“…Therefore, only the contact force is left for evaluation. 10 High quasistatic forces 11 can be achieved for this impact type as shown in Table 4. For the experiments L13 and L19 the robot is able to pass the singularity without exceeding its maximum nominal joint torques.…”

“…This shows that (with a granularity of 5 mm) the worst-case for this robot lies 10 In [16] we give an overview of facial fracture tolerance values. 11 Because the robot approaches a singularity the Cartesian velocity, which defines the impact velocity is quite low and therefore, the contact has no typical impact characteristics anymore. 12 Please note that L13 was not using a tension belt which reduces the effective value of d S because the seat can give in.…”

“…To our understanding, these investigations could be fundamental to robotic safety. Of course, classical impact experiments with knifes in forensic medicine, as described, e.g., in [11,35], did not take any robot behavior into account. It is clear that stabbing is likely to lead to a lethal situation and the fatality of this type of injuries needs very careful evaluation.…”

“…Stab wounds were investigated with different knifes and it was concluded that strain is not an appropriate measure to define a tolerance value for knifes and similar tools because the contact area is too small [11,35]. Instead, the evaluation of the penetration force is proposed, which seems to be a good and usable indicator for robotics.…”

The DLR Lightweight Robot III (LWR-III) developed at the German Aerospace Center (DLR) is characterized by low inertial properties, torque sensing in each joint, and a load to weight ratio similar to humans. These properties qualify it for applications requiring high mobility and direct interaction with human users or uncertain environments. An essential requirement for such a robot is that it must under no circumstances pose a threat to the human operator. To actually quantify the potential injury risk emanating from the manipulator, impact test were carried out using standard automobile crash-test facilities at the ADAC (German automobile club). Furthermore, we introduce our analysis for soft-tissue injury based on swine experiments with the LWR-III. This paper gives an overview about the variety of investigations necessary to provide a safety analysis of a human-friendly robot based on biomechanical injury results. We believe this paper can provide a guideline for the robotics community for future qualifications of other robots and thus serve as a key component to bring robots in our everyday life.

“…Although the forensic literature contains numerous publications describing the physics of stabbing (stab intensity, stab www.elsevier.com/locate/forsciint Available online at www.sciencedirect.com dynamics) [26][27][28][29][30][31][32][33][34][35][36][37], the studies are mostly concentrating on knife stabs, whereas there are hardly any investigations dealing with stab wounds caused by broken glass. The only paper was published by O'Callaghan et al [38] and describes the relation between velocity, energy and penetration depth of a thrown glass shard.…”

Injuries caused by sharp or pointed objects are common. They rarely cause fatal injuries, however, and the fatality rate is estimated to be 3% at most. Most fatalities caused by sharp force are homicides. The ratio of homicide to suicide is estimated at 6:1 to 5:2. When investigating deaths owing to sharp force, the forensic pathologist is expected to give an opinion on the following points: the type of injuries; the number and anatomical distribution of injuries; the shape, size, length, and depth of injuries; the object (weapon) used; the amount of force needed to inflict the injuries; the extent of internal injuries; the cause of death; and the victim's capability to act. These points are of decisive importance for the reconstruction of the sequence of events and, thus, are essential for distinguishing between self-infliction and involvement of another party. Most homicides by sharp force are committed by males, often under the influence of alcohol. The most common tool used is a knife, but other pointed 65
