Fourth-year Mechanical Engineering major Jess Visaya and Fourth-year Mechanical Engineering major Dorette Pirie show off their soft robots. The robots are made to mimic worms, whose bodies bunch up before extending to propel themselves forward. The robots use pneumatic actuators to make linear movement outwards. Visaya and Pirie set up two of their worms with syringes attached to tubing which was then threaded through the end cap into the worms. Visitors to their station were encouraged to race the two worms by pumping the attached syringes. Third-year Biochemistry major Ira Evetts worked in Dr. Christopher Whidbey’s lab studying the vaginal microbiome, in an attempt to better understand the different microbes that build it up and how it affects health outcomes. Evetts’ research was specifically focused on lactobacillus iners, one of several bacteria naturally present in a healthy vaginal microbiome, and methylation systems. Fourth-year Mechanical Engineering major John Diesko Boehm and Fourth-Year Mechanical Engineering major Ian Agopsowicz hold up their “DAQMobile.” They built their project, a modified RC kit car, to help teach mechanical engineers about circuits and electrical design through real-world application. Fourth-year Mechanical Engineering major Ben Murphy holds up his mole crab and crawfish-inspired burrower. Murphy wanted to imitate the motion of a crab’s legs through robotics, with the primary goal to “turn the rotation of one motor into four alternating legs that would successfully displace soil.” Murphy was inspired by works that take inspiration from the natural world, and he found mole crabs particularly interesting. Although a mole crab is at an advantage with its burrowing being underwater, thus the sand being fluidized and easier to displace, Murphy’s machine is able to successfully burrow three centimeters into the ground. Second-year Mechanical Engineering major and Physics major Arabelle Miller shows off her rubber gripper, inspired by kirigami and origami. She took a piece of rubber and strategically cut slits into it to make it fold the way she needed, then glued googly eyes to the front. The gripper is able to hold up to 38 times its weight, or 226 grams. Third-year Mechanical Engineering major Joonseong Park talked about how his project took an unused and broken 3-D printer and transformed it into a testing platform for soft robotic grippers. The former-printer was reprogrammed and had its extruder part modified to be a mount for the grippers. Park shows off some of the other grippers that can be attached to the testing platform. Park classified grippers into two large categories. The first set of grippers is designed to deal with small delicate objects with great precision, and the second is made to lift heavy or large objects. Third-year Mechanical Engineering major Jiashuo Liu set out with a goal to deploy free open-source AI models to pre-existing robots to integrate object recognition and retrieval and command. The models are used to process the data received from the robots’ cameras in order to detect certain objects and their locations. Fourth-year Mechanical Engineering major Cole Purohit focused on agricultural automation of raspberry picking. His project utilizes kirigami to make grippers to close around a raspberry when the two ends are pulled. “Nobody wants to eat a squished raspberry,” Purohit said. Fourth-Year Biochemistry major Mariel Nolan’s project focused on bacteria and proteins within the bacteria whose functions are unknown. Nolan’s research is finding a way to isolate those proteins with the ultimate goal of determining their functions. Fourth-year Mechanical Engineering major Kai Boydon and Fourth-year Mechanical Engineering major Evan Nguyen show off their project, which uses custom extensors to help with the rehabilitation of stroke patients. They compared their project to a “party-popper” in the way it unfurls itself when placed under a patient’s fingers, helping the stroke patient rehabilitate finger movement. Boydon shows off the testing rig built for their project. It works as a mount for their extensor, as a way to test against resistance. Their program inflates the extensor through an air pump, which then makes the extensor push against the bed whilst an arduino calculates the force created and air pressure associated with the force.
