Haptic Syringe Simulator Development
Budget: ₹600 – ₹1,500 INR
We are looking for an experienced developer or small team to build a proof-of-concept 1-DOF haptic syringe simulator for anaesthesia training.
The goal is to allow a user to push a physical syringe and feel changing resistance as the virtual needle passes through skin, fat, muscle, and finally bone. A simple 3D visualization should display the needle moving through these tissue layers with realistic PBR textures.
Scope of Work
Hardware
Design and build a custom 1-DOF haptic syringe device
Select and integrate suitable motor, driver, controller, and sensors
Develop firmware for real-time force feedback
Ensure smooth, responsive haptic performance
Software
Develop in Unity (preferred), Unreal Engine, or native C++
Real-time communication between hardware and software
Map insertion depth to programmable force feedback
Implement editable force curves using a text/configuration file
Create a simple calibration interface
Graphics
Moderate-detail 3D scene
Tissue layers:
Skin
Fat
Muscle
Bone
Realistic PBR textures
Needle insertion visualization
Deliverables
Complete source code
Unity/Unreal project (or native C++)
Firmware source code
CAD files (if applicable)
Electronics schematics
Bill of Materials (BOM)
Motor and sensor specifications
Calibration utility
Documentation and build instructions
Editable force configuration file
Timeline
Prototype to be completed within 2 weeks.
Before Applying
Please include:
Examples of similar robotics, embedded, haptic, or simulation projects
Experience with motors, encoders, sensors, and embedded systems
Your preferred development platform (Unity/Unreal/C++)
Estimated hardware components you would use
Confirmation that you will provide complete source code and documentation
Questions to Answer
How would you implement the haptic feedback?
Which motor and sensing method would you recommend?
Have you built any force-feedback or haptic systems before?
Can you complete both hardware and software within two weeks?
What hardware architecture would you propose for this project?
