Algorithm Controls

arm_illustrationSo – you’ve built a robot arm. Now you’ve got to figure out how to control the thing. This was the situation I found myself in a few months ago, during my Masters project, and it’s a problem common to any robotic application: you want to put the end (specifically, the “end effector”) of your robot arm in a certain place, and to do that you have to figure out a valid pose for the arm which achieves that. This problem is called inverse kinematics (IK), and it’s one of the key problems in robotics.

This year marks the occasion of ROS turning 9 years old! Over the years, ROS has grown into a strong world-wide community. It’s a community with a large variety of interests: from academic researchers to robotic product developers, as well as the many robot users. Academic use of ROS continues to grow. Citations of the first ROS paper “ROS: An Open-Source Robot Operating System” has grown to 2,871.

In this episode, Christina Brester interviews Vladimir Stanovov, PhD student and researcher at the Siberian State Aerospace University (Krasnoyarsk, Russia). Stanovov speaks about a speech-controlled wheelchair, which seeks to provide people that are quadriplegic, that is people with partial or total loss of use of their limbs and torso, with the possibility to control their wheelchairs through voice commands. In this interview Stanovov discusses the basic parts of the speech-controlled wheelchair, the fuzzy controller he created, and the trials they had in the medical center.

Research and development of robotic assistive technologies has gained tremendous momentum in the last decade due to several factors such as the maturity level reached by several technologies, the advances in robotics and AI and the fact that more than 700 million of persons have some kind of disability or handicap. For many people with mobility impairments, essential and simple tasks, such as dressing or feeding, require the assistance of dedicated people. Thus, the use of devices providing independent mobility can have a large impact on their quality of life.

In this episode, Audrow Nash interviews Hugh Herr, Director of the Biomechatronics Group at MIT. Herr talks about the accident that led to the amputation of both of his legs below the knee and how this shaped his rock climbing and academic career. Herr also discusses orthoses and exoskeletons developed by his research group, as well as the future of bionic technology.

In this episode, Audrow Nash interviews Emo Todorov, Director of Movement Control Laboratory at the University of Washington, about a physics-based optimization method for controlling robots. Todorov describes how his physics-based method can be used to solve problems and discusses results in simulation and on hardware.

In this episode, Audrow Nash interviews Karl Iagnemma, a Principal Research Scientist at the Massachusetts Institute of Technology and the CEO of nuTonomy, about autonomous vehicles in urban environments. Iagnemma discusses the market for autonomous cars, why nuTonomy is being developed and, at least initially, deployed in Singapore, and the technology of autonomous cars.

Last week Raffaello D’Andrea, professor at the Swiss Federal Institute of Technology (ETH Zurich) and founder of Verity Studios, demonstrated a whole series of novel flying machines live on stage at TED2016: From a novel Tail-Sitter (a small, fixed-wing aircraft that can optimally recover a stable flight position after a disturbance and smoothly transition from hover into forward flight and back), to the “Monospinner” (the world’s mechanically simplest flying machine, with only a single moving part), to the “Omnicopter” (the world’s first flying machine that can move into any direction independent of its orientation and its rotation), to a novel fully redundant quadrocopter (the world’s first, consisting of two separate two-propeller flying machines), to a synthetic swarm (33 flying machines swarming above the audience).

The idea of connecting brain-inspired models of computation to robots is probably as old as the discipline of robotics itself. Today, researchers are connecting robotics with neuroscience in order to both build intelligent robots and to better understand the brain. The workshop Advances in Biologically Inspired Brain-Like Cognition and Control for Learning Robots at IROS (Hamburg) brought together experts from diverse fields in brain-based robotics, neurorobotics, artificial neural networks and machine learning to discuss the state of the art.

Getting drones to fly around without hitting things is no small task. Obstacle-detection and motion-planning are two of computer science’s trickiest challenges because of the complexity involved in creating real-time flight plans that avoid obstacles and handle surprises like wind and weather. In a pair of projects announced this week, CSAIL researchers demonstrated software that allow drones to stop on a dime to make hairpin movements over, under, and around some 26 distinct obstacles in a simulated “forest.”

The Flying Platform is a new flying machine developed at the Institute for Dynamic Systems and Control at ETH Zurich. Its purpose is to study the use of electric ducted fans as control and propulsion systems for flying machines in applications where size is limited and high static thrusts are required, for example in aerial vehicles capable of vertical take-off and landing (VTOL), hovercrafts or even actuated wingsuit flight. The video below shows how the thrust vectoring is used to stabilize the vehicle.
