Application

Design takeaway

Embrace collaborative design and modularity to create robots that are both high-performing and practical for ongoing development and experimentation.

How to apply

When developing complex robotic systems, actively involve mechanical, electrical, and software engineers, as well as potential end-users, from the outset. Prioritize designs that allow for rapid iteration and repair, perhaps by specifying components that can be 3D printed or easily sourced.

Project actions

  • 01Consider who else needs to be involved in your design process to bring different skills.
  • 02Think about how your design could be easily repaired or updated if something goes wrong.

Method & Evidence

AimHow can co-design principles be applied to develop legged robots with enhanced dynamic movement capabilities and improved repairability?
MethodCase Study / Collaborative Design
ProcedureThe Gepetto team at LAAS, in collaboration with the Max Plank Institute, developed two prototype quadruped robots. This involved integrating miniature, vector-controlled brushless motors with low-profile gearboxes to achieve reversible actuation and high torque densities, enabling dynamic movements. The design also prioritized the use of 3D-printed parts for easy repair.

Strengths & Limitations

Strengths

  • +Demonstrates a practical application of co-design in a cutting-edge field.
  • +Highlights tangible benefits in performance and maintenance.

Limitations

The specific technologies and expertise mentioned might not be universally accessible. The focus is on research prototypes, not mass-produced consumer goods.

Reliability & validity

The findings are based on the development of specific prototypes, making direct generalization challenging. The 'success' is demonstrated through the capabilities of the developed robots, implying a form of functional validity.

Think critically

To what extent does the 'fragility' of current systems drive innovation, and could over-engineering for repairability compromise initial performance?

05

Design Principles

"Interdisciplinary co-design and modular repairability are crucial for advancing robotic capabilities and practicality."

This approach highlights how interdisciplinary collaboration can overcome limitations in existing robotic systems, enabling more advanced functionalities. The incorporation of readily repairable parts also addresses practical concerns in research and development, reducing downtime and cost.

What This Means for Your Design

Working together with different experts and making parts easy to replace (like with 3D printing) helps create better, more dynamic robots that are less of a headache to fix.

How to use in your project

  • 1.Reference this study when discussing the benefits of interdisciplinary collaboration in your design process.
  • 2.Use the findings on 3D-printed parts to justify your own design choices for repairability or modularity.
