Run it in the cloud when the model is too large for the device and the answer can wait for the network. Many systems do both: fast decisions on the device, heavy work on a server. https://www.whitehatdesignstudio.com/guides/how-drone-detection-works/https://www.whitehatdesignstudio.com/guides/how-drone-detection-works/Sat, 07 Nov 2026 04:00:00 GMTGuidesDrone detection finds a drone with one or more sensors: radar, a radio receiver, microphones or a camera. Each one has a blind spot, so the strongest systems combine them. A camera system such as SKYLOCK runs a detection model on every frame, predicts where the drone is going and turns a gimbal to keep it in view. https://www.whitehatdesignstudio.com/guides/digital-quality-inspection/https://www.whitehatdesignstudio.com/guides/digital-quality-inspection/Sat, 07 Nov 2026 04:00:00 GMTGuidesRecord each defect where it is found, by the person who found it, on a screen that takes no longer than the paper form. Give every item one of three outcomes: accepted, rework or rejected. Then the dashboard, the audit log and the reports all come from that one record. https://www.whitehatdesignstudio.com/guides/prototype-to-product/https://www.whitehatdesignstudio.com/guides/prototype-to-product/Sat, 07 Nov 2026 04:00:00 GMTGuidesDefine what working means, in numbers with their conditions. Build the riskiest part first and test it where it will be used. Then design for manufacture and prove the product in three builds: engineering, design and production. A prototype proves an idea once. A product has to work every time, for people who never met the engineer. https://www.whitehatdesignstudio.com/guides/verify-a-company-in-pakistan/https://www.whitehatdesignstudio.com/guides/verify-a-company-in-pakistan/Sat, 07 Nov 2026 04:00:00 GMTGuidesAsk for the company's registered name and its incorporation number, check them on the SECP's public company search, and check its tax number on the FBR's Active Taxpayer List. For engineering or public sector work, ask for any Pakistan Engineering Council or EPADS registration. Then ask to see work you can check is real. https://www.whitehatdesignstudio.com/guides/stm32-vs-esp32/https://www.whitehatdesignstudio.com/guides/stm32-vs-esp32/Sat, 07 Nov 2026 04:00:00 GMTGuidesUse an ESP32 when the product's main job is to connect, because Wi-Fi and Bluetooth come on the chip. Use an STM32 when its main job is to control something on an exact schedule, such as a motor. When a product needs both, use one of each and join them with a serial link. https://www.whitehatdesignstudio.com/guides/visual-slam-vs-lidar-slam/https://www.whitehatdesignstudio.com/guides/visual-slam-vs-lidar-slam/Sat, 07 Nov 2026 04:00:00 GMTGuidesSLAM lets a robot build a map and work out where it is on that map at the same time. Visual SLAM does it with cameras, which cost less and see detail but need light and texture. LiDAR SLAM does it with a laser scanner, which measures distance directly but costs more and can miss glass. https://www.whitehatdesignstudio.com/guides/what-to-automate-with-ai/https://www.whitehatdesignstudio.com/guides/what-to-automate-with-ai/Sat, 07 Nov 2026 04:00:00 GMTGuidesAutomate work with a clear input, a repeatable result and a way to check it: reading an enquiry, filing a document, writing a routine report. Keep a person on anything that is costly to get wrong. Start with one task, test it on your own messages and documents, and look hard at what it gets wrong. https://www.whitehatdesignstudio.com/guides/vision-model-lab-to-field/https://www.whitehatdesignstudio.com/guides/vision-model-lab-to-field/Sat, 07 Nov 2026 04:00:00 GMTGuidesA vision model learns from the pictures it was trained on, so its accuracy falls when the light, the camera, the angle or the place changes. Researchers call this distribution shift. The answer is to collect pictures from where the model will run, test on those, and give every accuracy figure with the conditions it was measured in. https://www.whitehatdesignstudio.com/work/tree-planting-robot/https://www.whitehatdesignstudio.com/work/tree-planting-robot/Thu, 05 Nov 2026 04:00:00 GMTCase studiesA competition robot that follows a grid of lines, works out where to plant and places tree-marked blocks, built for NERC between September 2023 and April 2024. https://www.whitehatdesignstudio.com/work/auto-vendi/https://www.whitehatdesignstudio.com/work/auto-vendi/Thu, 05 Nov 2026 04:00:00 GMTCase studiesA delivery robot that takes an order from a phone app, drives itself through the building and brings a locked compartment to the person who ordered, who releases it from the app. https://www.whitehatdesignstudio.com/work/harp/https://www.whitehatdesignstudio.com/work/harp/Thu, 05 Nov 2026 04:00:00 GMTCase studiesA humanoid robot that finds its own way through a building, turns to face the person in front of it and holds a conversation on its own onboard computer. https://www.whitehatdesignstudio.com/work/quality-inspection-platform/https://www.whitehatdesignstudio.com/work/quality-inspection-platform/Thu, 05 Nov 2026 04:00:00 GMTCase studiesA system for logging defects on the factory floor, with dashboards for managers and an admin portal for the people who run the line. https://www.whitehatdesignstudio.com/work/reflex/https://www.whitehatdesignstudio.com/work/reflex/Thu, 05 Nov 2026 04:00:00 GMTCase studiesA research prototype of a prosthetic hand that starts moving on the wearer's muscle signal and uses a camera in the palm to choose the grip. https://www.whitehatdesignstudio.com/work/scenescribe/https://www.whitehatdesignstudio.com/work/scenescribe/Thu, 05 Nov 2026 04:00:00 GMTCase studiesA headset and a cane that answer a spoken question about what is in front of the wearer, built for people with visual impairments. https://www.whitehatdesignstudio.com/work/skylock/https://www.whitehatdesignstudio.com/work/skylock/Thu, 05 Nov 2026 04:00:00 GMTCase studiesA ground control station that finds drones in live camera feeds and turns a camera gimbal to keep them in view, first steered by an operator and then on its own.
