mechatronics

Here is a semester project in the 2012 Mechatronic control systems engineering module at San Jose State University. This is a Proportional-Integral-Derivative controlled (PID), 6 degree of freedom (6-DOF) Stewart platform, which basically means it has six axes on the top plate. This prototype uses 6 radio controlled servo motors instead of the traditional use of hydraulic jacks or electronic actuators. (this video has sound)

Proportional-Integral-Derivative:

A PID controller continuously calculates an error value as the difference between a measured process variable and a desired setpoint. The controller attempts to minimize the error over time by adjustment of a control variable, such as the position of a set of servo motors or actuators,  to a new value, given by a weighted sum:


where Kp ,Ki , and Kd, all non-negative, denote the coefficients for the proportional, integral, and derivative terms, respectively (sometimes denoted P, I, and D).

  • P accounts for present values of the error , and is determined by the direction and magnitude the correction needs to be applied (e.g. if the error is large and positive, the control variable will be large and negative),
  • I accounts for past values of the error (e.g. if the output is not sufficient to reduce the size of the error, the control variable will accumulate over time, causing the controller to apply a stronger action through P), and
  • D accounts for possible future values of the error, based on its current rate of change. This part determines when and at what rate it needs to reduce the magnitude of its action, e.g as the ball fast approaches the desired set point at the centre of the plate.

“The story gained some morbid attention earlier today when a Financial Times employment reporter named Sarah O’Connor tweeted the story, not realizing the connection between her name and character who has a similar name (Sarah Connor) in the Terminator series. Her tweet was retweeted more than 3,500 times and she received an influx of messages making jokes about the news.”

Not your average robotic hand, this one developed by researchers at the Institute of Robotics and Mechatronics in Germany “was specifically built tough for jobs that might ding it up.”

I Have Finally decided what I want to do… mechatronics baby ♥_♥ Its PERFECT 

Only one uni does it in London .. So I’m not sure, Do I just apply to that uni and hope I get in but what if I dont get in :O 

or just chose another course :/ 

UGHHHH … Oh and I only have one week to write my personal statement which means I have to make my decision sooon 

My friend / colleague is preparing to program the robot. (That weirdly does not have its own name yet.)

The black box is the power source, it is used when the robot is not running on batteries. The charger is a separate device. Marek prepares to program the robot by connecting the chassis to the ground of the USB port on his laptop computer. Our guys learned to do this the hard way, as you’d guess something went very wrong previously…

It turns out that studying how to make robots grasp objects with their hands is helping researchers figure out how to make robots balance on their feet.

Christian Ott and his team at the German Aerospace Center's Institute of Robotics and Mechatronics have discovered a way to keep bipedal robots from falling over by using principles from robot grasping.

As shown in this video released at the 2011 IEEE-RAS International Conference on Humanoid Robots in Bled, Slovenia, the new approach allows the DLR Biped, a legged robot based on KUKA’s lightweight system, to keep its feet firmly planted on the floor, even when kicked by a mean researcher or slammed with a 5-kilogram medicine ball. You try to do that!
