Icon identification minimum maximal distance b. camera-icon distance and c. Angle of vision 0 Distance cm K i Icon height pixels 20 149 30 100 40 75 50 60 60 50 Average K Table 1. Values obtained with laboratory measurements. 4. Experimental results Experimental tests were made to obtain the performance of the system in real conditions to this purpose an enclosed squared environment was built the iconographic symbols set as described before were and painted on the four different walls of the environment which represents four working icons areas. Experimental method Experimental tests showed very good results with real time performance of the system. Once the system was implemented and the practical operation checked the precision of the system was verified. In order to achieve this task we used different working regions for each working icon. For experiment purposes the area of the enclosed environment for each icon was divided in three zones with 20 40 and 55cms distances from each icon as shown in figure 13 Fig. 13. Divided zones for each working icon. 212 Robot Arms The difference between desired and real locations was measured and the results are showed in Table 2. Eight points were selected in a random manner for each zone and real desired physical coordinates were obtained. The camera was positioned on each selected point and the system calculated the positions to compare its results table 1 . The experiment was made for all points in all different regions for all different icons a graphical representation was made with the obtained values to get a better feedback of the system performance Figures 14 and 15 shows a graphics for two different icon working regions. Testing of the complete system with software and hardware integrated was done by selecting ten random points inside of the workspace then the camera along with a driver .
