We went back to the machine shop to practice soldering and were able to do it despite having a few less tools compared to yesterday. For the first part of the day, we stayed there and kept soldering until we got the hang of it. We became more used to soldering and successfully did a few wires.
For the second part of the day, we returned to the Stem room to work on the robot. In the past, we had to use the serial monitor to see if the robot detected an object or not. This time, we found a 7-segment display to replace the serial monitor. We disconnected the Temperature Humidity sensor, wires, and resistor to create more room for the 7-segment display.
We went back to tronixstuff because it has a tutorial involving a 7-segment display, but the tutorial required 74HC595 shift registers, which we didn't have. Because of this, we searched for a tutorial that did not need those shift registers. Eventually, we found a tutorial that met our needs.

We reused some DetectTurnMove code in a new program called DetectTurnMoveDisplay with some adjustments. Successfully, the 7-segment display lit up as intended when it detected an object or not. Therefore, we don't need the serial monitor anymore for displaying detection. 

Programs written
  • DetectTurnMove
  • DetectTurnMoveDisplay
Goal
  • Practice soldering
  • Apply the 7-segment display to the robot

Summer 2 Internship 2018

07/05/2018 Zachary managed to finish redesigning the extending claw. While the overall mechanism is now smaller than the original, it still has some of the same issues; the claw itself is too bulky and two motors may be needed to raise or lower the arm. After building the prototype for the launcher Deepa started working on the launcher by attaching it to the base. the base that I built using mecannum wheel and four motors for each and to increase the speed of the motors I used the chains and sprockets. 07/09/2018 Zachary is working on a prototype for the arm's turntable and lifting mechanism. Depending on the length of the lifting mechanism, he should be able to mount the arm on or near a corner of the robot. This should help resolve any mobility and dimension issues presented by the original approach, as well as make loading the launching mechanism easier. The lifting mechanism's concept can be described as "a glorified lever." The extending claw will be ra...

VEX Robotics Competition: Transformer Prototype

VEX Robotics Competition : Transformer Prototype    I ntro The creative variability design of  robots dealing with   environments that  need  some unique mobility   presents challenges that can be tackled by the application of transformation principles for innovative design that opens  a larger  menu  of things that the robot   can do.    G oals O ur  research goals  for  participating in the VEX competition  are  not limited to  tackl ing  the main  objective  tasks, but to  invest  in higher score  opportunities  that call for   creative designs . An additional 6 bonus points are awarded for the team tha t secures the   center parking platform  a t   the  end of the  competition . The  center parking   platform  can be used by robots from either allianc e, it centers the two a llia...
