VEX Robotics Setup

Today we created our team website with a modern design and all the information about Robot Lions!

First VEX Meeting

Today is the first VEX meeting. We practiced programming on the robot that I built over the summer. We also started building the herobot and our parents started making the field kit.

Robot Building Progress

We worked on the base of the robot. We also attached a frame. We split into two teams to do separate parts of the robot and the parents worked on the field kit.

Herobot Progress and Gear Ratio Lesson

We made a lot of progress on the herobot today. We also had a quick lesson on gear ratio, we also learned about input and output gears.

Robot Driving Practice

We started driving the robot and made stacks of 2 and 3. Sometimes the robot did not work but we fixed the problems. I think we can improve: driving the robot, carrying the pins and doing better turns.

Robot Improvements

Today we worked on improving the robot. First we tried fixing the turning speed, but it kept staying on the same speed. We fixed the wires so the wheels would not get stuck in the wires. We hope that next meeting will be more successful.

Robot Code Improvements

Today we worked on the code to make the robot less twitchy. We added a variable called deadband which makes it so that if it does not return to exact center it will not move at all. We also added 3 buttons: the first is E up which sets the drive_derate_speed to 1. The starting speed is 0.75. The second button is E down which sets the drive_derate_speed to 0.25. The third button is F up and F down drive_derate_speed back to 0.75. I think we made a lot of progress today.

Claw Height Fix and Big Goal Progress

Today we fixed an error that was preventing us from getting the big goal. Here is how we made the claw go higher. We made the part holding the claw taller. And we made a decision to keep some ropes. Today in my opinion was very successful.
