Have you gotten your robot to go towards the vision tetra?

We can consistently get a vision tetra and raise our arm. About 80% of the time we can drive to the goal, and stack about 30% of the time. Some minor tweaking should bring these numbers up alot

For ours at this point it tracks and picks up a vision tetra consistently then looks for the goal.. Unfortunately at crunch time the mechanical had lots of work to do on the robot and I lost the time I needed to fine tune :/. Hopefully it'll be able to cap by the second competition O_O.

In regards to what the camera code will do with 2 tetras in sight, I believe I read that it will track the object with the largest bounding box (or closest tetra). However, by default, it will track the first thing it sees (such as another team's tetra). This is what we're doing:

1: Pan left and right while at a standstill.
2: Record the pan angle that located the largest amount of green.
3: Rotate accordingly and head forward.
NOTE: If you have to keep turning, your teammate may have that tetra...
5: When the bounding box is big enough stop, pick it up.
7: Relying on the starting position, and the initial turn from step 2, turn to the center goal (unless you dont want to cap the center).
8: Begin tracking yellow.
9: When the bounding box is big enough, stack.
10: Ungrab and backout.
11: Track a loading station?



Who needs drivers? Lets have a COMPLETELY autonomous robot!

AAah stopping... were still trying to get that part to work reliably.

Update: 195 Test-a-bot now succesfully finds a vision tetra within a 180 degree field of view, drives to it (quite fast, too), and stops 6 inches away, every time.

Whats next?

Ya we got our not "bot" but our practice kit bot to find the tetra and drive straight into it. Still have to do some work to mae it do something useful, though
