Heres a lower resolution vid (5MB as compared to 25MB)

Low Res 710 Video

that is very cool....we only use ours on the back of our robot and have an omni wheel bar that comes down and suppports the front...i really like the automation of the system...what are you using for the feedback... limit switches?

i like it and look forward to seeing this bot inaction

Thanks!

We use banner sensors, one in front of each wheel. The way it is set up is that when one of the sensors gets over teh step it pulls either the front or the back up. The driver controls if the banner sensors are activated or not with the trigger button on the joystick. I think you can see the banners in one of our posted pics. One thing we have to do at comp is reset the banners to the hdpe on the step. Works well for the most part and takes one thing out of the driver's hands (not that me and dan couldnt do it ;) )

Greg, as abeD said earlier, we're doing the same type of drivetrain. We are going to be using limit switches for feedback. We considered using other kinds of proximity sensors, but due to time and money constraints, we chose to go with the limit switches we had lying around the lab.

How about you guys?

look here you can see the banner in front of the back wheel.

we have a banner sensor on each weel that counts wheel speed.....as for climbing we either have nothing or we are using limit switches...i belive when the robot was shipped we had no automated way of getting up the stairs but i was promised it was being worked on, and since i have been on spring break i have no idea what progress has been made. i know that we are using a banner to determine height of our arms and with a linear pot controling the height of the arms....the nice thing about this is that we have clicks (for lack of a better word) at specific heights (stationary goal, mobile goal, hanging) so that the driver doesn;t have to guess and can just snap to the height.....i do think that automating the climbing with this type of drive is essential and we will have it by cleveland....anyway i am going to bed cause i am driving to trenton tomorrow morning for the NJ regional.....good job guys and good night
