I’m Janmesh Patel, a robotics software engineer in New Jersey. I work on perception, planning, control and the hardware they run on, mostly in C++17, Python, ROS 2 and Linux.
Numbers I measured on my projects and at work.
| Parameter | Conditions | Value | Unit | Ref. |
|---|---|---|---|---|
| Control-loop rate | Franka teleop on Jetson Orin Nano | 100 | Hz | No. 01 |
| Camera → arm latency | p50 / p95 | 65 / 117 | ms | No. 01 |
| Control-loop period | p99, logged sessions | 10.1 | ms | No. 01 |
| Loop overruns | across logged sessions | 0 | No. 01 | |
| Command → motion | p50, after network fix and drive retune | 158 → 30 | ms | No. 01 |
| Median recoveries | terrain-aware vs default Nav2 | 20 → 3 | No. 02 | |
| Route time | terrain-aware vs default Nav2 | 318 → 113 | s | No. 02 |
| Assembly tolerance | PCB and electromechanical assembly, Clearpath | ±0.0762 | mm | |
| Competition wins | Robocon, national finals | 50+ |
The problem, what I built, and the results for each one.
I built a 100 Hz teleoperation system that drives a simulated Franka arm from a tracked marker, running on a Jetson Orin Nano and Isaac Sim. The goal was low latency, and safe behavior when the network or robot state goes bad.
| Metric | Before | After | Unit |
|---|---|---|---|
| Command → motion, p50 | 158 | 30 | ms |
| Average ping | 43.4 | 0.35 | ms |
I wrote a Nav2 costmap layer that scores terrain from 3D LiDAR by slope, roughness and step height. Alongside it I built a vehicle safety arbiter and a simulated CAN drive interface that supports fault injection.
| Metric | Before | After | Unit |
|---|---|---|---|
| Median recoveries | 20 | 3 | |
| Route time | 318 | 113 | s |

Founder · Robotics R&D
My own self-funded R&D company. I work on autonomous ground vehicle concepts in Isaac Sim, covering navigation risk, motion planning and system testing. I also design the PCBs, bring up the boards and integrate the Jetson Orin Nano.
Professional development
Hands-on STM32/FreeRTOS and Embedded Linux projects: multitasking, SPI + DMA logging, telemetry, profiling, pthreads, PWM, signals and state machines.
Robotics Specialist & R&D Technician
Tested and debugged autonomous mobile robots running ROS 2 on Linux, tracking faults through software, firmware, comms, sensors, power and hardware. On the Husky A300 I integrated LiDAR, cameras, long-range Wi-Fi/LTE and wireless charging, and calibrated the LiDAR. I assembled parts to ±0.0762 mm and made assembly 50% faster with new tooling.
Electronics & Programming Head · Robocon integration lead
Led firmware and electronics for a team of 10+, using STM32, Arduino, Raspberry Pi and custom PCBs. We reached the Robocon national finals and won 50+ competitions.
