We were given the task of threading the wires through the loops and closing the loops, which was potentially a task for an astronaut in space. So what we decided to do was to make a handheld tool that could be used to complete this task in any orientation, and simply one-handed, regardless of which […]
Our task was to make a robotic tool compatible with an EVA space suit and that would function in zero gravity. The tool was supposed to a place green wire through twist ties and then secure the wire down by twisting the twist ties. We accomplished this by having 2 L shaped arms sticking out from […]
For this project we created a tool that would be able to route a wire through several black cables then secure the wire by twisting the cables. This was done using a combination of the EV3 brick, a medium motor, a large motor, two touch sensors, and an assortment of other lego pieces. The tool […]
Our tool was designed to route wires for extravehicular activity. It utilizes a gear with four sectors to twist the wire ties after each wire tie has been inserted in a different sector. The gear was 3D printed. The gear twists the ties with the help of the medium motor, which is activated by pressing […]
For our third project we built a tool that can be used to route a cable through some wires and then twist the wires above it to secure the cable. During design, we focused a lot on ergonomics, making sure that the structure is comfortable to hold, stable and as efficient as possible. We tested […]
For our project, we decided to create a handheld device that can screw/unscrew a nut and transfer it from one bolt to another. The main idea behind our project was to use motors and tires so that the spinning wheel with the grip of the rubber could screw/unscrew the nut. At first, we started […]
For our project, we had to route a wire through some twist ties, then secure the wire by twisting them. We accomplished this by putting a motor on one side of the brick and attaching a beam with holes in it to the motor. This way, the twist ties could go into the holes, and […]
Paul Gelhaus David Carratu Astronaut Tools: Astro Tool Documentation For this project we were assigned to remove a nut from a bolt and reinsert the nut onto a different bolt with a device we created with Lego Mindstorms. The device had to be something that astronauts could use, so there were […]
For our project, we needed to produce a machine that would unscrew a nut and screw it back into a different bolt in zero gravity, which is simulated by going upside down. Our machine completes this task by surrounding the nut, not allowing it to move up or down once it is […]
Our task was routing wires. Our tool uses L-beams to make a triangular shape for the two wires to go in. Then these two shapes are attached to the motor, so when the touch sensor is pressed, the motor turns the wires through the hole and twists them. Our initial thought was to have a […]
Task: Move nuts between bolts Design: Our design consist of one motor and a touch sensor, both of which are only attached to one side of the brick to allow space for the user to maneuver the tool with whatever hand they are using. The motor is connected to an axle that holds […]
