Smaller Cheaper Robots

ROFL!! I'll use Solder over anything out there now. theres always a mechanical way to make things. Like the "night rider" LED thing i made for my team's robot. It was pretty much a servo which turned a metal arm which came into contact with metal pins which completed a circuit, and then turned on a certain LED. No relays or circuit boards necessary.

Smaller robots can be really fun. Here's a 1lb combat bot I'm making for the RoboNexus expo in October.



It uses 60:1 copal gearmotors ran at 14.8v off of two LiPoly packs in series, and a micro reciever from The Robot Marketplace

The speed control is an Ant-100 from Barello.net

The chassis is a milled block of UHMW

The tires are from a local Slotcar Track

Beyond that, all you need is a transmitter(75mhz, normally) and it's ready to go.

Note: this was milled on a mill from harborfrieght, and all the dimensions were figured out on the spot, so it is a bit sloppy, but perfectly fine for it's purpose

Hmmm, i wish there was a robotics convention in NY. Robonexus is just too far away to go to.

Bit of a follow up on my last post, here's the thing in action, but with one dead motor.
