a path and an inverse-kinematic solution to the goal are obtained. This formulation can be used directly for real-time control, or as a local motion planner to connect waypoints. This method is particularly useful for high-degree-of-freedom mobile robotic systems, as the QP solution scales well with the number of joints. We also show how a number of practically important geometric constraints (collision avoidance, mechanism self-collision avoidance, gaze direction, etc.) can be readily incorporated into either the constraint or objective parts of the formulation. Additionally, motion of the base, a particular joint, or a particular link can be encouraged/discouraged as desired. We summarize the important kinematic variables of the formulation, including the stance Jacobian, the reach Jacobian, and a center of mass Jacobian. The method is easily extended to provide sparse solutions, where the fewest number of joints are moved, by iteration using Tibshirani's method to accommodate an l(1) regularizer. The approach is validated and demonstrated on SURROGATE, a mobile robot with a TALON base, a 7 DOF serial-revolute torso, and two 7 DOF modular arms developed at JPL/Caltech.

Precise Velocity Estimation for Dog Using Its Gait 9

We aimed to record and visualize the investigation activities of search and rescue dogs. The dog's trajectory is required to create this visualization, and the dog's velocity needs to be determined to estimate its trajectory. In this study, we examined a method for velocity estimation that uses a dog's gait. We measured a Labrador dog's gaits (walk and trot) and analyzed the gait data. From the gait data, we found that there are cyclic moments when the dog's velocity vector faces its heading direction. This fact enables the reconstruction of the velocity vector v = (v(x), v(y), v(z))(T) from the dog's speed Ivy and pose. We devised a precise estimation method for a dog's velocity and evaluated its accuracy. From the evaluation results, we confirmed that the gait-based velocity estimation was more accurate than velocity estimation based on the extended Kalman filter when v was obtained at 1, 5, and 10 Hz. This result can pave the way for using a mobile phone to estimate a dog's trajectory.

In this paper we present an approach to tree recognition and localisation in orchard environments for tree-crop applications. The method builds on the natural structure of the orchard by first segmenting the data into individual trees using a Hidden Semi-Markov Model. Second, a descriptor for representing the characteristics of the trees is introduced, allowing a Hidden Markov Model based matching method to associate new observations with an existing map of the orchard. The localisation method is evaluated on a dataset collected in an almond orchard, showing good performance and robustness both to segmentation errors and measurement noise.
