Industrial robots, custom machinery and automation.
I design industrial machines and robots and follow them through fabrication, assembly and commissioning, until they are delivered and working. MSc in Applied Design, Sharif University of Technology.
I'm Hassan Nasiri Khonsari, a mechanical and mechatronics design engineer with an MSc in Applied Design from Sharif University of Technology. I design custom machinery and industrial robots, and I don't stop at drawings: I follow fabrication, assembly and commissioning until the machine works.
I led the mechanical design of Iran National Post's postal sorting robots across three generations: 80 robots from the first two generations run in the Tehran and Kermanshah distribution centers, and the third generation went into production as a 200-unit series. My knee prosthesis constraint and stability test apparatus — the first of its kind in Iran — won 2nd place at the Khwarizmi Youth Award and was selected at the 64th Alborz Prize.
Design and build, batch production and consulting — each backed by a real machine that was built and works.
Need a machine that isn't on the market, or whose foreign equivalent is expensive and out of reach? I design it from concept and calculations to manufacturing drawings, and follow fabrication, assembly and commissioning through to delivery.
Design and build of mobile robot fleets for sorting and moving loads in warehouses and distribution centers, and of service robots — from chassis and drive system to load mechanisms and preparation for batch production. 280 postal sorting robots across three generations came out of this work.
If you need industrial parts in batches and want them delivered with an engineering-driven, professional process and quality control: drawing review and GD&T, choice of manufacturing method, management of machining and fabrication workshops, and dimensional and weld inspection. More than 8,000 industrial parts have been delivered this way so far.
Automation architecture, PLC programming (Delta and Siemens), HMI design and motion control — for a new machine or to upgrade one you already have.
Standards-based test rigs for labs, universities and medical device makers — such as the knee prosthesis tester built to ASTM F1223, and a friction test rig whose data led to a paper in Scientific Reports.
Turning a prototype into a product that can be made cheaper, faster and with consistent quality. In the third-generation postal sorting robot, weight dropped from about 30 to 10 kg, speed rose from 1.1 to 1.8 m/s, and the footprint shrank from 70×70 to 55×55 cm.

Iran's first postal sorting robot of its type: 80 robots in Tehran and Kermanshah, and a 200-unit third generation.
Six-DOF testing of total knee replacements per ASTM F1223 — the first apparatus of its kind in Iran.
Five machines, from 200×200×150 mm up to 500×500×400 mm with ball screws and industrial linear rails.
A CNC for wood and light metals that becomes a large 3D printer with a head change.
A fleet of seven waiter robots — Iran's first waiter robot of its type.
A platform for mobile service robots: the ROS-based Kach and the omnidirectional, mecanum-wheeled Karnak.
One of 12 laureates in the Technologists & Inventors category, for the knee prosthesis constraint and stability test apparatus; also honored by Sharif University of Technology with its silver medal — 2026.
For the mechanical design of postal sorting robots — 2025.
For the knee prosthesis constraint and stability test apparatus, with a UNESCO certificate and recognition by the President — 2023.
An interview with Hassan Nasiri Khonsari, MSc graduate in mechanical engineering from Sharif University of Technology and Alborz Prize laureate, on designing and building machines and mechatronic systems — from an idea to a working machine.
On the university’s main website ↗Hassan Nasiri Khonsari, a Sharif University of Technology graduate named among the laureates of the 64th Alborz Prize in the Technologists & Inventors category, was honored at a meeting of the university’s board and presented with a certificate of appreciation and a silver medal minted by Sharif University.
The full award ceremony, from the Alborz Foundation’s channel, including a short conversation about the experiences that shaped his academic and professional path, the Alborz Prize as a publicly supported award, and the role of donors in supporting science and research. International Conference Hall, Shahid Beheshti University.
A video screened at the 26th Khwarizmi Youth Award ceremony in the presence of the President, where the project won 2nd place in the applied designs category. Hassan Nasiri Khonsari, mechanical designer of generations one to three, explains the improvements in the third generation: speed raised from 1.1 to 1.8 m/s, weight cut from about 30 to 10 kg, footprint reduced from 70×70 to 55×55 cm, and a two-level structure.
