E128 - Advanced Engineering Graphics
Spring 2010 with Professor Lieu

Earned the Alexander and Ethel Levens Award for excellence in engineering graphics, computer aided design, 3D modeling and animation
  • Software - Pro/Engineer Wildfire & 3D Studio Max 
  • Modeling -  Reverse engineered Bumblebee the Transformer from an action figure toy. Collaborated with a team of four over three months to model and assemble the eighty components. Personally modeled twenty individual leg components from the hip to the toes. 
  • Assembly  - Components assembled with translational and rotational constraints on each joint.  Inverse kinematics tools were used to simulate the robotic motion of the transformer.
  • Animation  - Rendered a 10 minute animation with multiple scenes and transitions. Animated the assembly of the eighty components and transformation from robot to automobile. Included sound track, lighting, and special effects. Wrote an entertaining storyboard with Bumblebee dancing after the final credits.

ME102B - Mechatronics
Fall 2010 with Professor Kazerooni

  • Overview - Senior design project to prototype a device controlled by an Arduino micro-controller in one semester. Built a parallel robotic arm where the effector end remains parallel to the ground
  • Kinematics - Solved a system of equations using inverse kinematics to relate the angular position of the top parallelogram to the position of the effector. Prototyped and tested the dynamics equations in MATLAB. Compiled final C++ code using an Arduino micro-controller.
  • Software - Taking input from the user through a Wii controller, the micro-controller interpreted the signal to desired coordinate in 3D space and translated that location to a series of output angles on the robotic arm. The micro-controller sent corresponding PWM signals to the 3 servo actuators on the robot.
