i have good news and bad news. good news, i have the videos and i will post them at the bottom of my podt
bad news, again, my overly torquey motors not only ripped out of the sprocket, but it also ripped the sprocket in half, break the piece that goes onto the motor shaft its not too ttoo bad though, i amd using a stand off, some inginuity and plenty of hot glue and i think it will be fixed
now, for the videos (really sry about the quality, it looked much brighter on the camera ) media.putfile.com/Speed-Proto
this is the speed demo
Wow, thats a speedy lil fast bugger!! I wasn’t expecting it to be that fast and strong. If you wanna get more traction, keep the entire track down on the ground by putting a weight on the front.
Have you tried running the rover with the text books on top of the rover? I think that would be a bit harder than it would be to pull them.
Good work man, can’t wait for the lynxmotion tracks to come in.
I think it is correct. I timed how fast it took to move 7.7m (thats the length of my hallway) which was 5.5s. Than I did the math (average speed formula) and got that asnwer. Is it correct? I need to know becuase Its for a regional science fair. It seems correct because I am using this formula in science class this week.
You could have just done delta-d/delta-t = 7.7m/5.5s = 1.4m/s
There was some error because of the rounding converting to minutes. Most of the time, speed is referred to as m/s or distance/second. Lynxmotion has this wonderful little tool:
You can do a bunch of stuff based on knowing two of the following vars:
RPM
wheel diameter
speed
Of course that would be the theoretical speed or whatever you calculate for. It doesn’t include the fact that the motors might be too weak or too powerful.
I know that it is rarely used, but I for driving long distances, I needed the average speed per minute instead of per second. I drive ussually for like 2m straight with my bot, (especially when Im chasing people) so it works out for me
WOW! Wich motors do you have chunga?? and you to Italian guy? pretty fast over a meter per second! i’d get about a feet per second, wich is realy low compared to the crazy 1.4 meters! 8),maybe I will go with some gear head instead
Personally, I also think you should. They’re deffinately bang for the buck even if they aren’t as powerfull as planetary they compensate for good amount of torque and RMP’s. Deffinately a good choice, thats my 0.02.
anyway, i got the rover back up and running by switching one of the non-attached-to-the-motors-sprockets with the broken one, and it works beautifully
i was about to do some tests wen the batteries crapped the bed on me and wen i went to use my replacement batteries, i found that they were not charged , so right now im charging the 2 pairs of battery packs which took quit a qwhile, plugged them in at 5 yesterday, and they weren’t done at 10 wen i went to bed, they were finally done this morning 1 down…3 to go
as soon as i get some money ill will be buying the LM tracks, sprockets and the rest i need to make this thing have more traction, im going to have to make some new side types to compensate for the bigger sprockets but it should look good ill take some better videos after school today i will also satrt working on code to make it autonomous, ttyl when im otta school, later
well, considering the fact that i want to put on an arm on the bot, i have to resign the chassis and make it much bigger
i plan on making the arm with linear actuators and the bot is expanding to a massive 9" x 12" (the base of the arm alone will be 15" O_O) so it will hang off the back of the rover >_>
but, it will get the job done in lifting power, i plan of making it with 110 lb force actuators
anyway, lemme know wat u think, ill be getting more in detail once i get everything for sure and i have more time to talk about it
its not too ttoo bad though, i amd using a stand off, some inginuity and plenty of hot glue and i think it will be fixed
