Meet Shuffleshock — our heaviest and most powerful antweight robot.
Shuffleshock is a shuffler, which means it doesn’t use wheels or other rolling drive systems. Instead, it moves on alternating legs. This gives it a 50% weight bonus, allowing us to put much more mass into its weapon.
Shuffleshock falls into the vertical spinner category, with a weapon best described as a “drisk” — something between a drum and a disk. The sharp weapon geometry helps it bite into opponents and launch them high into the air. Its strategy is simple: spin up, keep the front pointed at the opponent, and charge forward.
The chassis is printed from Super PLA+, while the top section and side guards are made from TPU. The result is a compact, tough, tank-like robot built around one very aggressive weapon.
Shuffleshock v1
Version 1 started with one clear idea: build a robot with the strongest weapon possible. At the time, that meant for us making the weapon as heavy as we could.
To make that possible, we needed the weight bonus — so Shuffleshock became a shuffler. It used a non-standard cam-driven walking mechanism with three long rubber-coated plates on each side. The idea was that the large contact area would provide strong traction. The legs also had small protrusions so the robot could drive upside down. In reality, the system didn’t work as well as expected. The movement wasn’t smooth, and the speed was low.
The whole robot was printed from ABS. The weapon was a 5 mm thick single-tooth carbon steel disk weighing around 90 g. It had so much energy that at 100% speed, the robot became completely impossible to control.
At the front, four spring-loaded wedgelets were added to improve low ground clearance against pushers. The springs helped keep them on the floor, even through vibrations and the stepping motion of the legs.
Shuffleshock v2
Version 2 received a completely redesigned leg mechanism. It was smaller, faster, lighter, and easier to manufacture. The smaller legs also allowed us to change the body geometry — making the robot shorter and wider. This version also marked the switch from ABS to Super PLA+.
The weapon changed as well. We moved away from
