This is actually painful to watch. I weep for all the bent C channels.
However this early in the season it is expected to see some huge (and costly) fails like this.
Nice chassis! I like your (conventional) X-drive and the sensors that you have built in.
In the subject of your lift I for some reason imagined it wouldn’t be descended from the 4 bar linkage: it looks like there wouldn’t be enough space in the chassis to mount pylons and store it within 18" cubed.
I have no evidence when I say I thank you have an elevator lift. That’s just how I pictured it in my head…
I believe batteries are a vital part of the robot…:rolleyes:
I see two ultrasonics, gyro, accelerometer, two (or three ?) line sensors, an IME cable going somewhere, perhaps to the motor labeled LUL (left upper lift ?). I’m looking forward to seeing some good software.
We have 2 ultrasonic sensors, 3 line followers, a gyro, an accelerometer, a potentiometer, an LCD, and 2 IME’s. We may add 2 more IME’s so we can use a PID to control motor speed and keep the robot going straighter in autonomous. During Toss Up we had the robot move about 4 feet and check the gyro and auto correct which sometimes made people wonder if we were controlling the robot with the remote. We ultimately started hanging the remote from the cat 5 cable during autonomous to remove any doubt. I think using PID’s will resolve any drift except that caused by loss of traction. I will have to wait to see what our programmer thinks when he get’s back from vacation, a PID loop is beyond my skill level.
So far, Wonka seems like it’ll be a powerful contender. I’m really curious to see how it actually performs. Part of it seems very simalair to the bot we(5212b) are taking to Hawaii, and ours is by no means a slow scorer. Best of luck!
I am still struggling to become proficient at building a Skyrise. The robot has been rock solid in autonomous which it should given the number of sensors it uses. We can score on the side goals very quickly since our intake and lift work very effectively, but I need a lot more practice to become a threat with building a skyrise. I suspect I will be building a more linear lift when we get home.
Why not just control all of your skyrise building in Driver Control by automation? Just press a button and watch it go, sit back and have something to drink, and score a ton of points. There’s no rules against programming an automated routine in driver control, right?
LOL, I have thought of programming one of the remote buttons to run an automated Skyrise build. I managed to score over 50 consistently with a 100% hands off autonomous in Toss Up and I think I can pull off a good programming skills this year. The problem is that I am using an 8 bar which makes the precision movements needed for building the skyrise difficult. I am getting a bit better, but with a few day’s left before I get on the plane for the summer games I doubt I can polish up a high scoring program for the skyrise sections. When September-October arrives I will be ready with a new iteration.
I am very pleased with the performance of my base and intake so far, I can pick up cubes and stash them quickly, but a good lift with more linear movement will be better for skyrise scoring and programming skills.
Yes, the claw uses elastics. The white spacers are loose enough to spin to allow the claw to expand and roll onto the skyrise section.
It is an 8 bar with 56" of total reach. It can score on all wall goals, build a 5 segment skyrise (6 is too time consuming) and score on a 6 high skyrise.
This robot measures 16.5"wide, 17.75" front to back by 17.75" tall prior to the start of autonomous at which point it is 16.5" X 22" X 23". The base is 16.5" X 16.5" and 20" when measured diagonally which allows a full 360 degree range of movement in between the autoloader and the skyrise base.
16.5" X 16.5" seems like a very small base for a robot that is nearly 5’ tall, but our anti-tip code using the accelerometer makes it to where it takes a sudden force of greater than normal driving to tip it.
