Precision in Motion: Advancing Medical Devices Through Robotics

Robotics Transforming the Future of MedTech.

In the past decade, robotics has moved from research labs to operating rooms, rehabilitation centers, and diagnostic suites. Robotics enables minimally invasive procedures, precision in motion, automation of repetitive tasks, and assistive technologies that restore independence. 

Yet, for medical device innovators, integrating robotics into a clinical environment brings formidable challenges. Robotics must be safe, reliable, intuitive for clinicians, and compliant with strict regulatory standards. Devices must operate with exacting accuracy and repeatability — where even small errors could compromise patient outcomes. 

At Boston Engineering, our Robotics Center of Excellence (COE) delivers the expertise to meet these challenges. By combining robotics with our broader systems engineering discipline, we create devices that integrate mechanics, electronics, software, and human-centered design into solutions that improve care and transform possibilities for patients.

The focus and discipline of DFX is a powerful tool if used as part of a broader strategic approach to developing product/process differentiation, and a sustainable advantage against competition. Involve Design for X in Strategy. Once your team has determined the focus of your strategy, place the focus of design on developing competitive advantage. 

At Boston Engineering, DFX is a core part of creating values during our product development process. We focus on several key DFX areas that align with our expertise:

• Design for Manufacturability (DFM)
• Design for Assembly (DFA)
• Design for Cost (DFC)
• Design for Testability (DFT)
• Design for Reliability (DFR)
• Design for Serviceability/Maintainability (DFS)
• Design for Usability (DFU)
• Design for Modularity (DFMo)

The Challenge: Precision, Safety, and Usability  

Medical robotics is one of the most demanding fields in product development. Each system must not only perform with accuracy but also integrate into the clinician’s workflow and meet the highest safety standards. 

Some of the most common challenges include: 

• Precision of motion: Surgical and diagnostic robots require micrometer-level accuracy to ensure consistent outcomes. 

• Safety interlocks: Devices must include redundancies and fail-safes to protect patients and clinicians in every possible scenario. 

• Human–machine interaction: Interfaces must be designed so clinicians can operate advanced robotic systems intuitively, even under pressure. 

• Sterility and usability: Robotic components must be compatible with sterile environments and designed for quick setup and cleaning. 

• Integration with hospital systems: Robotics must work seamlessly within broader ecosystems of imaging, monitoring, and data management. 

Our Approach: Robotics Powered by Systems Engineering 

Boston Engineering’s Robotics COE focuses on precision, control, and safety while embedding robotics within the broader medical device system. Through our systems engineering approach, we ensure robotics isn’t an isolated feature but a well-integrated element of the device architecture. 

Key capabilities include: 

• Mechatronics and kinematics: Designing robotic mechanisms that deliver repeatable, precise motion while minimizing mechanical complexity. 

• Control systems integration: Applying expertise in sensors, actuators, and control loops to ensure accuracy, responsiveness, and safety. 

• Embedded intelligence: Developing custom firmware and electronics to manage robotic performance while minimizing latency and power consumption. 

• Human factors engineering: Creating clinician-centered interfaces that make complex robotic systems intuitive to use. 

• Compliance-focused design: Embedding safety redundancies and documentation aligned with FDA and IEC standards. 
  

Device Examples: Robotics in Action 

Boston Engineering has applied robotics to a wide range of medical technologies, including: 

• Robotic-assisted surgical instruments that enhance precision in minimally invasive procedures. 

• Automated laboratory systems that accelerate sample preparation and analysis with consistency. 

• Rehabilitation and assistive robotics that restore mobility and independence for patients with physical limitations. 

• Micro-robotics for diagnostics that manipulate small samples or instruments in compact devices.

Case Study: Enhancing Independence Through Assistive Robotics 

A medical innovator approached Boston Engineering to develop a robotic assistive device for patients with severe mobility impairments. The goal was to create a system that restored independence in performing daily activities while ensuring safety, reliability, and ease of use. 

Our role: 

• We designed the robotic architecture to balance strength and precision, ensuring smooth, repeatable motion. 
• Our Control Systems COE implemented advanced sensing and feedback loops to enable responsive, adaptive motion control. 
• Human factors specialists worked closely with clinicians and patients to create a simple, intuitive interface that minimized learning curves. 
• Our Design for X COE ensured the device could be manufactured cost-effectively and maintained in real-world settings.

• The device delivered significantly improved usability and safety, empowering patients to perform tasks independently. 
• Clinicians reported smoother integration into rehabilitation programs.
• The design provided a foundation for future product iterations, demonstrating scalability and adaptability. 

Broader Results: What Robotics Delivers in MedTech 

Across projects, Boston Engineering’s Robotics COE has enabled innovators to achieve: 

• Increased surgical precision through robotic-assisted tools that reduce variability and enhance outcomes. 

• Faster lab workflows by automating repetitive sample handling tasks. 

• Improved patient quality of life with assistive devices designed for safety and independence. 

• Regulatory-ready solutions by embedding compliance and safety documentation from the beginning. 

Robotics as a Driver of Innovation 

Robotics is more than a technical capability — it’s a driver of transformation in healthcare. By combining the precision and adaptability of robotics with the discipline of systems engineering, Boston Engineering helps innovators bring breakthrough devices to life.
