Variable Motor Speed Test OpMode

 


The goal of this meeting was to build a test OpMode for the Mechanical/Engineering team to use with the prototype shooter.  They wanted to be able to change the motor speed in increments of +/- 5 so that they could perform various tests with the launcher.

Nathan created a TeleOp OpMode and wrote the program while sharing his screen over the Discord video channel.  He used the opportunity to show Charlie how to map functions to the controller buttons and talked about some best practices like putting an empty "repeat while" loop after the button presses.  This eliminates the risk that the user holds the button down and the OpMode continuously changes the speed.

In addition to using the bumpers for +5 or -5 motor speed, Nathan assigned discrete values of 0, 25, 50, 75, and 100 to various controller buttons.  That way, the testers won't need to press the button over-and-over to get to some of the more extreme values.

Nathan also helped troubleshoot an issue related to variables in the REV Hardware Client.  Neither Charlie nor Nathan were able to create variables directly in the  REV Hardware Client on their desktop.  Nathan was able to temporarily work around the issue by creating the required variable directly on the phone and saving the OpMode to be edited in the Hardware Client.  He also identified that the software would delete the variable if it wasn't used in the code, so he had to add a line assigning a value to the variable before it could be saved properly.

Action Required: Nathan and Coach Jeff will do further investigation to determine why variables could not be created directly in the REV Hardware Client.

October 17 - Engineering and Programming Saturday Meeting

Image
 Today, the engineers have started working on assembling and implementing our intake system. Our team members have designed and 3D printed many parts to use in our intake system. We still have much to do before our intake system is fully operational and some of us will CAD some more 3D parts between meetings. The programmers tweaked the vision software to fit the camera used. It worked "spectacularly" as noted by a programmer. A flowchart was drawn up for the driver control period.

Enabling testing for the Intake and Flappy Servo together

 Previously, the programming team had supplied the engineering team with two test OpModes.  The first OpMode, called "VariableMotorTest" was a Teleop OpMode that allowed a driver to set various motor speeds.  This has been used by the team to help determine the right motor speeds to use for the intake motor and shooter motors. We also created another OpMode called ContinuousServoTest which spins the continuous servo.  This was used to help the engineers test the prototype "flappy servo" which is the mechanism used to transfer the disks from the intake to the shooter platform. At the Oct 19th meeting, the engineering team was able to mount the intake system onto the robot frame.  They were able to successfully test both the flappy servo and the intake motor, but not at the same time. At tonight's programmer meeting, we developed a new OpMode called Motor+ServoSpeedTest.  This OpMode combines the features of the other two OpModes by allowing a user to se...

Consistent Shooter Power

The PROBLEM:    During meet 1, we found that the shooter accuracy was very inconsistent. This made it hard to score rings in both Autonomous and Driver-Controlled portions of the meet. During the Driver-Controlled portion, the team could compensate somewhat if they saw they were shooting too high or too low, but we usually wasted a couple of rings determining how far off we were.  The DIAGNOSIS:    Shooter accuracy appears to have been affected by at least two different factors.   1) The mechanism for feeding rings into the shooter wheel did did not consistently deliver the rings the same way every time. Sometimes rings would be tipped at a slight angle when hitting the wheel or hit the wheel at a different speed.   2) The speed that the motor itself is spinning seemed highly dependent on the battery power. During one match, we used a battery that seemed overcharged and had a higher voltage than the previous ma...
