 | | What can I do with a robot?
|
|
A question for all of you fantastic robotics enthusiasts out there: I have to do a final year project next year, and I'm getting a head start on designing it. I've been told that I can do pretty much what I like with a robot, as long as it has a lot (...) (27 years ago, 25-Oct-99, to lugnet.robotics.handyboard)

Rob, I use these same encoders just as you do, and they work fine. However, the spacing of the encoders from thier targets is important for proper function. 1.5 to 2 mm works well for me. In addition, I have had to play with the encoder high (...) (27 years ago, 25-Oct-99, to lugnet.robotics.handyboard)

| | How do I connect 100 photocells to my handyboard?
|
|
Hi, For a project I'm working on, I need to track the output of one hundred (100) photocells. I don't need great accuracy on any of them, but maybe a ten-step resolution at the most. Is there a relatively standard or well-known method to gather (...) (27 years ago, 25-Oct-99, to lugnet.robotics.handyboard)

|
|
I've got a strange problem that probably has an easy solution, but I've been trying to hard to figure it out and am afraid that now I'm missing the obvious. I brushed the dust off my Handy Board to build a robot for my middles school robotics (...) (27 years ago, 24-Oct-99, to lugnet.robotics.handyboard)

|
|
Hi all! As I plan to build a Handy Bord, and as I am a bit far away from USA, I just would like to know if there is anyone living in France (and maybe in/near Paris?)... Electronic components aren't really cheap here, so if I could share tips about (...) (27 years ago, 23-Oct-99, to lugnet.robotics.handyboard)

Tried what you said Joshua, I went through all the analog ports and manually fed them with a TTL signal from a function generator at a relatively low frequency of 5Hz and wrote this little test code to test it. In this example, the sencdr3.icb has (...) (27 years ago, 23-Oct-99, to lugnet.robotics.handyboard)

| | Re: Analog port shaft encoder

Rob, Another suggestion for debuging your setup would be to write a program which; 1, anually counts the pulses from the encoder, and writes them to the lcd screen; or 2, Just writes the state of the encoder input to the screen (a 1 or 0). Then you (...) (27 years ago, 23-Oct-99, to lugnet.robotics.handyboard)

Hi, I am having great difficulty trying to get my shaft encoder to work using both sencdr3.icb or fencdr3.icb driver. I am using the QRB1114 optical sensor connected to analog port 3 with a current limiting resistor of 330 ohms for the emmiter and (...) (27 years ago, 22-Oct-99, to lugnet.robotics.handyboard)
