[HTML][/HTML]Hello, I am Harrison from Team 2150D, a Freshman In High-School
I may or may not be the first to ever fully document my robot’s design process on the forums as a buildlog.
I will start off with what I have been doing for these first few weeks.
The first thing I did was analyze the game, and I came up with these points/ideas.
Starting with the Field Analysis:
[INDENT][LIST]
*]Lift Should Reach 60’ or Higher
*]Intake Should be Passive, or Pneumatics
*]Some Sort of Omni-Directional Drivetrain for Traversing the Full Field
[/LIST][/INDENT]
Next, I thought about how I wanted my drivetrain to formulate:
[INDENT][LIST]
*] 4 Motor
*] 4 Encoder
*] Meccanum
*] All Alum Chassis(Probably not best idea)
*] Pneumatic Tanks on Right
*] Control Systems on Left
[/LIST] [/INDENT]
Then I thought about the Lift In detail, and came up with a prototype:
[INDENT][LIST]
*] 7 Section Linear Elevator
*] +/- 40ft of Chain
*] All Aluminum Lift
*] 6 Tooth Sprockets
*] Mounted together with Bearings?
*] Lifts 72”(In Theory)
[/LIST][/INDENT]
[LIST]
*]Fig 1. My Prototype lift with 4/6 Motors
[/LIST]
Next, I thought of my intake, I still have not built it, hopefully I can do that this week:
[INDENT][LIST]
*] Pneumatic/Passive Claw
*] Holds Skyrise Cylinder ] Holds Cube @ 45 angle
*] Holds any other 1 Inch Dia. Objects
[/LIST][/INDENT]
Lastly, My Control System, Image of my mounting solution is attached:
[INDENT][LIST]
*] 30-40 Autonomous routes
*] 2 Highly Adaptive Autonomous Routes
*] Use Encoders/Optical/Line Sensors to Write
*] Cortex ALL ports filled up
*] Possible Telemetry display(Depending on Ruling, I have an RPi that can connect to the cortex)
*] LCD/LED Screen on back w/ Acrylic(In Pits ONLY)
*] Rerun auton routes
[/LIST][/INDENT]
That is all for this week, Hopefully I will have an update for you next friday
Are you planning on focusing on the skills challenge or competiton. I was just wondering since you are planning on using a claw instead of an intake roller.
I feel as if I may design 2 different intakes and test them out, one roller, and one claw, and this is REALLY early in the season, but my focus is skills, while still being able to perform well in competition.
I really like this idea of logging your progress. Everyone is looking for ideas early in the season and looking for working prototypes early on so they can see the outcome. More experienced people will cad their designs and such. I really do recommend an X drive if you want decent maneuverability and your lift looks fantastic already. Hopefully come end of the year you have a solid, well build design. Also with your lift, a lot of weight and friction can be cut back by using smaller sections of c-Channel (there’s a thread of elevator lifts for a better representation) and if you are not already, replacing each sprocket on the stages with just spacers. Also there are a few ways where u can make a passive intake hold up to 5 cubes and a skyrise section. Hint, its not a claw
We have had one on our street when they were doing stuff to our school and I had my little robot close to it and in the picture it looked very large like small fish trick.
