A Dexterous Robotic Hand Design Project• The project focuses on designing a teleoperated robotic hand system with haptic feedback that will be placed in radioactive environments so that operators can handle substances remotely.• Designed encoder(via SPI), microcontroller(ARM Cortex-M7), and motor driver(gate driver with integrated FETs) PCBs for a teleoperated robotic hand system.• Scripted C++ libraries for brushless direct current motor (BLDC) field-oriented control (FOC) control using space vector pulse width modulation (SVPWM), inter-board communication (SPI, CAN), and PID torque/current control.• Soldered SMD devices for prototype boards, made wiring harnesses for inter-board connections, and tested signal integrity using oscilloscopes and multimeters, achieving expected behaviors.• Soldered SMD devices for prototype boards and made wiring harnesses.

• Designed and implemented the auto-test platform based on TestComplete and Machine Expert to perform hardware verifications. Spent over 500 hours of tests on the latest beta products with promising results. Constructed complicated test circuits by using jump wire between PLCs and test computer.• Used Jenkins and Jira to construct an automated database for uploading test results.

• Designed auto-test platform via Python by sourcing and testing Robot Framework source codes.• A brief introduction to Modbus TCP and some basic practices on Modbus protocols.
