HUM[erus] has been initiated with the construction of a first prototype (Prototype 1.0), made out of plexiglass components that rotate with the electromechanical computer-aided support of four servo motors. When folded, the size of the robotic arm does not exceed a 8 x 8 x 30 cm volume, while the range of workspace available that it offers corresponds to approximately 45 x 45 x 20 cm. Prototype 1.0 is characterized by a rather minimal and functionality–oriented approach to robotic design, with the connections of the parts being clearly visible and mechanically understood. Furthermore, the use of servos has been carefully selected as the best option among several motor types, first and foremost because of their low price and small size in relation to their high torque capacity, and secondly because of their simplicity in terms of software control and circuit linkage.
