Our robot was not functioning as intended. It couldn't pivot left. The servos, when told to move at the same speed, didn't move at the same speed. We replaced a resistor, thinking that would solve the problem, but to no avail. We wrote a different progam called CalibrateServos to calibrate the servos. Eventually, we found the source of the problem in our initial program, DetectTurnMove, and corrected it. Now, the robot pivots, and the servos turn at a uniform speed.

We proceeded on with adding a seven segment display to the robot. With the display in place, the robot would display values for people to see ("0" if it detects an object, and "1" if it doesn't).

We added touch-sensitive whiskers for improving the range of detection but removed them soon after; we found out that the infrared sensor detects at a further distance than the whiskers.

Programs written
  • CalibrateServos
  • DetectTurnMove
Goals
  • Make the robot turn from an object when detected
  • 7-segment display to the robot in place of the serial monitor.
  • Improve the robot's navigation abilities

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...

Bergen Community College Robotics Spring Internship 2017 Initially, the old robotics team would like to welcome some of the new members into the team. OLD TEAM NEW TEAM (Members of the old team are only missing from the picture, not the team) Oh and we missed tyler, so here he is...... New Members: Deepa Banjara Alexandra Cortez Tyler Laursen-Carr The BCC STEM Robotics Team is developing a ball launching robot using Autodesk Inventor for design purposes and Robot C for programming purposes. The team has developed 4 major concerns about the design for the robot. First, the robot must gather the balls that are laying on the ground. Second, the robot must feed these balls to an elevator. Third, the elevator must elevate the ball to the launcher. Fourth, the launcher must be able to have varying angles in which it can launch the balls. To account for all of these factors, the designing team had to draw some sketches and ideas on the board for ...
