a full over-ride kill switch capable of cutting power to the system should any form of unanticipated event occur. The size and weight constraints are in place in order to prevent the system from hindering the user during the rehabilitation sessions. Many exoskeletons use a backpack to house the battery and various electronics. We are attempting to move away from this idea in order to reduce the size of the system. We will be using a battery belt in which two 12 [] batteries will be situated on each side of the hips. The weight of the batteries will be evenly distributed around the pelvic area reducing the added weight in the user upper section, thus reducing the chances of loss of balance. Weight limits for the entire system including the batteries have been set at 30% of the total weight of a child. An eight year old child that lies within the 95th percentile, will weigh on average 35 , limiting the system to a weigh of 10 [4]. Size is also limited by the target population and as listed in the user analysis the system should be able to accommodate children between the heights of and the system has maximum and minimum 3’0” 4’6”. Therefore adjustable lengths in the femoral and tibia regions shown in Table 3 below. Table 3: Adjustability ranges for exoskeleton Femur Tibia Maximum [cm] 35 30 Minimum [cm] 24.8 21.6 Statement of Accomplishments During the fall 2015 semester, we completed all of the objectives within the software and motor design categories of the goal analysis diagram shown in the Target Objective and Goal Analysis section. In order to complete these tasks, we converted gait data from a clinical gait analysis from degrees to voltage values, and used the voltage values to program the motors to perform the correct walking sequence. We compared the motor output to the graphs of the
