> Problem is coming up with a strong enough steerable joint.
All the replies were apparently trying to help you to create a steerable
wheel with no motors in the assembly.
Did you consider rotating the entire motor/wheel assembly?
The advantage is that you don't need a drive to go through the rotating
components, as a flexible wire can deal with the movement.
The disadvantage is that it's difficult to make a rotating device which
can deal with the vertical forces involved in the "shrimp" design.
Maybe you can keep the entire front as a rigid assembly and put the
mounting points on a turntable on the top of the shrimp? It won't give
as tight a turn radius as rotating the drive wheel.
I don't suppose using Legos in the lost-wax process to make metal Lego
pieces, then welding them together, would be a fair way to solve the
strength problems.

| IN my design the motor and wheel assembly are one unit. The problem has been keeping the rotation point stong enough. Hopefully I can play around with some things this weekend. I will probably order the large turntables from pitsco. They should (...) (23 years ago, 23-May-01, to lugnet.robotics)

| I am building a shrimp-style rover along the lines of what Mario Ferrari built. I uses 6 powered wheels. A pair on each side in lateral boggies, One in the front on an articulated arm, a rear fixed to the chassis. Problem is coming up with a strong (...) (23 years ago, 21-May-01, to lugnet.robotics)
