With Prodrobot, the patient’s weight must not exceed 50 kg. Growth is limited primarily by the length of the limbs. This is due to the distance between the axis of the joints (ankle-knee, knee-hip), which should be between 29 and 37 cm for each pair of joints. This translates into a total patient height in the range of about 110 to 150 cm height. An important parameter is also the width of the hips, which can not howl more than 29 cm.
In contrast, Prodrobot Magna is adapted for patients between 140 and 200 cm height and weighing up to 130 kg.
