NHK Documentary on Robotics

SCHAFT robotics is taking part in the DARPA Robotics Challenge. They are featured in this documentary by NHK

Flying Robot Have Legs

This is what you have seen with bats. They have legs within their wings. This is an interesting structure and consideration for a robot that we hardly think about. UAVs are usually developed for flight and with this approach the robot will be able to move around it’s environment in more ways than one.

This reminds me of RHex from Boston Dynamics. RHex is able to overcome almost all forms of terrain. Imagine with the ability to fly, RHex will be able to overcome more terrains and handle more situations. This certainly has use but it’s up to our imagination.

Zebro – RHex’s Brother

Zebro is a six legged robot conceptualised in TUDelft. It’s a brother of the RHex robot by Boston Dynamics. The aim of the research group is to study and develop control methods for platforms like the RHex. Various learning techniques are being used in the robot and studies are being done to improve the design of the legs and various components on the robot.

The RHex was able to perform locomotion in various undulating terrain. It’s a very promising form of a robot but is it scalable? It would be useful to see this platform scale up to perform task.

Robots are Building the Tesla Model S

WIRED has a recent article about the factory production of the Tesla Model S. The factory is producing around 400 cars a week and the production line is really impressive with the number of robots being used at every stage of production. This is really impressive for a company that started producing cars around 10 years ago. I am really impressed with the amount of automation.


Robot Cleaning the Sydney Harbour Bridge

This is the first time in history that the Sydney Harbour Bridge is being cleaned, not by human but by a robot. Sabre Autonomous Solutions, a Sydney robotics start-up,  has received a major investment from Burwell Technologies to commercialize the world’s first grit-blasting robot. Grit-blasting is a tedious process and can be highly hazardous for humans. On top of that, the robot is able to perform it’s task in areas that are difficult for human. There are many steel structures around the world and this robot will be useful for different structures. The funding obtained by Sabre Autonomous Solutions will be used to better the technology and improve the usability of the system.

Sabre Autonomous Solutions has it’s beginnings at University of Technology, Sydney (UTS). The technology developed allows the robot the ability to sense the steel structure and maps a path for the grit-blasting tool. Professor Dikai Liu of the Centre for Autonomous systems at UTS is the lead of the team that developed this technology.

RAPIRO – the latest addition to Kickstarter Robots

Raripo is the creation of Shota Ishiwatari. This is yet another low cost robot like the 3D printed robot – MAKI. It’s a pretty cute robot (rather small) with 12 motors and LED for effects. It runs off a Raspberry Pi and has a camera and PSD distance sensor to add to the ability to the robot. This is one of the first Raspberry Pi projects for robotics. Pledge £199 and you get yourself a robot with all the parts you need by the end of the year. He has already reached his goal with his kickstarter robot.

One interesting aspect of this project is that he will provide the STL 3D files that you can use for printing another set of the robot. The 3D printable robots are coming and it’s a very good idea given the microprocessors and computers are readily available almost everywhere in the world. There is no need to look for a manufacturer to get your parts made (high risk) and this is made to order which reduces the logistical problems.

Unboxing of Baxter from Rethink Robotics at OSRF

Baxter is new kind of robot that is trying to redefine manufacturing robotics. It’s the first robot built for industry with  intelligence and safety of humans in mind. A person is able to work closely with the robot and be able to teach baxter what to do just as he/she would with a human. This is interesting as we have to face the fact that Baxter is still far from human capabilities.

OSRF (Open Source Robotics Foundation), formed to engage the world to push the use of open source robotics software in any form of robotics. It would be great to see how they can make Baxter smarter and more capable in manipulation ,and understanding of both humans and environment.

Check out the excitement in the video!!

Omnidirectional Track Base

This is a very really interesting platform. It has the capability of a tracked base with omnidirectional track base capabilities. We typically use tracked robots as they are able to overcome various obstacles and handle even stair climbing. But there isn’t any track base to date that has omni directional capability.

This omni-crawler is from Osaka University and was developed using the omni-ball concept. The omni-ball design is made up of 2 hemisphere which rotates independently and it also rotates around the ball’s axis which allows the base to move as an omni-directional platform. They have plans to use this concept to develop an interplanetary explorer. This is certainly useful for mobile manipulation in different terrain (indoor or outdoor). I will be tracking the progress of this development closely.

Team ViGIR at DARPA Robotics Challenge

Team ViGIR is a team consisting of members from Virginia Tech, Technische Universität Darmstadt and TORC.

darpa DRC scenario

They will be taking part in Track B in the DARPA Robotics Challenge where they will use the PETMAN instead of developing their own robot. The task are shown in the chart above. TORC Robotics will take the lead developing the algorithms required for the humanoid to perform during the competition.

TORC has developed autonomous navigation kits for vehicles and they develop components for autonomous vehicles. Teleoperation with autonomy of vehicles is one technology that they have that will improve the usability of PETMAN robot. TU Darmstadt‘s Simulation, Systems Optimization and Robotics group will join the team. They have developed autonomous robot team and researched in dynamic modelling and optimisation methods in simulation. Last but not the least important is the Human-Computer Interaction Group from Virginia Tech. The team consist of groups with different expertises that make them suited for Track B.

Sliding Autonomy is a buzz word that is used widely in this competition and some feel that this will make the difference between the various teams. This is important as robots are still unable to perform robustly in the given scenario. Human intervention is still required and this is allowed during this competition. This makes it interesting when some form of autonomy is given to the robot but there are of course situations human teleoperation might be more suited. It’s about striking a balance depending on the capability of the robots. In Track B, all teams will use the PETMAN which means that they can concentrate on developing algorithms and teleoperation capabilities for use with the PETMAN. This is certainly a scenario that makes more sense today, as we take the first step away from teleoperating “dumb” robots. Heaphy Robotics was an initiative by Willow Garage a while back (watch video below) that allowed people from around the world to gain control of the PR2 to perform task without their premises. As seen in the video, you could either take full manual control over the robot or allow the robot some form of autonomy. That’s a good example of sliding autonomy.


Team Steel at DARPA Robotics Challenge

DARPA Robotics Challenge is the next grand challenge that’s really getting most of the robotics community on their toes. The goal of this program is to develop ground robots that are able to operate in degraded human-engineered environments performing complex task such as opening a valve, climb a ladder or even drive a car. This is in response to the difficulties faced by robots deployed during the Fukushima Daiichi nuclear incident. That revealed a lot about the current capabilities of the robots in the market today. It’s not that the robots are incapable but it’s a matter about using the wrong tool for the job.

Team Steel, led by Christopher Atkeson, is one of the two CMU teams taking part in the DARPA Robotics Challenge. They have selected to take part in Track B (using a DARPA-provided robot, the PETMAN) while their counterparts (TARTAN RESCUE, lead by Tony Stentz)  have chosen to take part in track A where members of that team will develop a robot of their own.


They have worked on the Sarcos Humanoid Robot, a robot similar to the PETMAN. They will implement some learning methods and interesting techniques for their robot. This will definitely be beneficial to the other team given CMU has fielded 2 teams in this competition.


BarBots are Serving Drinks

Bartending is never easy, even the many different kinds of cocktails and concoctions you have to remember.  On top of that, the amount of each liquid used makes or breaks a drink. The webtender is a site with all the recipes for the different cocktails you can find that every bartender might need. Sounds difficult for a human but say, we give this job to a robot..

Barbot 2013 is an annual showcase of robots that are designed to make and serve drinks. It’s great to see the different ideas that have been used to make these drink and the reward is a good cocktail always!! why not. It’s far more interesting than working on a dish washing robot.

MORSE – Simulator for ROS

Simulation is important for robotics but a realistic simulation is what is useful for most roboticists. In ROS, gazebo and Rviz are used for  visual and physics simulation but there’s always room for a better simulation. This took 4 years but it’s finally here. MORSE (Modular OpenRobots Simulation Engine) is the latest simulation tool available for ROS among other robotics architecture and middleware. It’s the most realistic simulation I have seen and it allows you to take control of how real you want the simulation to be.

It’s based on open source projects like Blender for 3D rendering and Bullet for physics simulation. It’s build on an established workflow and that’s allows the simulation to sit on these two establish platform. It allows single and multi robot simulation and has 20 classes of sensors from cameras, depth sensors to IMUs. It currently supports 4 open source middleware – ROS, YARP, Pocolibs and MOOS.

One interest aspect of MORSE is that it can handle multiple robots in joint simulation scenario and work together in a distributed network of simulation nodes. This is a server-client model and it allows the use of multiple systems to run the simulation smoothly with distributed computing.

Full documentation is available on their site.

Neato’s New Signature Robot

Neato is always under my radar due to it’s low-cost hackable LIDAR that came with the XV-11. It came with a 360 degrees scanning LIDAR with 1 degree accuracy and 10Hz scanning speed. This is a entire website dedicated to getting the xv11 to run under ROS. They have recently launched the XV Signature series. It looks really nice with it’s all black casing but even better still is the fact that this new Neato has 50% more suction power with the same hardware and specification.

Honestly, i am not really concerned about the vacuuming but i am rooting for Neato to build better, faster and more efficient low-cost solutions to the navigation ability to this robot. Hopefully, this will be a general base one day where we can hack it to sweep, mop, fetch and cook at very affordable prices.



A*STAR SERC Grant Call – Industrial Robotics Programme

Agency for Science, Technology and Research (A*STAR) is the agency for R&D in Singapore. The Science and Engineering Council (SERC) has a recent grant call for productivity driven robotics application. This is an opportunity for development of robot application to improve manufacturing productivity in Singapore.

This is a huge thrust in increasing productivity in Singapore, some what of a hot topic lately in Singapore. Singapore has many industries that are heavily reliant on human resource. It has been a difficult task for companies and the government to switch to automation. This maybe be the first step and there is hope that more steps will take place soon.
