… many other functions. (Ok, poor reference to The Dark Tower.) I started working on this project a couple of months ago. This is a prototype for a larger project whose purpose was inspired by DARPA’s Grand Challenge. I wanted to experiment with remote control, telemetry, autonomous operation, navigation, and obstacle avoidance. So I started looking for parts, software, and what others had done that was similar to what I had in mind. Here’s a list of the major components I started with:
- Traxxas E-Maxx
- VIA EPIA M10000
- Logitech QuickCam 4000 Pro
- Delorme Earthmate USB GPS
- Acroname BrainStem GP 1.0
- Linksys USB Wireless Ethernet Adpater
There are a number of ancillary parts, including:
- 512MB of DDR 266 (PC2100) RAM
- 512MB Compact Flash Disk
- IDE CF Reader from ITuner CFDISK.5D
- VIA M10000 Kit from ITuner, which includes a 12V AC Adapter, and a PW-200-M power supply.
- EPIA USB Header from ITuner
- 10-Wire USB Header Cable
- A couple of 6″ and 12″ servo extender cables.
- An upgraded set of springs for the E-Maxx suspension from a local hobby shop.
- RS-232 to TTL level converter and extension cable
- A USB to RS-232 Adapter
- 1 or 2 spare hard disks (I’m using 1 with Windows XP Pro and another for Windows XP Embedded — more on this later).
- Pan and Tilt Camera Assembly
- Batteries and battery charges. I’m using 9V and 4-packs of AA NiMH batteries for the Acroname BrainStem logic and servo power. And 2 – 7.2V 3000mAh NiMH 6C packs to power the E-Maxx. I haven’t yet picked a battery to run the VIA motherboard and am still running it from an AC adapter.
I’m sure I’ve left some stuff out, but this is a good starting point. And I’ve been building a pretty good electronics bench over the years, and can’t stress enough the importance of tools and miscellaneous cables and components my wife insists are “junk”.
