This website documents the progress of my real-life Halo Infinite Grappleshot project. The goal is to build a wearable device inspired by the grappling hook used in Halo Infinite.
The Grappleshot will use an ESP-WROOM-32 Mini, motors, and a pushbutton to simulate the functionality of the Grappleshot while remaining safe and portable.
This site will track hardware development, testing, upgrades, and future ideas for the project.
Initial CAD design for aesthetics and base footprint. Researching components and materials for the launching/retracting mechanisms and power distribution systems.
Started adding more things to the CAD model, including a basic placeholder motor model and set of model 18650s to check space requirements.
Started experimenting with the ESP32 microcontroller to control the system. Testing basic GPIO pins and button connection. Test failed, new boards need to be ordered.
Printed 2 stopblock models to test size and flexibility. The first had too smale of a score in the middle, causing it to over-flex and not spring back. 2nd model had a smaller score, but still had the same problem. A 3rd will be printed with an added 0.5mm of material in the middle to fix this issue.
Ordered 2 motors (1 spare)
Motors arrived, printed multiple prototypes of motor shaft fittings and prototype motor base fittings. The motor shaft fittings' threads are too tight, currently working on a solution.
Bought heat shrink wrapping for the battery pack and 16 AWG wire for connections. Footprint is large but accurate, motor and components fit, looks good so far. (In images, wires are taped to show where they go.)
The hardware will change as the project progresses and new solutions are tested.
Prototype photos and testing images will be posted here.
