The Programmable Stiffness Joint varies rotational stiffness as desired by the user. It is the first step in modeling the mechanical impedance of the human ankle joint (both stiffness and damping) for the purpose of determining the respective breakdown of the two properties over the gait cycle.

IR Tracker

IR Tracker Main.jpg

The IR Tracker (aka "Spot") is a device that follows a moving infrared light. It continuously detects the position of an infrared emitter in two axes, and then tracks the emitter with a laser. See Spot Run.


Robot Snake

This remote control robotic snake uses servo motors with a traveling sine wave motion profile to mimic serpentine motion. The robotic snake is capable of moving forward, left, right and in reverse.


Programmable Stiffness Joint

The 'Steel Toe' programmable stiffness joint

The Programmable Stiffness Joint varies rotational stiffness as desired by the user. It is the first step in modeling the mechanical impedance of the human ankle joint (both stiffness and damping) for the purpose of determining the respective breakdown of the two properties over the gait cycle.


Magnetic based sample purification



Continuously Variable Transmission

CVT setup1.jpg

A continuously variable tramsission is intended to provide a transition from low to high gear ratios while keeping the engine input running at the max efficient speed. It is achieved by a system of variable radius pulleys and a v-belt.


Granular Flow Rotating Sphere

This device will be used to study the granular flow of particles within a rotating sphere. The sphere is filled with grains of varying size and then rotated about two different axes according to a series of position and angular velocity inputs.


Vibratory Clock

Vibratory Clock

The Vibratory Clock allows a small object to act as an hour "hand" on a horizontal circular platform that is actuated from underneath by three speakers. The object slides around the circular platform, impelled by friction forces due to the vibration. Check it out!


WiiMouse

HPIM1027.jpg

The WiiMouse is a handheld remote that can be used to move a cursor on a windows-based PC, via accelerometer input captured through device movement.


Intelligent Oscillation Controller

ME333 learning oscillator.jpg

This device "learns" a forcing function that is applied to a spring and mass system to match an arbitrary, periodic acceleration profile.


Baseball

Baseball Playfield.jpg

An interactive baseball game inspired by pinball, featuring pitching, batting, light up bases and a scoreboard to keep track of the game.
