We went through multiple discussions and iterations to develop the hardware design of the system. This included testing individual components as we assemble the system together complemented with bringing in experience from prior projects and academic work.
As we faced challenges and new requirements we updated the design as appropriate.
We went through many iterations of the TOF sensor placement on the chassis, to best determine the design that would be able to localize the robot base in any orientation within the testbed.
After we tested the System Demo #1 configuration on our prototype test-bed we revised the positions of the TOFs for machining the holding slots on the robot chassis.
