Pretty cool robot. I’m assuming it drives over objects, but is it stable? Considering how high the battery is, it must have been a fair challenge to stop it from tipping over. Also, do you find the intake to be more effective than other robots that you are competing with?
i programmed the drivetrain with a speed ramp, basically when the arm is raised it starts at about half speed and increments up to my joystick value. There’s a lot of stuff going on in the code, and it’s messy but i’ll attach it.
In the semifinals at QCC, my robot disconnected from the field somehow, dead battery maybe? I’m not exactly sure… My wiring is a mess today, maybe tomorrow ill post a pic I can hold five objects, if stacked as shown here, and yes they will exhaust like that.
That is a c-channel by the way, there are only two bars connecting the robot together, at the top and that bottom c-channel, i needed the space for my manipulator. It actually is very sturdy and is much more robust than it’s last competition, where it made it to finals match three with two 817 teams (D and B, i think?) This robot was built by yours truly a week before that QCC event, and i have been improving ever since. As some of you may know, one of my teammates has quit recently, so about 70% of my team’s workload is on me, seeing as it is now a two person team. I drive and program, and my teammate and i work together when we can. Gateway WC Code.c (5.91 KB)
Nice robot! I agree with Telemascope that while your drive train seems to be designed to drive over objects, it has that one c-channel across the middle of the drive train that prevents your robot from using that capability. Without designing specifically to drive over objects, I’m wondering about the high CoG with the batteries/electronics as well as the minimalistic and (arguably) less structural chassis.
Edit: Just saw your recent post, why not go with the very common ramp intake instead? Or a hybrid flat -> ramp intake that will give you space for your flip-out manipulator? Not sure, just my first thoughts.
I have considered that, but I’m pretty comfortable with how this one works. Now i could always make a polycarbonate ramp so that objects can ride right over that c-channel. It is simply there for structural rigidity, which is very important to me. I will post a video when i can, which should answer many questions about it. The robot is about 75% aluminum, and the cog is not that much of a concern, which i will demonstrate with a video, due to programming of the drivetrain.
yes, it was, mainly the manipulator at first, we had taken that and put it on our old “swing lift” robot, but then i decided that a six bar would be much more efficient, allowing only two motors on the arm and naturally being much faster. It exhausts fast and probably about the same speed as the other types out there. I’m working on improving how well it holds objects though, the static sprocket and tabs need either more tabs (6 opposed to 3) or they need to be closer together
