Telepresence Robot


 

Overview:

This telepresence robot is based on a robot I helped build on my FIRST team (Robodogs #435) during 2001. FIRST (For Inspiration and Recognition of Science and Technology) is an organization that promotes exposure to engineering through a teamwork based high school robotics competition.

This design serves as a modular test bed for examination of robotic control and sensor systems. The particular control system used is not documented on this sub-page, see Basic Stamp 2 Control System.

 

 

System Overview:

Frame 8020, 1010 Aluminum extrusion
Main Power 12V 17AH sealed lead-acid battery
Aux Power ICP Global solar panel
Max current draw 40A
Motor speed controllers Victor 883 (no longer manufactured, equivalent is Victor 884)
Drive Direct drive to 6" diameter wheelchair wheels by power wheels motor / gearbox.
Armor 1/8" polycarbonate
   
Main video camera Fixed Sony vidicon, lens:10.5-84mm F1.14, power zoom, auto focus, auto iris
Aux video camera Pan / tilt IR illuminated B/W ccd, FOV: 92deg, lens: 3.6mm at F2.0, sens: 0.1 lux
Video transmitter 2.4GHz omnidirectional
   
   

 

 

Robot Frame:

Robot's frame is constructed out of 8020 Aluminum extrusion. Extrusion is joined with 4 hole L brackets. Components are mounted on polycarbonate panels.
