Summary

Second iteration of Meshbot. Now with more sensors!

Front and back edge detection sensors, one front ultrasonic ping sensor, front long distance IR sensor, and four IR proximity sensors for wall detection.

This bot is designed to work with the following parts:

  • Arduino Mega
  • Adafruit motor controller (or similar), a voltage controller, and a bunch of sensors
  • Pololu motors, quadrature encoder, 30T track set and sprockets
  • Radio shack 8AA battery holder
  • Radio shack 8ohm speaker
  • Radio shack lighted on/off switch
  • Radio shack red interrupt switch (for resets)

If anybody is interested I can provide more part details and general information.

This bot is called "Meshbot" because I use the mesh features of the Xbee antenna product family to allow robot-to-robot and robot-to-operator communications.

Instructions

Most parts are designed to be printed without supports or raft. The battery lid tabs are fairly small so you might want to use a raft there if build plate adhesion is a problem for you.

The pictures should show the assembly process, but I'm happy to add more details.

I'm working on an Arduino shield that is specific to this project, I'll release it here as soon as I can, along with the software.

this is great! i want to build it when i get the money and chance

Hi Jamie, nice bot design.
Can you provide more details about the hardware you used for the bot?

Thanks.

Hey VGer, congratulations on leaving the solar system!
No problem on the details, I'll put them in the instructions area.

"leaving the solar system!" . . . LOL
Its is dificult to get an internet connection this far.
