For the sake of simplicity i will use the start here robot to ask my question, as the controller in the robot I am building here will be no more complicated (2 motors, one sensor) than that, and use the same processor (picaxe28x1)

The question is; Would I be able to use continuous rotation servo's instead of geared motors as the means of transport.

The differences and complications i've run into are -

Trying my hand at making a computer interface for a PICAXE28x2. Plans are for it to send serial data through the programming cable and for that data to be interpreted and acted upon by the picaxe. To test how this serial communications works, i've set up the following code on the picaxe.

interface:

    serrxd b0
    if b0 = %00000001 then
    sertxd ("Recieved")
    end if

    goto interface

I'm having a problem trying to control this display with an 08M.

by using the serial comms protocol from this manual for the display, all i achieve is scrambled flashing of zeros. After applying a smoothing cap to the power rail i have achieved relative stability, but its still just zero's that refresh their position every time the serout command is used.

I intend to build a remote 'weather station'

The station will:

• Be completley independant of any external power, ie, it will produce its own power via solar cell(s)
• Measure temperature only
• Transmit its finding over an RF link to an indoors reciever

Instead of using a rechargeable battery supply with charger circuit, i have decided to use a 35F, 2.7V super capacitor to smooth and store power.

More Recent UPDATE: the competed remote can be found here. Thanks to fritsl and rik for their respective helpfulness.

UPDATE: Attached (and blurrily pictured below) is my schematic that i think will work for this remote. Yes I drew it in paint, Yes it took too long:

*The "To Breadboard" leads are included so that the remote may also serve as a portable power supply.

What I intend to do is create a wireless link between my robot and my laptop, for remote serial programming, and remote control.

I posess a PICAXE 28X1 project board that i wish to connect with an XBee module.

From what I've seen in http://www.rev-ed.co.uk/docs/axe210.pdf an AXE210 is suggested. On page 9 however, we find that the XBee is only connected to the AXE by three pins: two inputs and one output.
