Power Exoskeleton for Motion Recording and Reproducing                           

• Designed a power suit that records angular configurations of the shoulder joint when a person demonstrates motions, then users can wear it to reproduce the recorded motions. Its main purpose is to increase the accuracy and efficiency of shoulder rehabilitation.

• Designed it with 3 revolute joints to synthesize 3-DOF rotational motions of the spherical joint (shoulder joint) with Euler-angles convention, and equipped each axis with a rotary encoder for recording data, drivetrain mechanisms for actuating, and safety clutch mechanisms for disengagement. 

• Designed kinematic mechanisms, mechanical components, and transmission drives.

EUROBOT  World  Cup                                                                           ​

• Designed and built two autonomous robots to complete several specific tasks.

• Designed the chassis powertrain and task mechanisms of the robots.

• Derived kinematic and dynamic equations of the powertrain to evaluate how to optimize the integration of our mobile robots. 

• Leader of Mechanical Design Group.

T-MOUSE                                                                                                                          

• A convenient and contractible Mouse that can reduce 57% thickness after contracting.

• Designed the detailed mechanisms and manufactured the prototype.

​

Parallelogram Robotic Arm Project

• Designed a 3- degree of freedom Robotic Arm that can grip objects weighing 1.8 kg.

• The design features with parallelogram linkages that can reduce the moment of inertia and lower the center of mass.

• Higher structural stiffness, larger workspace, and higher payload ability compare to regular serial robotic arms.

​

​

Modular Vehicle Powertrain and Chassis Design

• Designed a small automobile chassis and transmission systems with CAD software.

• The driveline and differential systems are designed in a way that makers can easily prototype with 3D-printing and machining.

• Robotic arms, cameras, and other equipment can be integrated with this chassis and powertrain module design.

​

​

Hub Motor Module Mechanical Design

• Designed a hub motor module consists of compact planetary gear sets to magnified the output torque.

• This hub motor module concept can be used for wheel-hub motors in electric vehicles or joint actuators in robotic arms. 

• Designed the output flange with convenient studs and threaded holes for wheel mounting or serial robotic arm assembly.

​

​

Mobile Soccer Robot

• Designed a mobile robot that can play robot soccer games.

• Designed the gripper mechanism which features a much larger workspace by synthesizing the optimal coupler curve.

​

​

Cam Mechanisms Profile Generator

• Programmed a set of MATLAB codes that can generate profiles and curves (including position, velocity, and acceleration characteristics) of cam mechanisms.

• This generator can automatically fit the desired displacement points and the corresponding rotation angles specified by user inputs.

• Engineers can utilize this cam profile generator to design pick & place motion of automation systems, gaits of walking quadruped robots, or other related applications.

​

​

Leg Mechanisms Design using Function Generator Synthesis Method

• Developed a geometry generator that can help designers to create linkage mechanisms in GeoGebra.

• This geometry generator can synthesize linkage mechanisms that pass through three arbitrary points specified by the users.

• The generated mechanisms are mainly used for robot leg mechanisms or automation systems that follow specific paths.
