3. 17 April 2007Gargo Introduction The purpose of the robot is to measure the dimensions and weight of the box and with the destination address it will calculate the cost of the shipment and display the result to the customer. The robot will also write the destination address, dimension and weight information into an RFID tag and put the packet onto the appropriate place considering the destination address

7. 17 April 2007Gargo Sensors-1 Bump Switches: − Two bump switches are used to detect obstacles Laser Pointers: − Three sets of laser pointer arrays are used for each dimension to detect the dimension on that axis Force Sensing Resistors (FSR): − Four force sensing resistors for measuring the weight of the box Photoreflectors: − TCRT 5000 IR reflectors are used as Tracker Sensor, the output pins for right, middle and left reflectors are controlled by the Mavric-II.

9. 17 April 2007Gargo Behaviors Gargo has several behaviors; (1) waits for the push button input to get the destination address (Gainesville, Florida or out of state) and start information (2) measures the dimension of the box and decides if it is big, small or smaller. (3) measures the weight of the box and decides if is heavy, light or lighter. (4) writes dimension, weight and destination address information to the RFID tag (5) obstacle detection (6) line tracking (7) push the box to the corresponding place in the destination area.
