FIRST Robotics
Unfortunately the competition was canceled due to COVID-19 which was particularly disappointing since last year we finished twelfth in regional and this year's robot looked like it would be highly competitive. This team has meant the world to me, now I just have to focus on applying what I have learned to the next chapter of my life with the design teams at S&T. Check out the timeline below to see how the robot has progressed.

We can hold 5 balls.
Have a 270 degree of motion turret.
The turret can adjust the angle for increased range.
Shooting footage with the finished robot. The build process outlined below.
This was the first shooter attempt but did not get the range we wanted.
This is our second shooter design. It had a range or roughly 30ft so we settled on it and moved on to other details of the robot.
We used two brushless neo motors with Sparkmax controllers. I made code for an Arduino mega to operate the motor controllers using pwm signal. This allowed us to turn it on and off with a simple switch. Code is on resources drive.
We then added legs so that we could play with the angle to see how accurate we could get the device.
Then we saw this YouTube video. This made the idea of a turret look too easy not to do so we started in the process of making a turret. We bought a lazy susan ring off amazon as our bearing to mount the turret on.
We then enter a long intermission where we tackle the details of the turret and how we could possibly climb as climbing was a first we were going to complete this year. About a month later we got this product and started building.
This is a close up on the shooter. The bearings on the hex shaft on the back behind where the ball will sit. These bearings when they spin smoothly keep the ball from being pinched between the tray and back bar. This allows for smooth loading when closing the tray without a complicated roller on the tray.
These are pictures of the almost final robot on the last day at school before COVID. Still missing the pickup and climbing mech.
This is our at attempt neat wiring because this usually turns into a rats nest. I used Velcro stuck to the medal then another piece stuck on top to hold the hires back. Then the rest are zip-tied in place.
The turret caused a lot of problems because there are a lot of wires to run the motors and sensors. The original plan was to use a cable carriage but this was complicated so we settled on the bundle of wires running up an arm above the turret then coming in the top near the center of the circle so that it will remain the same length as the turret rotates.
The robot is getting ever so close to final. Got some great footage of the robot actually working now that code is running. We now are only missing the climbing mechanism.

Never before have we been able to climb before. This year we have designed a climbing mechanism. Unfortunately this has not been built and I will update this post when it is made and tested.
