Disturbance Observer based Linear Feedback Controller for Compliant Motion of Humanoid Robot.

Abstract Actuator modules of humanoid robots have relatively higher joint elasticity than those of industrial robots. Such joint elasticity could lead to negative effects on both the tracking performance and stability for walking. Especially, unstable contact between the foot and the ground caused by joint elasticity is a critical problem to decrease the stability of position-controlled humanoid robots. In this…

Japanese Humanoid Robot Dominates DARPA Challenge

A Japanese robotics team dominated the field after an ambitious two-day competition that saw robots driving cars, climbing ladders and wielding power tools. A two-legged robot built by engineers at SCHAFT Inc., a Japanese robotics firm, won the DARPA Robotics Challenge Trials(Dec. 21), scoring the most points across tasks that tested the robots’ mobility, dexterity, perception and autonomous operations. Florida-based…

Robot cooks make pancakes

Cooking is an art sometimes forgotten in the robotics world, but James, the PR2 robot, and Rosie, another robot from CoTeSys (Cognition for Technical Systems) in Munich have joined forces to show that robots can be of great use in the kitchen as well. They made some pretty successful-looking pancakes and used various tools around the Assisted Kitchen to show off their skills.…

Hoaloha Robotics Developing Socially Assistive Hardware Platform

  Last we heard from Hoaloha Robotics was back in September of 2010, when the company was initially founded by Microsoft veteran Tandy Trower, who’d led the Microsoft Robotics Group for several years. According to some press at the time, Hoaloha was all about “developing a common interface and software that will make assistive robots easy to use and customize with applications, similar to…

Tiny Jumping Robot Finds Room for a Tail

I wanna introduce tiny jumping robot which can find room for a tail. I was impressed because of how tiny it was, but also because it could change direction, self-right, and jump, all using just one single motor and a clever arrangement of gears. A new upgrade (inspired by research from UC Berkely) adds a tail to the mix, giving this…

Pointclouds from outdoor stereo cameras

source: http://www.pointclouds.org We tested an algorithm, developed by Alex Trevor in the previous HRI code sprint. This algorithm segments points using their normal distribution, this makes it very sensitive to noise. Basically, this algorithm computes a disparity for a stereo pair using its own dense matching method, implemented by Federico Tombari. But I additionally tested it using disparity maps precomputed by HRI. Here…

A Teeny, Tiny Autopilot

Source : IEEE Spectrum I want to introduce tiny autopilot. It looks like a bug. Below posted By Philip E. Ross Researchers in the Netherlands have designed a thumbnail-size autopilot system that they say is the lightest in the world, at just 1.9 grams.  That should free up a fair amount of carrying capacity for the micro air vehicles (MAVs) that…

If, that is, you’re connected to one of 50 Japanese medical institutions now testing and evaluating a pair of the semi-robotic exoskeletal assistive devices. Honda breaks down the what’s-it-do-and-how as follows: “The [Walking Assist Device’s] control computer activates motors based on information obtained from hip…

Carsim Mechanical simulation

Today, I want to introduce carsim simulation program, and show how VehicleSim models can be extended using simulink(Matlab). Carsim Introduction Video CarSim simulates the dynamic behavior of passenger cars, racecars, light trucks, and utility vehicles. CarSim animates simulated tests and outputs over 800 calculated variables to plot and analyze, or export to other software such as MATLAB, Excel, and optimization…
