Past Present Future

Robots have been around for quite a while now. From their first appearances, to where they stand now, they have come a long way through technical developments. And, we are already getting used to the idea of them helping us. But to what extent? At what point can we see a robot in every household, not only helping us with day to day tasks, but also with more sophisticated issues. In many different companies, they are already dependent on robots. This is due to their newly found mobility. Just think of Amazon’s latest delivery, hovering robot and you will know what we are talking about.



From Nanobots to da Vinci surgical robots, each offers different and important business values that can be seen in logistics, the medical sector, space and the U.S. army. We have seen how robots are able to improve the driving abilities of the Bugatti Veyron or to drive a car completely on its own, thanks so artificial intelligence. The da Vinci surgical robot represents a new era in medical technology, as it helps to eliminate human error. The robots that have been developed by NASA have done a lot of research for us, which we could never have done on our own. And just as well, the U.S. army is helped by robots in places where no human being can go.



Humanoids are the group of robots that represent the most tangible and most typical human-machine interaction. Think back to R2D2 and then take a look at Asimo. The features of robots today are much more humanlike, as their faces resemble a human's. Their intelligence is so advanced that we are really starting to feel and treat them as human beings. The way they are able to recognize objects and persons, to react in different situations without any intervention, creates the opportunity to employ them in a wide range of activities: from serving a dinner in a restaurant to doing dangerous rescues in a nuclear plant. Together, we are approaching a new age of robot-human collaboration.



But of course we still have a long way to go. As many of the advanced robots are still in the beginning stages of development, small productions often come with big costs. Every new invention, every new step towards artificial intelligence presents new problems. Robots are dependent on the way we create and program them; that means that they are a product of the human mind, and therefore bound to human errors. Their mobility has already come a long way: Asimo can run up and down stairs and the Packbot can pick itself up. But still, they are a long way away from the movements and the mobility of a human being. Another constraint, that we as human beings also lack, is power. We need food and sleep, just as robots need to recharge their batteries.  Hopefully over time, these limitations will be eliminated one by one. But, we are going to have to wait a little longer before we can send a robot to get our groceries, or let a robot bring goods from a distributor to a retail centre.

And they shall rise to protect the Human Race...

Robots are able to traverse where humans dare not, into disaster areas, both natural and man-made. Governments, universities, and corporations across the globe have been investing significant resources in developing robots to deal with the repercussions of floods, mining collapses, oil spills, nuclear outbrakes, and other industrial and natural disasters since the 90's.

Robots, in essence, have no need of environmental comfort. Their chassis unite forged metallic alloys with synthesized polcarbonates that empower them to resist tremendous physical exposure to heat or steam (no air circulation), direct force or high frequency radiation, while being flexible enough to move around conveniently.

The limit of TID (total ionizing dose - deterioration of electric/electronic equipments because of temporally accumulated amount of radioactive exposure - absorbed dose [Gy]) for human workers is legally defined as 100 - 250 Milli-Sievert [mSv]. If the safety factor is set to 0.1 Gy, 50 [Gy] and 20 [Gy] (the admissible limit of a robot) are 20-50 times and 8-20 times larger the admissible limit of human workers respectively.

Robotic devices have been employed in response to multiple Radioactive disasters: Three Mile Island, Chernobyl and recently in Fukushima, Japan. In Fukushima, Packbots were used to measure radiation levels and take pictures safely (see video below). As for chemical and oil refinement disasters, robots have been vital in managing environmental damages. Clean-up robots, with huge, deployable arms, are able to analyze and collect chemical leakages within disaster areas.

In the medical field, robots have been developed to identify, analyze, and combat terminal diseases, such as cancer. Nano-robots, robots scaled to 10-9 meters, are being developed to access and cure malignant cells through magnetic field targeting. A big advantage of this robotic technology is that it targets only the infected cells, without damaging healthy tissue (like chemotherapy).


Robots are morevover used to explore active volcanos, which is just another example of how robots have extended humanity's learning horizons.

Below (left), a Hurt Locker-like bomb-disabling robot is pictured. Another example of how robotics has extended humanity's practical reach without endangering human lives. All of these robots have broken down environmental barriers, allowing humans to access realms previously inaccessible. Now just imagine what barriers robots will be able to overcome in the future.















This tactical hazardous operations robot, also know as THOR, is considered to be the robotic disaster response challenge (DRC) robot, par excellence. It not only facilitates the accomplishment of certain milestones in the prevention of disasters, but also pushes the entire field of robotic technology to its utter limits. At the end of the challenge, THOR should be able to perform the following tasks:
  • Get into and drive a utility vehicle
  • Walk across a rubble field
  • Clear rubble blocking an entry
  • Open doors and enter a building
  • Climb a ship’s ladder
  • Manipulate a power tool to break through a wall
  • Locate and close a valve
  • Carry and connect a fire hose
The business value of this technology manifests in the increasingly growing market and research & development found in this area. It seem that this technology not only provides a pruduct with respect to social responsibility or business ethics, but also from a pure return on investment point of view it seems to be beneficial.
