2. Apple trees need fertilizer. The best way our client has to spread fertilizer now is to use manpower with a casting system. This system is very inefficient and time consuming.

3. The most efficient way to fertilize a tree with the least amount of fertilizer is to spread it along the drip line of the tree. We used an automated device to spread fertilizer along the drip line based upon the average circumference of an apple tree.

4. Motor Control 1. Find tree trunk 2. Center itself on trunk 3. Back up to drip line 4. Tree radius: 6ft 5. Circle tree 6. Do a complete circle then exit

7. while(MIDDLE_BUTTON_GetVal()) { //Testing Middle Pushbutton if(LEFT_BUTTON_GetVal()==0){//Left Button is Pushed Right_SetDutyUS(FORWARD); //Turning Left (towards Tree) Left_SetDutyUS(REVERSE); Left_SetDutyUS(FORWARD); //Moving Forward if(RIGHT_BUTTON_GetVal()==0){//Right Button is pushed Left_SetDutyUS(FORWARD); //Turning Right (towards Tree) Right_SetDutyUS(REVERSE);
