Comments and General Information:|
Designed and constructed to function as a watchdog for my yard, lying in wait, quietly off in a dark corner. Awaiting unsuspecting victim..uh err... intruder. Using ir motion detectors and sonar as sensors. PASIV will notify me at my pc of possible intrusion onto property, then Ask what action to take. Approach? Sit and Watch? Follow? (That should freak out an unwanted visitor). That's the goal.
PASIV currently weighs a little over 260 pounds. 32" long 26" wide 4' tall when standing. Track width 3.5" with 18" of contact area. This bot is driven by wheelchair motors. The drive motors will be powered by 36v, forward speed tested at 24V was 20' in 10 seconds. About the pace of a fast walk. The computers (3), sensors, and movement systems will be powered by a separate 24v power source feeding various DC/DC voltage regulators.
Estimated hours of construction is over 600 currently. (I work slow)
Each track is constructed of bicycle chain. 15 - 56" lengths per side. yea that's a lot of chain. Pinned together with music wire.(60 hours in each track.) Track skegs were handmade to keep the track under the boggy wheels. The drive system uses..... you guessed it. Bicycle sprockets. The torso Turrets are made from gear assemblies (6) from E-Bay. Wicked cool and powerful. The bot is built entirely of aluminum. 5/8 side plating and main hull construction. Plated in 1/4" alum.
Lathe, Milling and drilling on very old Machine shop equip. A hundard year old lathe, a Brown and Sharp horizontal mill dated 1893, and a drill press born not to long after that.
The head will house the computer systems.
The base will contain power and power controllers.
