The mobility aid comes in the form of a backpack with two telescopic robotic arms ending in grabs. Their movement is controlled by a controller positioned so that the user is able to reach it comfortably. The new product introduces a number of advantages compared to aids currently available in the market. The backpack’s construction enables the user to easily put it on and take it off without having to seek assistance, or having to take off any clothes. The backpack also supports good body posture. The device is adaptable, does not hamper movement and is small in size, has a compact shape and low weight. The user is given intuitive control, which offers feedback and enables the gripping strength of the grab to be felt. 

Phocomelia (from the Greek φώκη = “seal” and μέλος = “limb”) is a congenital disorder in which the upper limbs abut directly against the shoulder girdle and the lower limbs against the pelvic girdle.

In the 1950s and 1960s occurred the so-called thalidomide epidemic. Pregnant women were prescribed medicines containing thalidomide for morning sickness and as a sedative. At that time an increased number of children were born with a congenital disorders and limb defects. Later, it was proven that these defects were caused by thalidomide. It is estimated that over 12 000 children were thus affected.
