Study and Improvement of a Mobile Robot's Design: Improving Maintenance and Component Accessibility

Track

Production

Description

At Enova Robotics, field mobile robots incorporate numerous subsystems, including drive systems, batteries, control electronics, sensors, and vision systems. In the current design, the robot's compartments are difficult to access, resulting in longer maintenance and troubleshooting operations.

The project addresses how the robot's mechanical architecture can be redesigned to ensure that all maintenance points are quickly and safely accessible, without requiring extensive disassembly or compromising the overall protection and robustness of the system.

Objective

Modify the robot's design to make all maintenance points easily accessible, simplify maintenance operations, and reduce intervention time.

Proposed tasks

• Audit: Analyse the current architecture and identify components requiring regular maintenance, including batteries, electronics, connectors, motors, and sensors.
• Diagnosis: Identify hard-to-access compartments and obstacles encountered during maintenance operations.
• Design: Propose solutions such as removable covers and access panels, quick-release fasteners, component repositioning, and modular design.
• Modelling: Model the proposed modifications using 3D CAD software and verify clearances, structural rigidity, sealing, and integration.
• Validation: Prepare the technical documentation and a validation prototype or mock-up, including a before-and-after comparison.

Relevant skills

• Mechanical design and CAD, such as SolidWorks or equivalent.
• Technical drawing.
• Electromechanics.
• Maintenance methods.
• Functional analysis.
• Technical documentation.

Expected deliverables

• Technical study report.
• CAD models and technical drawings of the redesigned architecture.
• Simplified maintenance and access guide.
• Validation prototype or mock-up.
