I have an idea about how to take coral and score, but my approach is only avaible for two stages. I’m new to CAD designing, so does anyone have any ideas about my CAD? How can I improve it, or is there anything wrong with it?
in there we have a telescopic cascade system. It can take coral from human player when its closed. But when you raise the system it falls down and it can score coral to reef. I didn’t add the pieces of angle. And in my cad i didn’t do the calculations. What do u think guys?
I don’t think it’s a bad idea, but if you intent on using a redline as I see in the CAD, you’re going to have to be careful, since they’re designed to run at full power to have sufficient cooling. If you intend it to run at a really low speed to hold the piece on, you might run into issues with the redline overheating.
use a bag motor if you have access to any, if not just make the ratio as big as you reasonably can, also probably want to use 1/4" plastic plates instead of 1/16" AL there, more for dimensional stability than anything. Remember to add “cooling slots” for the cooling ports on the front of the 775 so it can get proper airflow.
Actually, we are afraid to do it with plastic because we’ve been breaking our intake in regionals for the last 3 years. Thank you for your kind advice, it will truly helpful.
I replaced the steel plates with 1/4-inch ABS plates. This change will reduce the weight and make it more stable. I also added some churo to make it more durable.
I strongly suggest that don’t using Rs-775 Redline motor in your robot. It can cause big problems. You can’t get enough performance and you won’t be able to get motor datas accurately. I recommend that at least use a Neo v2 or Neo 550 motor in your system. Especially on top of your robot that Rs 775 will cause problems in wiring, use strong motors for durability.
a redline is not a bad choice, a bag would probably be better, but redlines are:
light
cheap
minimal wiring
packages small
there is no need for 5 gigawatts of power in this application
it will be run intermittently at low power (just make sure you have a safety cutoff for power over x% for t seconds in code, or just don’t give it much juice, it won’t need much)
So plexiglass is the common brand name for clear acrylic, which you definitely do not want to use on your robot basically anywhere as it is prone to shattering on impact.
Most clear plastic that teams use here is polycarbonate, sometimes shortened to polycarb, and sometimes called the brand names Lexan, or Makrolon. This usually won’t shatter under normal conditions and can take a beating. If it does shatter, it’s usually because loctite or another chemical has gotten on to it and messed it up.
I didn’t know that loctite damaged polycarbonate. Thank you for the information. In the Charged up season, we used plexiglass and it broke during the competition. Then we used 6mm polycarbonate in Crescendo, and it broke too(we used loctite on polycarbonate). This is why we are afraid of plastic, polycarbonate, and plexiglass plates.
Thank you for your kind advice, it will truly helpful.
