FRIDA Working With a Human

FRIDA(Friendly Robot for Industrial Dual-arm Assembly) is ABB’s dual arm robot. The robot was developed to work side by side with humans in the manufacturing environment. The aim of FRIDA is much similar to that of Baxtor from Rethink Robotics. It’s lightweight, human-safe with 2 arms, padded, adaptable to different situations, and low cost.

This video is a demostration of FRIDA at Automatica 2012 in Munich. Very interesting to see that the robot is aware of human present and give the lady a nudge when the lady forgot a part in assembly.   This gives the human the impression that the robot is “alive”. It did not have to talk or do anything complex. Just a simple nudge.

Dancing Robot Travis

Is this a robot or a moving speaker? Travis  is an better version of the Shimi. It is able to select songs from a library based on the rhythmic input.

This is not the only dancing robot around but another way to introduce robot technology to the real work through different mediums. Speakers docks are very popular given that most people own at least 1 smart phones. This reminds me a lot of the Sony Rolly.

Learning by Demonstration

It’s never easy to program a robot to perform a useful task. A person has to first attend a course or pick up some skills from a robotics manufacturer. There’s always a designated person in the factory that is able to program the robot and no one else. This is not true for a human operator as all we have to do is instruct the person to perform the task, and this is possible if you know the task to be accomplished.

Many researchers have worked on Learning by Demonstration and the following video is the work done at Willow Garage where they run trials on normal end-users. The end-users are able to physical move the PR2 to show it how to perform a particular task engaging the robot using speech recognition. This is one of the key things that will bring robots closer to a human centric environment.

Robots from ICRA 2012

This is the latest and greatest robots in the year 2012 was showcased at the ICRA (International Conference on Robotics and Automation, IEEE). Many robotics companies were there including, Adept Technology, Intuitive Surgical. Kinova Robotics and Willow Garage.

One of the more interesting robots present was the DARPA ARM program. It was developed using 2 WAM Arms from Barrett Technologies.

Foxconn’s First Robot is Here

Foxconn has been in the news lately plagued with the problems with human operators – under-aged workers, working condition and suicides. These will be a problem for any company and this situation will get worst as the cost of living in China is increasing. They decided to solve this problem by introducing robots into their lines. But rather than purchasing the robots from current manufacturers of robot, they have decided to start building robots themselves.





The robot in the picture is called the Foxbot and about 10,000 have been manufactured and deployed since 2011. These robots are pretty low cost priced at around $20k. According to International Federation of Robotics, there was a total sales of 160,000 robots in 2011. Their goal is to deploy 1 million robots by 2014 is 5 times that deployment. That’s an amazing feat by far and certainly good news for all robotists today. There’s going to be a growing demand for robots and all robotics related technologies in the near future.

Keepon is Not Alone

Keepon has been around for a while and used in the research field for helping children with autism with social interaction. It’s a very engaging robot, having such lively dance moves in-sync with upbeat music using the MAX visual programming platform.

Here are a couple robots that have similar functionality.

1) Spazzi

A MAKE magazine project by beatbots (maker of the Keepon) that puts together low cost components to create a keepon-like robot.

2) Romibo

A low cost (initial cost of $700) therapeutic robot with open source software for use by various researchers.

Charlie is Helping Autistic Children

There is a growing number of autistic children today. There are many established invention programs but there is limited progress in these methods. Different groups of researchers have been using robots as a tool to combat autism. Different robots have been used – mobile robots to teleoperated childlike robots to cartoon characters.

CHARLIE (Child Centered Adaptive Robot for Learning Environments) is the latest addition to this team of robots. Charlie was designed by Laura Boccanfuso of University of South Carolina. Charlie was create to improve communications skills of autistic children, in particular imitation and turn taking. Charlie has a camera that can do face tracking, IR sensors that measures the temperature of the subject and detachable arms to prevent damage in event the child gets a little rough.

Some robots in this area.

Singapore Empathetic Bear in a Nursing Home

This is not the first robot that is being introduced to elderly but it’s making an impact in Singapore. Paro, a japanese seal robot, has been named the “World’s Most Therapeutic Robot”. The bear is able to recognise emotion from the interaction. The bear has become a companion to the many elderly living in Singapore’s Villa Francis Home for the Aged. It’s good to see the smiles on the faces of the people interacting with the bear.

Robots Participating in DARPA Robotics Challenge

Meet the robots that are participating in this challenge. It’s really pushing the participants to outdo each other. Can’t wait to see some of these robots.

Velo 2G – Willow Garage has a New Gripper

Grippers that conform to objects surfaces are really useful. Some have looked at hand designs as all manmade should be made for grasp of the human hand. but it’s not easy to teach human grasp to a robot as we do grasp objects differently, e.g. how one holds a pair of chopsticks. I have seen different people holding a pair of chopsticks differently but yet able to finish a meal with the grasp. Secondly, it’s easy for humans to know how we are holding an object but it’s difficult to determine the orientation of the object if we use a robotic hand to hold the object.

The 2/3 finger design is simple and it can work really well maybe 90% of the time, which is good enough. Velco 2G is a passively adaptive gripper. It’s gripper is able to conform to any object it grasp. This is similar to the Robotiq grippers as well. BarrettHand is another gripper that’s falls in this category but it’s better because 2 of the 3 fingers of the BarrettHand can rotate  2 of the fingers around the palm axis and that allows changing the grasping style of the gripper. I find this useful for some applications.

Having the Velo 2G on the PR2 is great. It’s improves the grasp of the PR2 and i hope to see some innovation outside of software that can reduce the computation power requirements of the robot. My belief is that we need to produce robo-humancentric objects to improve the way the robots is able to perform task in a human-centric environment.
