Post 5: Hard Candy
[Insert Image of joints] With the design of the upper ramp somewhat finalized, we decided to modify it slightly to make the ramp more rigid. We replaced the previous 20-20 […]

Post 4: Small Solutions
[Insert Image and dimensions of the claw] We created a new, smaller claw that was still capable of holding the egg in place, but not too large that the eggs […]
Post 3: A for Effort
We created a mover mechanism and powered up a stepper motor for the first time, which taught our programming team (Wanyao and Wenshan) plenty about the process of preparing the […]
Post 2: Roll, roll, roll your boat:
Our first ramp uses a pair of guide rails to ensure that the egg rolls into the right position. We gave the base a width of [Insert Number] and the […]
Post 1: Heavy Metal
After surviving on 3D-printed components held in place with tiny screws, we were finally ready to move on to the big stuff. As our ramp would not have to bear […]
Post 7: Optimization
[Insert Images of topside damaged eggs] Our current claw design was able to crack the egg reliably on the claw, but we often ended up with the egg shattering […]
Post 6: Taking the Plunge
The plunger portion of the trident was meant to crack the egg by applying pressure on the top of the egg. Our development of the plunger was started off by […]
Post 5: Cutting Edge
[Insert image of Wenshan’s razor blades] We experimented with using Wenshan’s hair razor to cut the egg from below, but it, too, was not sharp enough to cut through […]
Post 4: Darwin’s Pincers
[Insert image of smooth surface claw] After some initial success with controlling the opening mechanisms of the claws, we constructed some full-scale claws to test out cracking the eggs. […]
Post 3: A Short Stop and A Sudden Stop
We experimented with another possible mechanism where the egg would be dropped from a height. [Insert Image of Ammar’s drop mechanism] This mechanism did not work out for […]
