Goliath Spring 2018 – Preliminary Resource Report

Figure 1 – Spreadsheet for expected expenditures for the Goliath Tank.
The cost report was based on the previous projects, with large uncertainty placed on 3D printing as it is undetermined how many iterations will be printed. Several items are free as they are provided by the class, others are taken from online. The shipping price is considered an uncertainty. Project allocation of $200 dollars was given by the mission objective to make a relatively cheap toy.
Figure 2 – Spreadsheet for the mass of the components.
Much of the mass report are assumptions, based on visual inspection of parts online. Many parts do not list the mass, such as sensors. It is decided to put 10% margins on all parts as they could fluctuate once the product solidified. Project allocation was based on a requirement that the Goliath shall withstand all impact with all robots; thus the chassis must be quite sturdy.
Figure 3 – Spreadsheet for the power consumption of the components.
The power report needs more information in measuring the power draw, this will be done once some sort of system is established for parts such as the 3Dot board and motors. Sensors’ measurements are from data sheets that manufacturer provide. Project allocation comes from the maximum instantaneous current the RCR123A can provide.
