Technical & Management Proposal

Introduction

Purpose of the document

The purpose of this document is to raise Orion Team’s willingness to participate in European Rover Challenge 2020. Thus, the document provides an analysis of ERC requirements and proposes a solution, which is a complete Mars rover. Moreover, it presents a management methodology and expected time and financial costs.

Scope of the document

The document has been divided into three main chapters:
  1. Technical Proposal
  2. Management Proposal
  3. Time And Financial Costs Proposal

The document is meant to draft an overall process to design, construct and manage the interplanetary, Mars rover project that is to be undertaken by the Orion Team.

Proposed solution

ADD STUFF AND PICTURES, LOTS AND LOTS OF PICTURES WHEN I GET THEM

  • Mechanical solution

Our rover solution is based on a four wheeled chassis divided longitudinally into two sections connected by a free axle. The front section will be a base for the arm. The back section will house the main computer, measurement equipment, networking and batteries. The RF antenna, emergency power button and indicator light will be mounted on a straight vertical mast no higher than one meter. The arm and the manipulator will include six separate axes of movement, including one for rotation of the whole assembly, two to drive first and second stages and three for the manipulator.

The chassis propulsion will consist of four BLDC motors and motor drivers from hoverboards. The motors and drivers are rated 36V 10A. This solution is self-contained, provides simple maintenance, high efficiency due to the lack of gearing, is easily replacable and offers significant torque.

Schedule and deliveries

Schedule
Milestone ID Name Time Description
SCH-MLST-0010 Milestone 1: Chassis \(T_0\) + 2 months By the end of the milestone the rover shall move freely and reliably as a remotely controlled vehicle. Software shall be capable of registering logs, including power consumption and angular velocities of each wheels. A preliminary PID controller for each wheel shall be implemented.
SCH-MLST-0020 Milestone 2: Manipulator \(T_0\) + 4 months The rover shall be equipped with a fully functional manipulator, capable of grasping objects and operate safely and reliably. The ground control shall retrieve feedback data such as position of each of robotic arm segments, crushing strength of the gripper. A basic automation, e.g. deploying an arm into an initial operation position, shall be implemented.
SCH-MLST-0030 Milestone 3: Science, collection, maintenance tasks \(T_0\) + 6 months The rover shall be able to store specimens samples and perform basic scientific trials. The rover shall be also to collect a cache object fulfiling the requirements. The rover shall be able to all defined 3 tasks with a user intervention. Rover automation shall be improved to the degree some manipulation operations will be done automatically such as approaching to an object. The rover shall be able to recognize, categorize and label basic maintenance-related objects.
SCH-MLST-0040 Milestone 3: Autonomy task \(T_0\) + 8 months The rover shall be able to traverse the terrain in a semi-autonomous manner. Path routing and hazard categorization based on simple conditions shall be implemented. The rover shall traverse automatically a designated path, without obstacle finding abilities. The Team shall have a solid basis and undestanding in using IMU and VO to further improve autonomy.
SCH-MLST-0050 Milestone 3: Autonomy task \(T_0\) + 11 months The rover shall be a well equipped robotic platform capable of performing several geological task, help an astronaut, collect cache objects and traverse terrain in at least semi-automated manner. All tests defined in VTP shall be successfully completed.
