Rover Level 1 Requirements
By Maxwell Nguyen
Level 1 Requirements:
Our top mission requirements are derived from the specifications of the standard Arxterra Rosco. The requirements will include speed, power consumption, cost, and time.
Speed:
Our rover is expected to move at a speed of 0.200277 m/s. This is calculated using the standard wheel diameter of 45mm and RPM of the motor.
Wheel diameter = 45 mm
3D model of wheel
Motor Specs:
120:1 Plastic Gearmotor 90-Degree Output
Free-run speed @ 6V: 85 rpm
Velocity calculation:
Radius = d/2
R = 0.045/2
R = 0.0225 mm
Circumference = 2*pi*r
C = 2*pi*0.0225
C = 0.141372 m
Velocity = RPM*C
V = (85 rot * 0.141372 m)/60 sec
V = 0.200277 m/s
Cost:
Must have a lower cost compared to the standard RoSco of $284.13. The BOM for the standard RoSco can be found in the two links below. The first one lists the parts and links to find the parts while the second link provides a sum of all the costs of each part.
Parts list and where to purchase them.
Time:
The rover must be completed by May 12. This takes into account CSULB’s final exam schedule and deadline for the project.
