[ 01 / FEATURED CASE STUDIES ]
Four deep-dive projects that show how 4TECH Engineering approaches measurement, motion, control and connected systems.
Browse all 15 systems belowAutomated angular scanning and RF data acquisition for antenna pattern analysis.
Radiation patterns depend on the measurement environment, reference source and calibration procedure. No numerical gain accuracy or certified frequency coverage is specified here.
Mechanical design and computational kinematics for coordinated robotic manipulation.
Degrees of freedom refer to the corresponding assembly or model. Payload ratings, positioning tolerance and comparative solver performance are not quantified in this portfolio.
A compact controller architecture integrating processing, sensing, motor drive and battery power.
Project completion does not imply a manufacturing release, certified airworthiness or a specific flight envelope. Fabrication and flight decisions require their own applicable checks.
Multi-sensor data acquisition and a web interface for environmental monitoring experiments.
This is an engineering monitoring project, not a certified life-safety instrument. Sensor values alone do not establish whether a confined space is safe to enter.
