Hi all, I'm a lurker/newbie. I'm wanting to build a controlled platform that can move and rotate (sort of like a turtle using LOGO). I'd like this platform to carry my E-10 camera (weighs 37 oz./1048 grams). Can anything using the RCX/mindstorms (...) (22 years ago, 12-Nov-03, to lugnet.robotics)

(...) Could you tell what the angular resolution of the slotted wheel was? Thanks, Mark (22 years ago, 12-Nov-03, to lugnet.robotics)

(...) Well, I think this is going to work. Do you have any pictures of the logic/gearing used downline from the transmission? I am concerned with how the worm gear makes the transition from front to back and the resulting interaction with the drive (...) (22 years ago, 12-Nov-03, to lugnet.technic, lugnet.robotics)

(...) One thing you will find, is that you can't drive the motor backwards. Well, it won't go one direction. The direction depends on the wiring. Actually, that's just if you hook it to a motor port, AND a sensor port. I don't know how bad it is, (...) (22 years ago, 12-Nov-03, to lugnet.robotics.rcx)

A few hours after I was working with my brand new RIS kit, I knew the programming environment was too limited for my needs. Thanks God there was NQC out there, very young but already very solid, offering an entire new world of possibilities. Without (...) (22 years ago, 12-Nov-03, to lugnet.robotics.rcx.nqc)

To add some further information, I popped the unit open last night and observed that, as I had hoped, mechanically the unit should be capable of operating correctly. Each motor channel has a mouse style slotted wheel and sensor, so the firmware (...) (22 years ago, 12-Nov-03, to lugnet.robotics)

| | Motors on Sensor ports
|

I'm just curious if there's any harm in connecting motors to active sensor ports... I know you don't get very much voltage/speed/torque, but you do get interesting readings that can be used to detect when the motor stalls. This is potentially a very (...)

(...) That's one of the links I was trying to find the other day! Thanks. I'm not sure if it will do what I want, but I'll have to stare at it a while to find out. Keep the ideas coming, if there are more. -Duane (22 years ago, 12-Nov-03, to lugnet.technic, lugnet.robotics)

(...) You also might check out a construct called a Directional Transmission. This is a simple setup using a sliding worm gear that does pretty much what you are describing. Michael Powell has a web page describing his design that I used (...) (22 years ago, 12-Nov-03, to lugnet.technic, lugnet.robotics)

(...) One way to do that is to have a rubber-band/spring/shock holding "Output B" in it's starting position. Then, you can use a differential to move both A and B. Going forward, A will be easier to drive, so it will push A to it's limit, then B (...) (22 years ago, 12-Nov-03, to lugnet.technic, lugnet.robotics)
