I have made a few posts about my senior design project, but this one is by far the best. We have completed the main deliverable for the project. Check out the video below to see what we did. The robot has amazing accuracy.

My senior design project has made some great progress. Besides all the software we have written, we have now officially mechanically integrated our robotic arm with our NI DaNI base. There are still some minor issues to work out, but the majority of the work is done. In the new year, we will be working on creating a demo to show off the robot’s flexibility. We will be posting a video with the new, integrated system working after classes resume in January. Since we have a fair bit of time (about 2 months) remaining, we plan to go hog wild on this project. If its worth doing, it worth over-doing, right?

We are entering the final stages of robot assembly and test. Last week, DaNI got a line following sensor from Parallax. This sensor is much like the Mindsensors Line Leader for LEGO MINDSTORMS. It has 8 IR light sensors that see the difference between the ground a line. We have a PID loop running on the FPGA on the NI Single-Board RIO to control out line following. Basically a PID loop helps us correct for not following the line correctly by using the error of our sensor measurements to determine which direction we need to move. To learn more about PID, wikipedia has a great article!
Also, Jason, one of my teammates, has finished the Inverse Kinematics for the arm. I have integrated the arm control into the motor drive train. The arm is scheduled to be mounted by Monday. After that we just need to physically validate our software drive model and we are done! Check out our video below!

My Senior Design Project at Rose-Hulman is integrating a kinematic robotic arm on the National Instruments Robotics Starter Kit (DaNI). DaNI is small mobile robotics platform based on NI SingleBoardRIO and Tetrix. We are working with the arm and DaNI as two separate systems right now and plan to integrate it in December. We spent the last few weeks working on constructing and controlling the arm. All software done in LabVIEW! Check out the video below to see our progress!
