Abstract:
1. A three-axis robotic system comprising: a foundation base; at least a first post, mounted to the foundation base; a backbone-free first linear base mounted atop the at least a first post and parallel to the foundation base; a first carriage slidably attached to the first linear base; a first motor attached to a first end of the first linear base and having a first drive pulley; a first idler pulley attached to an opposed second end of the first linear base; a first belt that is looped around the first drive pulley and the first idler pulley, and attached to the first carriage so that the first motor can move and accurately position the first carriage; a backbone-free second linear base mounted to the first carriage only at a first end of the second linear base, parallel to the foundation base and orthogonal to the first linear base; a second carriage slidably attached to the second linear base; a second motor attached to the first end of the second linear base and having a second drive pulley; a second idler pulley attached to an opposed second end of the second linear base; a second belt that is looped around the second drive pulley and the second idler pulley, and attached to the second carriage so that the second motor can move and accurately position the second carriage; a third linear base mounted to the second carriage at a first end of the third linear base, orthogonal to both the first linear base and the second linear base and perpendicular to the foundation base, with an opposed second end of the third linear base further from the foundation base than the first end of the third linear base; a third carriage slidably attached to the third linear base; a third motor mounted at the second end of the third linear base; and a leadscrew mechanism coupling the third motor to the third carriage such that the third motor can move and accurately position the third carriage.
