8. Needs Analysis

9. Feasibility Analysis AttributeScaleWhySolution R1 Sufficient Skills5The Project is programming intensive and we have the required experience. None R2 Sufficient Equip4The team has the funds to acquire the necessary equipment, though on a small scale. Most lab equipment will be enough, and team can use laptops which are already obtained Need to create a budget for equipment that is as of yet unattained R3 Technology3For the most part the technology needed to complete this project is available. However, GPS devices have a 3m error which could be a problem. Research techniques which could solve this problem such as using ground reference points. R4 Sufficient People4There are 4 members which is enoughNone S1 Sufficient Time3Creating a reconnaissance vehicle is an extensive project which may require a large commitment in order to fully complete. Get started as soon as possible. E1 Sufficient Funds3The team has the funds needed to acquire the necessary equipment, though on a small scale. Replacement equipment do to random errors will be costly however Save money just in case of damaged equipment. Assume we may need 2 of every, and save money accordingly. Total22 Average3.7

10. Objective List 1.Should be able to independently maneuver to a desired location. 2.Should be able to receive commands and report information. 3.Should be able to gather information about its current location. 4.Should have an acceptable battery life. 5.Should be modifiable to better suit various mission types. 6.Should be capable of operation in night and day and in hot or cold.

11. Operating Environment The vehicle will be able to maneuver: Paved Road Grass and Inclines Rocky and sandy desert type environment In Hot and Cold Climates The Vehicle will not be able to maneuver: In Rain Wet Environments Snow Dense Foliage
