Stingray AppMod

Hey all,

I was wondering if I can easily connect an AppMod module designed for the BOE to the control board on the stingray robot... You see, I'm looking to attach the CMUcam for the BOE-bot onto the Stingray, so how difficult is that?

Also, I'm looking to connect the gripper for the BOE-Bot to the Stingray. Is this possible?

Thanks!

    It should be fairly easy. The Stingray provides 5V and has 5V logic level shifters. Similarly, the gripper just needs a source of 5V for the servo motor and either a 5V or 3.3V servo control signal which the Prop can easily supply.

    OK, so can I plug the CMUcam directly into the Stingray breadboard? From there, attaching wires to connect it to the robotics board should be the best way to go, right? Any other hints/tips?

    I'd be careful about how you mount it. I have no idea how much the CMUcam will throw off the center of gravity of the Stingray, but be careful. You might want to figure out how you'd protect it against collisions. The fact that it should be easy to connect doesn't eliminate the need for common sense and good design.

    the stingray is significantly faster than the boebot. take that into consideration as well

    And you cannot plug the CMU Cam directly into the breadboard...the AppMod headers are dual row...but plugging it into the breadboard would short the rows of pins together.· You will need to find a way to mount it without the header and then use pluggable wires to connect the pins you need to the headers on the Stingray Control Board.· Take care.

    physically, does the stingray have a good mounting point for the gripper? Or will I need to make some HW modifications?

    The BOE-Bot gripper was designed for the BOE-Bot. I have not even thought of trying to determine if it would work for the Stingray.

    The Gripper kit is not as easy to attach to the Stingray as it is to the Boe-Bot.· The Stingray will take some thinking and and some modifications in order for it to work.· The CMU Cam will require some brackets and custom wiring.
