After two years of steady growth, industrial robots sales in the UK fell by 15 percent in 2018 compared to 2017, according to new figures from the British Automation and Robot Association (BARA). BARA chairman Mike Wilson told Drives & Controls that a lack of end-user knowledge in the UK means that users are unable to identify opportunities and produce usable specifications for robotic automation. BARA recently launched the UK's first robot integrator certification scheme in association with the Robot Industries Association.

Cries of "Noooooo!" were heard among space bot fans Wednesday as news emerged that NASA's recording-breaking, Mars-exploring rover Opportunity is (as feared) officially dead.
Designed to withstand a mere 90-day mission, Opportunity touched down on the Martian surface way back in Jan 2004. From that moment through to the summer of 2018 (when a planet-wide dust storm rendered the solar panels unusable) the bot has traveled 28.06 miles (45.16 km). That's further than any other vehicle on the surface of another world and along the way it sent back reams of data and helped terrestrial scientists make important discoveries.

14.5 years of operation is a spectacular achievement, especially given the extreme conditions Opportunity operated in. Consider this: Most of us get an average of three years use out of our laptops. If 'the laptop' were a unit of time measurement, Opportunity was operational for 4.83 laptops, its IT systems surviving all the while on a sole diet of software updates. That's impressive by any standard --even makeyup ones!
Colorado State assistant professor Jianguo Zhao has created new kind of robot that can melt down and then reharden its plastic joints to change their configuration. With new joint configurations come new motions, so this little reconfigurable bot (and bots like it) could end up with a large repertoire of moves at its disposal. (H/T IEEE Spectrum)

- How Much Dexterity Does a Robot Need?
What does it mean when a robot is described as "dexterous." And what does it mean for robot users? Here's what to look for when you're selecting a robot based on its dexterity.Start Production Faster with Robotiq Grippers.
The word "dexterity" is thrown around a lot in the robotics world. It's used by robot manufacturers who describe their robots as dexterous. It's used by robotics researchers who describe the dexterity of their developments. It's used by gripper manufacturers who describe their grippers as dexterous.
You might ask: How much dexterity does my robot need to have?
The answer: It's impossible to say. Nobody can seem to decide what makes a robot dexterous.
Robotic dexterity is a complex topic. It's hard to tell how much dexterity you'll need for a particular robotic application — or even if "how much" is the right question to be asking.
Robotic dexterity = a moving goalpost
To understand why this is a tricky topic, it's useful to look at an example.
Last year, a research team from UC Berkeley claimed that they had created the "most dexterous robot ever created".
When I heard the news, I was skeptical. Not because I doubted that they had made a technological breakthrough. I was skeptical of the word "dexterous". I knew from experience that this word is a moving goalpost in the world of robotics.
You see, I investigated robot dexterity as part of my PhD, which I completed back in 2014. During my research, I discovered that there is no standard definition for "dexterity" in the robotics community. As a result, researchers often claim that their robot is "dexterous" without defining what this means.
This makes it very difficult for robot users.
If we don't know how dexterous a robot is, how can we tell if it's the right one for our task?
I was right to be skeptical. The UC Berkley team had done what many researchers have done in the past. They had invented an entirely new metric to measure dexterity. Their metric ignored the physical properties of the robot and instead focused on machine learning performance. There's nothing inherently wrong with their new metric — which is really a measure of bin picking speed — but it certainly can't be used to prove that the researcher's robot is "the most dexterous robot ever created." In order to say that, you'd need to measure all dexterous robots using the same metric.
This is not an isolated case. I've seen the same thing happen again and again. People use their own definition to try to prove a robotic system is dexterous.
There is no standard metric for dexterity — not until ISO nails it down at least. Unfortunately, that means you have to find your own way to assess a robot's suitability for your task.
How to discover the dexterity needs of your task
The solution is to ignore the claims of "dexterity" made by manufacturers, the media, or researchers.
Instead, you should look closely at your robotic task and assess the specific performance that is vital for each of the steps. You can use this information to come up with your own definition of dexterity for your specific application.
Here are some of the important factors which relate to robot dexterity, along with questions that you can ask yourself to narrow down the needs for your task:
- Object size — How small are the objects that the robot will manipulate? Are there a variety of sizes or are all objects identical? How does this compare with the reach required of the robot?
- Object shape — What shape are the objects? Do they have many complex edges or a simple geometrical shape? Are they spherical or otherwise difficult to grasp?
- Gripping strategy — What are the different ways that the objects can be grasped (e.g. with an encompassing grip, internal grip, or suction)? Are there different ways to grasp the same objects? Are the objects delicate and so require a particular gripping strategy?
- Reachability — How much does the robot have to "stretch" to reach all important locations in the workspace? Does it need to use all the robot's workspace, or just a small part of it? Does it need to approach locations from many different angles?
- Speed — What cycle time is required for each action?
We sometimes think that factors 1-3 are only related to the robot's gripper and factors 4-5 relate to the manipulator. However, they are all inter-related. One factor in isolation does not necessarily define the robot as "dexterous" (e.g. a fast robot is not always dexterous), but together they give a picture of the dexterity needs of the task.
- Read more: End Effector Gripping Strategies
I should add that there are probably other factors besides those which I've listed which contribute to a robot's dexterity, but these 5 are a good place to start.
Examples: High-dexterity tasks vs low-dexterity tasks
Let's look how these factors relate to some fictional examples.
Example 1: A high-dexterity assembly task
The task involves picking up several small, tough parts (1-3mm wide) with a variety of complex geometrical shapes. The robot needs to rotate the parts to align them and then assemble them together. Then, the robot must move 1.5m to the other side of its workspace to insert the assembled parts into a box. A cycle time of 30 seconds per part is required.
Relationship to this task's dexterity
The objects are very small, particularly considering the large reach required to the robot (1.5m).
Objects are a variety of shapes which means that the gripper will need to be adaptable.
The shapes are geometric, so flexible grasping is likely to be needed. The objects are tough so don't need delicate handling.
The manipulation will be focused on two far-apart areas of the workspace. In the assembly area, it may need to be approach the objects from various angles.
The required cycle time is very small for such a complex assembly application.
Most of the factors suggest a high degree of dexterity.
Example 2: A low-dexterity pick and place task
The task involves picking medium-sized, cuboid objects from one part of the workspace and placing them at an inexact location a short distance away. The objects are quite fragile and a cycle time of 30 seconds is required.
Relationship to this task's dexterity
The objects are not small and do not need to be placed precisely.
The objects are a uniform, basic shape which is easy to grasp.
The objects are a basic shape, but they are fragile so a force-limited or vacuum gripper may be necessary.
Very little of the robot's workspace is required.
The cycle time is low for the simple task and short distance required.
Most of the factors suggest a low degree of dexterity, despite the fact that the objects are fragile.
How to pick the best robot and gripper for you
As you can see, the dexterity required for a task can't be defined by a single factor. Various properties of both the robot and its gripper will combine to determine the system's dexterity.

Meet our EuRobotiq Team - The interview
How did you start working with Robotiq?
After completing my Master’s degree in International Management in France, I spent some time in Buenos Aires working for the Argentine-Canadian Chamber of Commerce. I was just returning to Canada when I chanced across an opening at Robotiq. I knew I wanted a job that would allow me to stay close to my family yet also travel whenever wanderlust strikes. In addition, I’ve always enjoyed working in fast-paced environments, and knew I would love living in Quebec City.
I immediately knew Robotiq was the place for me! I identify strongly with Robotiq’s values of respect, positivity, creativity, practicality, teamwork, and family spirit. Robotiq team members inspire one another to embody our aspirations, both on and off the job.
What do you work on? What does that mean for the world?
I work closely with our partners and customers daily to make their projects as clear and simple as possible. It’s important to do this with a human touch to give the the client the best experience we can; “yes” is the word I want to hear, and “happy” is the feeling I want you to have when we work together.
I feel honored to help our partners and customers chase their goals; it’s so empowering to work with a wide range of partners who I genuinely love chatting to and meeting with every day. We are the infinite team (name of Team 8 at the RUC2018 Technical Challenge)!

As an added bonus, I have amazing colleagues—always ready for a beer, poutine, or a coffee. They even changed my tire for me one day when my bike had a flat!
What are your biggest values?
I am curious by nature, so continuous learning is very important for me. I am fascinated by how technology affects our daily lives, and I want to contribute to other people’s success. I also believe strongly in our mission at Robotiq: to free human hands from tedious tasks.
Because human contact is a priority for me, I love learning new languages: it lets me get to know people I might not have otherwise. My mantra in life is you get what you give, which keeps me motivated and working hard.
On a personal note, family is the most important thing to me. I especially love spending time with my brothers and nephew! They bring me joy, and I want to do the same for them.
What do you do when you’re not working?
I’m a traveler, an adventure seeker, always looking for new experiences.
I love challenging myself to step beyond my comfort zone. Life is to be lived to the fullest! I embrace life by spending much of my time with my family, doing sports, or discovering something new.
I’m constantly checking Google Flights and planning my next adventure. I always try to achieve something when I travel, like the physical challenge of the five-day trek to Machu Picchu in Peru, or skiing the Aiguille du Midi mountain in France. Next destination: Everest Base Camp in Nepal, perhaps?
P.S.: Although family is my top priority, sometimes I think it’s actually food! As M.F.K. Fisher said, “First we eat, then we do everything else.” What can I say? I’m a foodie.
