1. User Interface (hardware)

2. Overview  Translate user actions into electrical control signal which controls the robot movement  Be able to input and store coordinates and translate that into control signals that can autonomously displace the robot to the desire coordinates

3. Concerns (selection criteria)  Size and weight of user interface  User friendly  Number of features it can have  Maximum signal range   Adaptability to add-ons and features   Programming language with PC104

4. Concept #1  Tethered Laptop ProsPros  Adaptable to future programs and control modules  Full featured  Complex functionality  inexpensive ConsCons  Limited distance  Not ergonomic

5. Concept #2  Wireless Remote ProsPros  Light weight  User friendly  Long operating range ConsCons  Expensive transceiver modules  Limited functionality

6. Preliminary Analysis

7. Conclusion Software concepts decision will be determined after an optimal solution for the user interface unit is tested and determined Using a wireless keyboard as the communication interface could also be feasible. Cost less and more feature than remote Wireless capability Lighter weight than a laptop
