Mechanical Design Engineer

About Plebc Innovations Pvt. Ltd.

Plebc Innovations is developing TORUS, a cutting-edge Tele-Operated Robotic Ultrasound System (TRL-4) that enables radiologists to perform ultrasound procedures remotely. The system integrates robotic manipulation, haptic feedback, precision actuation, and medical-grade safety mechanisms to expand diagnostic access across India and globally. Mechanical engineers play a pivotal role in designing the 7-DOF robotic arm, probe manipulation systems, gantry systems, pressure-actuation modules, and safety mechanisms described in the product concept .

Role Overview

As a Mechanical Design Engineer, you will contribute to the design, development, analysis, prototyping, and testing of robotic mechanical subsystems used in TORUS. You will work closely with robotics, electronics, and software teams to build safe, precise, and reliable mechanisms aligned with medical device safety standards.

This role is ideal for candidates passionate about robotics, medical devices, and precision mechanisms.

Key Responsibilities1. Mechanical Design & CAD Modelling

• Develop 3D CAD models and 2D manufacturing drawings
• Haptic curved pad designs and phantom probe housings
• Design enclosures, linkages, brackets, and precision components per product requirements .
• Ensure manufacturability (DFM) and assembly feasibility (DFA).

2. Mechanical Analysis & Engineering Calculations

• Perform structural, kinematic, and dynamic analysis of robot linkages.
• Evaluate forces, torques, stiffness, and stress levels for patient-safety-critical components (e.g., pressure actuator limit of 70 N) .
• Support FEA simulation (ANSYS/SolidWorks Simulation/ Fusion 360).

3. Prototyping & Testing

• Build and validate prototypes
• Support integration with sensors and actuators (pressure sensors, motors, IMUs) .
• Conduct mechanical endurance, accuracy, and safety tests.

4. Collaboration & System Integration

• Work with robotics engineers for inverse kinematics & control compatibility.
• Support integration with electronics (motor drivers, power management modules).
• Participate in testing of remote control movements, latency behaviour, and safety constraints .

5. Documentation & Compliance

• Prepare design documents, test reports, BOMs, and revision histories.
• Support engineering documentation
• Risk management (ISO 14971)
• Maintain clear mechanical safety documentation (collision detection, max-pressure limits, emergency controls) .
