Augmented Reality For Time-Delayed Telsurgical Robotics

Teleoperation brings the advantage of remote control and manipulation to distant locations or harsh or constrained environments. The system allows operators to send commands from a remote console, traditionally called a master device, to a robot, traditionally called a slave device, and offers synchronization of movements. This allows the remote user to operate as if on-site, making teleoperational systems an ideal and often only solution to a wide range of applications such as underwater exploration, space robotics, mobile robots, and telesurgery. The main technical challenge in realizing remote telesurgery (and similarly, all remote teleoperation) is the latency from the communication distance between the master and slave. This delay causes overshoot and oscillations in the commanded positions, and are observable and statistically significant in as little as 50msec of round trip communication delay. Predictive displays are virtual reality renderings, generally designed for space operations, that show a prediction of the events to follow in a short amount of time. It can be used to overcome the negative effects of delay by giving the operator immediate feedback from a predicted environment. Furthermore, it does not suffer stability issues that arise with delayed haptic feedback. Early predictive displays included manipulation of the Engineering Test Satellite 7 from ground control where the round trip delay can be up to 7sec and Augmented Reality (AR) rendering where the prediction is overlaid on raw image data. These strategies can be applied to telesurgery, but require overcoming the unique challenges in calculating and tracking the 3D environment for a full environment prediction, which includes non-rigid material such as tissue. Furthermore, prior work in the surgical robotics community highlights the need for active tracking rather than only relying on kinematic calibrations to localize the slave due to the millimeter scale of a surgical operation and the often utilized cable driven actuation.

New Method For Underwater Wireless Communication

Underwater communication presents many challenges in order to transmit data with large bandwidth and over long distance and/or over a wide area.  Indeed, water absorption, scattering and turbidity prevent radio waves to be used similarly as in air. Acoustic transmission has therefore been the standard technology for decades, but suffers from a very small bandwidth (less than 1 Mbps), whereas a video stream or conventional large data stream requires a bandwidth higher than 10Mbps.  Free Space Optical systems have been developed and tested underwater lately taking advantage of the development of lasers and LEDS with wavelengths around 500nm. In this range, water absorption is minimal and optical communication range could theoretically reach 150m with a bandwidth in the tens of Mbps. Large distance communication and correct alignment between the transmitter and the receiver remain however challenging.   UC Berkeley researchers have developed a new method for long-distance and/or wide­area underwater wireless communication using Autonomous Underwater Vehicles (AUVs) equipped with a Free Space Optical system allowing high bandwidth communication. The high stability and agility of the AUV allows to maintain a correct alignment between the receiver and the transmitter of two different AUVs keeping the data communication operational. 

Linear/Angular Position Stabilization & Control Of An Underwater Robotic System

There are several emerging applications for Autonomous Underwater Vehicles (AUVs) where the agility and accurate control of location and/or orientation is critical. In the presence of random ocean currents and waves, conventional AUV systems need to use a combination of their thrusters to generate an appropriate force/torque and cancel the external disturbance to maintain the desired attitude or position. This is a relatively slow response since it requires accelerating and pushing water around the vehicle body. Thus, existing AUVs have disadvantages: (i) accurate and agile orientation and position control/stabilization is challenging; (ii) since thrusters are operational during reorientation maneuvers, a substantial amount of power is consumed to pump the bulk fluid, wasting the precious power storage of the vehicle and thus reducing its operational time; and (iii) drag forces and torques exerted on the thrusters significantly affect the efficiency of reorientation maneuvers.   UC Berkeley researchers have designed a new device for fast stabilization and control of an underwater robotic vehicle. In this architecture, the attitude maneuvers are performed using reaction torques that the body of the vehicle gains from a central inertial system.

SpeakQL: Towards Speech-driven Multi-Modal Querying

Automatic speech recognition (ASR) systems currently in use work well for routine tasks such as posing a question to SIRI (Apple) or Alexa (Amazon), but do not interface with more complex datasets. Complex datasets take into account when the user considers a speech-driven system to query structured data, but these require new approaches. Some of these approaches have used new querying modalities such as visual, touch-based and natural language interfaces (NLIs) whereby user commands are translated into the Structured Query Language (SQL). Unfortunately these new proposals are not suitable for complex datasets.
