Hand pose replication using a robotic arm

Robotics is the future. Simple but true. Even today, they support us, make the products we need and help humans to get around. Without robots we would be worse off.  Kirsty Aquilina (supervised by Dr Kenneth Scerri) developed a system where a robotic arm could be controlled just by using one’s hand.

The setup was fed images through a single camera. The camera was pointed towards a person’s hand that held a green square marker. The computer was programmed to detect the corners of the marker. These corners give enough information to figure out the hand’s posture in 3D. By using a Kalman Filter, hand movements are tracked and converted into the angles required by the robotic arm.

The robotic arm looks very different from a human one and has limited movement since it has only five degrees of freedom. Within these limitations, the robotic arm can replicate a person’s hand pose. The arm replicates a person’s movement immediately  so  that a person can easily make the robot move around quickly.Controlling robots from afar is essential when there is no prior knowledge of the environment. It allows humans to work safely in hazardous environments like bomb disposal, or when saving lives performing remote microsurgery. In the future, it could assist disabled people.

This research was performed as part of a Bachelor of Engineering (Honours) at the Faculty of Engineering.

PHONE STORY

Game Review_Costantino

 

What is the story behind our smart phones? Phone Story retraces the production stages of our favorite products, showing us the dramatic working conditions behind their assembly. It seems like Apple didn’t like it: the game is now banned from the App Store.

Mass riots and frequent suicides shed a dark light on Foxconn, the company that assembles product for the likes of Apple, Microsoft, and Amazon. Afterwards, it became impossible to ignore the conditions of the workers that mass-produce contemporary tech gadgets.

Enter Molleindustria, the software house funded by Paolo Pedercini, responsible for a remarkable series of ferociously satirical, “serious” games (check molleindustria.org for more — it’s worth it). Phone Story takes us through an uncomfortable ride of funny minigames with classic, familiar mechanics juxtaposed to harsh vignettes: underage miners extracting silicon, suicidal workers jumping from the roof of the factory, and an army of Apple — pardon, “Pear” — fans taking a flagship store by storm.

Don’t expect a radical new gaming experience with Phone Story, but pick it up if you’d like to reflect on the process that brought you your mobile, while you’re
actually holding it in the palm of your hand.

Moving objects with your mind

Decades-long research into the field of brain to computer interface (BCI) devices seems close to bearing fruit. These devices could provide communication tools to Malta’s growing number of older people and the disabled, while local gaming companies could exploit a new niche entertainment market. Words by Dr Edward Duca.

LOOKING UP TO THE SKIES

Malta is involved in the creation of the largest telescope ever built, the Square Kilometre Array. The telescope will be composed of 10 million antennas, process petaflops of data per day, and cost 1.5 billion euros. When built the array will peer deep into space to see how the first stars were born and attempt to solve the riddle of our origin. Words by Dr Kris Zarb Adami and Dr John Abela.
