Leg Support #1
Design and Welding by Scott Sanderson
This is just one method to make a leg support system for the latex
rubber legs. Other methods can be just as effective.
An additional section of steel is welded to the steel knee plates
for strength and attachment of the steel rods. Square steel rod
stock is welded to the knee plates with flat steel stock added to
the sides for more strength. Bolts are welded into the hollow square
The waistplate is drilled to match the support bolts.
Holes are also drilled in the bottom of the fiberglass donut to
The rubber legs are slipped over the support system and holes drilled
to match the bolts. The front and back flanges (that match knee
plate hole) are cut off leaving just the side flanges to fall into
The waistplate and donut are secured with large handle nuts. Once
tightened the entire section becomes very strong and rigid and can
support the rest of the robot. The knee hinges will slip inside
the knee plates and the fiberglass knees will support the legs without
The inside of the leg support system has plenty of room to be used
as a costume and is very sturdy. The center portion of the fiberglass
donut was cut out for use as a costume.
