Mission Profile - WOCCS Team
Mission Statement
The WOCCS System is designed to wirelessly transmit command data from a base station to a remote unit at both a mid and long range distance. The remote unit receives the command, perform the function, and collect telemetry data via USB to transmit back to the base station PC.
Duty Cycles of RF
One usage of the WOCCS unit includes powering on unit, attaching to remote unit, and transmitting/receiving up to 56 kbps of command and telemetry data for the maximum time usage of 2 hours, powering off unit, and leaving it in idle state for recharge for 30 minutes.
Duty Cycles / Typical Mission / Marginal Test Limit / Target Test LimitTypical Mission Length / 10 minutes / 0-15 minutes / 0-30 min
Maximum Mission Length / 30 minutes / 1.5 hours / 2 hours
# Usage Times / Day (in succession) / 1 (10 min use) / 2 (2 hour use) / 4 (2 hour use)

% in Idle / 80% / 75% / 70%
Recharge Time / N/A / .75 hours / 0.5 hours
*Typical Mission will not need batteries recharged. Recharging occurs after 2 hours of use
Data Transfer
The WOCCS System is primarily transmitting and receiving simplistic command data to control the LV One Platform. Commands may include moving the robot forward, backward, or directional. The WOCCS System will also be able to collect basic telemetry data such as temperature and relative humidity from the remote unit and transmit data back to base station.

Mid-Range Environment Conditions
The WOCCS Unit will be primarily used in indoor conditions, specifically in the SLC field house. The surface the unit will attach to will primarily be the LV One Platform. This robot is used in design competitions demonstrating the robots ability to interpret control signals and return telemetry data to a base unit. The robot will be operating on hard, flat surface such as tile, a mat, or track.

Long Range Environmental Conditions
The long range team will be using the robot in outside conditioned, permitting weather conditions are ideal. A typical mission consists of transmitting and receiving the same data as the mid-range in an external temperature such as RIT’s parking lot. Ideal weather conditions include lack of precipitation, snow, storms, lightening, or outside all environment ranges specified below.

Physical Obstructions
WOCCS will be attachable to the LV One Platform. Physical obstructions include the motor controller, wheels, external base, and circuitry the robot uses. During the senior design mission, obstacles may include walls, bumps in ground (not exceeding 1 inch), and other walled structures that the competition may include. The WOCCS unit will be designed to transmit and receive signals in a room or outside environment that is assumed to have little or no frequency interference caused by obstacles.

Other Competition Units Interference / Possible / Possible / Possible
Walls - Interference / Yes / Yes / Yes
Surface Variation / 0-1 inch / 0-2 inch / 0-3 inch

*Interference mediums will be determined based on the FCC Medium Interference Regulations. Multiple units will be able to operate using the same frequency.
