WilbyWalker by Dennis Deckmann

WilbyWalker is a hexapod.  Legs and body are constructed 
mainly from acrylic sheet obtained from a dealer who sold scraps by
the pound, not even $5 worth.  Servos are standard ball 
bearing hobby grade servos and cost about $15 each. Each leg has two
degrees of freedom.  The brain is an OOPIC and the development 
kit was $50. WilbyWalker currently is operated under joystick
control, from my scrap heap. Each leg carries 4 AA NiCad cells 
for its own power, these were Walmart close-outs for cordless
phones and each 4-pack was $2.50.  A few screws, nylon 
self-locking nuts, sheetmetal screws, washers, cable ties, and
salvaged cable connectors added $15 or so to the bill.  
Additional materials are already purchased to add b&w video.  A tiny
camera was obtained for $30, an ATV transmitter for $100, 
and a video overlay generator for telemetry for another $100.
These are awaiting installation.  I also have a salvaged 
Polaroid SONAR module that I obtained from a scrap camera for $10...
