The chassis is built with Aluminium parts from Tetrix FTC Kit. The wheels and DC motors are also from the Tetrix FTC Kit. 12 inch long sections of PVC pipe from Home-Depot were used to make the neck.
Starting with the initial 3D conceptual design, robot construction went through several assembly dis-assembly iterations, to fix minor problems encountered during construction. Final assembly steps of the main chassis are shown in the following pictures.
