Pass / Fail Criteria: LVE is operational at a distance of at least 200 feet

Observed Range of operation: ______156______ft Result: Pass / FailX

Possible Reason for failure: For this test the WOCCS was powered using the USB connection on a laptop. This limits the amount of power that the WOCCS board is able to draw and may be the reason the test was failed. WOCCS teams doing similar tests but using an independent power supply were able to achieve much greater communication range

Test T5: Number of I/O Inputs

Objective

Engineering Specs Tested: ES5

This is an observational exercise to demonstrate that the Controls system has more than 6 I/O interfaces.

From the Arduino home page you can find the following data sheet for the Arduino Nano development board that was used in the controls system.

As stated there are 14 Digital I/O pins with 6 PWM pins. This means the board meets engineering spec 5.

Test T6: Exposed wires without insulation

Objective

Engineering Specs Tested: ES9

This is an observational exercise to demonstrate that there are no exposed wires without insulation.

The following picture is of the Controls and MSA boards in the chassis fully wired. As shown there are no exposed wires that are not properly insulated.

Test T7: No perceivable latency

Objective

Engineering Specs Tested: ES18

This is an observational exercise to demonstrate that the LVE operates without any latency.

Through testing of the LVE it is clear that there is no noticeable latency. The robot quickly responds to all commands made by the user allowing for easy and accurate use of the LVE and the MSA.
