Can the VRbot be built with a 8051 Microcontroller or does it have to be with the axon 2? Also, do you have a schematic for it?

I don't know what a VRbot is but an 8051 could be used to control a simple bot.
However, the 8051 is ancient (I was using these in the 1980's) but there is a ton of info on how to wire and program them. Also, there are now many variations of these processor so be sure to use the correct data sheet for the variant you are going to use.

If this plan to copying schematic and code to build the VRbot then you must use the same processor.

The bot I'm referring to is actually the one on this site. It uses a Axon 2 but I go to ITT and they only have 8051 so I have to figure out how to build that type of bot with an 8051, if that's possible. Or maybe I will have to do a completely different bot. I only have 10 more weeks to get it done and I need it to graduate

Sorry but I do not see any VRbot on this web site. I googled it but only found a voice recognition module call VRbot. How about a link.
Do you this:
http://www.societyofrobots.com/sensors_voice_recognition_robot.shtml

If so then this just uses a voice recognition module through a serial interface to an Axon. The Axon code is most likely written in C so if you have a C compiler for an 8051 AND you know the peripheral details on the Axon (Atmel processor) AND the you know the peripheral details of the 8051 you have, THEN you can change the code that deals with the hardware specific parts of the two processors and compile for the 8051. If you start working on this now you might get in done in a few weeks.

Yes, that is the one I'm talking about. The problem is, I can't find a schematic for the Axon 2.

I'm working on a project with a Roboteq controller right now.  I plan on developing.a Linux based system to control it and some others possibly including the rnet controller that pgdrives uses for rehab type wheelchairs.  If anybody is interested in helping with some c code let me know.

The VRBot board just uses a serial UART and power connection. If the 8051 has a UART and 5V power, you should be able to talk to the VRBot from the 8051. There may not be a step-by-step tutorial, but as long as you know the command set of the VRBot, and know how to read/write bytes from the UART, you'll be fine.
