...

• At a minimum, the arm has 4 degrees of freedom

• Max weight 15kg.

• The arm can pick up a 5kg object and hold the object

• Able to adjust rover center of mass after picking up heavy object

• Able to reach at least a workspace and pick up the end effect module

• Able to grab a handle, flip a switch, and push a button

...

The science system is designed with the following requirements:

• Max weight 15kg

• Able to dig the hole and extract soil

• Able to perform onboard analysis (software analysis or chemical analysis)

• Able to seal the sample and transport the sample back

Autonomy

Autonomy is a complete system itself but requires the communicate with the drivetrain system actually to control the rover. Note: The drivetrain control is abstracted away from the autonomy system and only exposes certain APIs for motion control.

...

The autonomy system is designed with the following requirements:

• Able to navigate through the area based on the given GPS coordinate

• Accurate GPS Coordinate information(VN300 is capable of providing the accuracy)

• Camera ability to detect AR tags and objects

• Camera ability to avoid large obstacles.

Power

The power system is available to protect the other electrical components onboard when one component fails and to deliver the required power to all the components. The system expands as the rover develops.

The power system is designed with the following requirements:

• The power system takes 48v from the battery

• The power system monitors all the rails before delivering the power to the rest of the system

• The power system is able to detect faulty rails and disable them to ensure the safety of other components

• Safety switch to kill the rover under emergency

Communication

The current rover communication system is equipped with a 27dbm telemetry radio operating at 900 MHz.

The communication system is designed with the following requirements:

• Able to reach beyond the line of sight for a 1 km

• Support enough bandwidth for live video feed

• Switch over to a backup link in cases main link failure

• Reliable gimbal system and relay the video feed directly back to ground station

• Radio links need to be available for at least rover three orientations:

  • Two sides facing the ground station

  • the back side facing the ground station

Rover Vehicle Design:

When our team tried to attend URC for the last two seasons, most parts of the rover, especially mechanical, had already been designed. Therefore, this year's Rover Vehicle Design focuses not on recreating the whole rover but on validating the current design, making necessary improvements, and integrating the system to make it work. The following is the breakdown of the detailed vehicle design architecture decisions our Our team will make continue discussing to ensure the final productvehicle design matches the competition's successrequirements.

Note: the timeline is subject to change. As highlighted in the diagram, the team's goal is to complete the whole rover system as soon as possible, test it, and optimize it for the competition, which aligns with the iterative design process.
