***[https://www.youtube.com/watch?v=7K2H78NqQFA&index=11&list=PLElIOq0YqgutQ9XiZDJFwER6cDbSeWYK_ Loss vs. Silent Spring]
−
****Big Data's beater was not functional, so it only raced around Emmi trying to get hits.
+
****Sandi's wheels were not stock, and the different left and right wheels caused the robot to drive in arcs.
−
****Emmi's drum, after hitting Big Data several times, damaged its own motor controller, disabling the weapon.
+
****Silent Spring's weapon disk slipped between the baseplate and ring assembly, shearing the screw of a ring support.
−
****Emmi won by KO after Big Data lost mobility in its wheels, although Emmi was only mobile in one wheel.
+
****Sandi's ring was spinning at such high speed that it still hit Silent Spring's weapon, shattering it, throwing the robot across the arena, and affecting its steering.
−
***[http://youtu.be/DFWEbFbCFiI?list=PLa4DDbMiSUTWb6HBYu5YBsfiZMhEr4SHY Loss vs Devastating Moment]
+
****Sandi's ring was unable to spin up again due to the lack of support; eventually, the hubs slipped the drive axles on both sides of the robot, disabling it and resulting in a loss by KO.
−
****Emmi's drum, due to a missing tooth, greatly affected the balance of the driving, causing Emmi's front to bounce up and down.
+
***[https://www.youtube.com/watch?v=DfLB0D6Zh2s&list=PLElIOq0YqgutQ9XiZDJFwER6cDbSeWYK_&index=25 Loss vs. Ghoti]
−
****Devastating Moment, a Kit Bot, hit Emmi several times, removing Emmi's top plate and exposing the battery.
+
****Sandi (for a yet unknown reason) could not drive as well right side up as it could upside down, so its mobility was hampered.
−
****DM won by KO after Emmi's battery disconnected from its terminals.
+
****Ghoti went in for a hit, as Sandi would not easily move towards the other robot.
−
***[http://youtu.be/_gj1m9E5GIw?list=PLa4DDbMiSUTWb6HBYu5YBsfiZMhEr4SHY Loss vs Weta]
+
****The impact knocked both Sandi's wheels off axle due to the concussive force, disabling its movement. Ghoti was tossed and landed upside down, its bar bent by the impact.
−
****Emmi's movement was spastic yet again and was flipped by Weta, a Kit Bot, several times.
+
****Due to its initiation of contact, Ghoti won by KO.
−
****Emmi sustained much damage to its plates and had its rear "anti-flipping" bolt driven into the LiPo battery, resulting in a loss and a trip to the trashcan.
