Re: ÜberBots Hybrid Mode (Video)

Our first approach was to simply push a button according to which position the ball was in. That was inconsistent and had like a 30-40% chance of hitting the ball off. For the eliminations we just switched to the robocoach driving the robot forward backward right left and its much nicer

We are debating whether we should use this approach or if we should simply have the RoboCoach drive the robot. I've seen success with both.
Agreed, providing that
1. The stack approach is deemed illegal (which really is the heart of my question)
2. The IR sensor is positioned such that it can be sent a signal from the robocoach station while the robot is downfield.
3. The IR system works under the hostile IR conditions that can be at the event.

What kind of range/reliability did you have with that approach? I'm assuming that you had commands like "Drive forward for N loops" and repeatedly had to press the button.

Re: ÜberBots Hybrid Mode (Video)

I dont take any of this as an attack to my work, because i am completely aware that it is borderline legal/illegal. The reason we have it like this, though, is that we can justify that it does the same action every time, which is store a specific number to a variable, push that variable onto the stack, and then wait a half a second so that the robocoach doesn't inadvertently set invoke another press due to the nature of the IR signal.

We do realize the potential problems, and have backup code that does exactly the same thing, its just a bit riskier. the theory of this mode is the coach has 4 buttons, a1 a3, b1 b3. a and b are the different sides of the fields, and the numbers are the positions of the balls. the robot defaults to a2 b2, until the robocoach sends it a command that alters its default.

how do you drive it while still remaining within the rules?

Of course! Sharing is great.

I can't wait to see all the neat stuff other teams have to offer at the CT Regional.

Re: ÜberBots Hybrid Mode (Video)

we did a test today to show what happens when there are robots in our way.
its like they werent even there to begin with... it plows through them. the avoidance algorithms would work if we could position the sonar where it didnt see our own robot.
