Remote Control and Data Transmission using PIcaxe 40x2

Question for all the Picaxe users out there on LMR: I'm designing robot that will have autonomous object avoidance capability and wireless remote control, the mode be chosen preferably remotely as well. I also want to recieve data from the robot (sensor values etc) to a PC. Can anyone shortcut me to any existing projects that have done this with Picaxe?

Thanks

I haven’t with a PicAxe… I

I haven’t with a PicAxe… I have with Arduino and PC…  
What radio/wireless modules do you have if any?
I’d like to help if I can.

None yet

I haven’t bought any of the wireless modules yet - I’m still researching what will be the most capability for the $ in the fewest components. I’m growing concerned that Picaxe could be too limited to achieve this thought. Should have started in Arduino maybe.

Would not an xbee be sufficient to send and receive data?

Could you not use a pair xbee modules to send and receive data. If the module on your robot receives a valid move command then the robot should do as instructed by the input otherwise use the sensors that are giving input. Inside the main loop you could then send data as it is available. It really boils down to how much data and how far away you want to be able to have control.

*I only mention xbee modules as I have read that they are the easiest to set up, almost like a wireless serial connection.

Yep

I am currently doing the same kind of thing !

Robot’s main chip : 40X2
Remote chip : 40X2 (maybe I will replace it by a 28X2)

I use Xbee modules (one for the robot and one for the remote). The robot has several sensors ( 3 SRF05, 2 IR, tempetrature sensor, lasers etc.), a slave 28X2, servos (threw SD20 chip) etc. The main program checks sensors etc., when serial data is detected from the Xbee module (and so, from the remote’s Xbee module), an interrupt is activated.

This settup works pretty well !

Sounds close!

Very promising! Have you posted your project so I can read more about it?

Not yet !

Not Yet ! I have spent a lot of time prototyping the electronic. I wanted to be sure evereything would work as expected before making a clean PCB.

In the mean time, I can try to answer any question you have, our projects look close and I have met problems you might run into :wink: Feel free to ask :slight_smile:
