Work continues. Due to poor weather we were unable to attend the week zero event in Suffield CT. We did, however, manage to get a lot of work done and some drive practice in at our work space, so it wasn't a total loss.
Assembly of one of the lifting bars. Each 'finger' is spring loaded on a rubber band and has two degrees of freedom allowing them to conform to the underside of the tote lips.

Drive practice with the arm! The tote stacker hasn't been installed yet. Between the weight balance being off, a very uneven floor and some frame quirks the mechanum drive has been less then perfect. Frustrating but all getting worked out.
The end of build is nigh!
