# Machine Week 2023 ``` everything's connected but nothing's working ! ``` # Your (Group) Task Each section will design and build a "machine" - this means anything that includes **mechanism, actuation, automation and application**, that just means: ### **Mechanism:** mechanical degrees-of-freedom (DOF) Stuff shuld move around. ### **Actuation:** computer-controllable motion of the above DOFs The motion should be computer controlled. ### **Automation / Application** software-coordinated computer-control of the above, and i.e. sequences therein The motion should result in some desired outcome... maybe make something, draw something, change something, assemble something, sort something, cast a spell, etc. > We can also think more broadly about "tools" - what does it mean to build a computer-controlled system that acts like a tool, interacting with the world but being mediated by some designer's intent... it's a [foamcore world](https://web.mit.edu/imoyer/www/portfolio/foamcore/index.html). --- # Examples / Ideas The machines you design and build **don't need to be complicated** - try to de-risk ideas early, and do stuff that "works right away" rather than complex projects that require hundreds of details to come together all at once in order to work. This can be fun; have fun. ### [Label Maker](https://www.youtube.com/watch?v=Y_rrbo6_42U&t=73s) ### [Wire Cutter](https://youtu.be/7E6iHRjvH_k?t=20) ### [Music Machines](https://youtu.be/dhKYxDzyXqI?t=5) ### [String / Floating Machines](https://youtu.be/dZLtPFJEQi0?t=104) ### [Architecture-Scale / Space Transforming](https://fab.cba.mit.edu/classes/865.21/people/gilsunshine/systems.html) ### [Claw Machine](https://youtu.be/zR3BLM_TAmg?t=117) ### [Robot Chainsaw Machine](https://youtu.be/ix68oRfI5Gw?t=1160) ### [Robot Basketball Hoop](https://youtu.be/myO8fxhDRW0?t=598) # Examples from this Kit ## MechE Components ### Framing Gussets ! IMG of each, link to cad. Maybe a set of them "deployed" in a chassis. ### Belt Axis ! IMG of it, link to cad and BOM, or a readme-each? ### Leadscrew Axis ! IMG of it, link to cad. ### A Rotary Axis Using [the design pattern explained here](https://ekswhyzee.com/2019/04/09/gt2-belt-rotary-cad.html). ! IMG of it, link to cad. ### The Blot --- ## MechE (examples) - clank - corexy (of dave) - beehive axes - ... add some more ## Examples - the blot (or some plotter: motion control, servo, stepper) - xylophone (motion control, low-fet, stepper) - drum stik (accel, low-fet) ## Stable Circuits - stepper - servo - low-fet - BNO085 ## Making new Things - how-to-add a new thing --- # The Kit | Part | QTY | Ordered ? | Arrived ? | Kitted ? | | --- | --- | --- | --- | --- | | **Hardware** | --- | --- | --- | --- | | FHCS M5x10 ? | x | no | no | no | | FHCS M5x15 ? | x | no | no | no | | FHCS M5x20 ? | x | no | no | no | | FHCS M5x30 ? | x | no | no | no | | SHCS M5x10 ? | x | no | no | no | | SHCS M5x14 ? | x | no | no | no | | SHCS M5x20 ? | x | no | no | no | | SHCS M5x30 ? | x | no | no | no | | Nylock M5 | x | no | no | no | | Washer M5 | x | no | no | no | | **Extrusion Situations** | --- | --- | --- | --- | | [V-Groove Extrusion 2020](https://www.amazon.com/BC-Labs-Slot-Aluminum-Extrusion/dp/B092HD1353/) | 2x 1000mm | yes | no | no | | HFS5-2060 | 3x 2000mm | no | no | no | | Extrusion Corner Brackets (?) | 20 | no | no | no | | [Extrusion Post-Install T-Nuts](https://www.amazon.com/Qjaiune-Aluminum-Extrusion-Printer-Profile/dp/B09H5B55ZG/) | x | yes | no | no | | **USB** | --- | --- | --- | --- | | [8-Port Powered USB Hub](https://www.amazon.com/Sokiwi-Aluminum-Expender-Splitter-Individual/dp/B099YS5DGX/?th=1) | 1 | yes | no | no | | USB A to C Cables | 7 | yes | no | no | | [USB C to C 240W Cables](https://www.amazon.com/LISEN-Charger-Certified-Charging-MacBook/dp/B0CL26CTYG/) | 1 | yes | no | no! | | [USB PD Charger](https://www.amazon.com/Charger-Charging-Station-Foldable-Portable/dp/B0C6K2PJJ8/) | 1 | yes | no | no | | [USB PD Decoys](https://www.amazon.com/Type-C-Trigger-Polling-Detector-Notebook/dp/B0BCW2LQP8) | 2 | yes | no | no | | **Transmission** | --- | --- | --- | --- | | [NEMA17 Motors](https://www.amazon.com/STEPPERONLINE-Stepper-Bipolar-4-Lead-Printer/dp/B00QEYADRQ/) | 5 | yes | no | no | | Kevlar 8800K43 | 50ft | no | no | no | | GT2 Pulleys | 4 | yes | no | no | | GT2 Belt Open | - | yes | no | no | | GT2 Belt Closed 280mm | 2 | no | (pull from stock ?) | no | | 6808 (? depds on rotary design) Bearings | 2 | no | no | no | | [625 Bearings](https://www.amazon.com/uxcell-625-2RS-Bearing-5x16x5mm-Bearings/dp/B07TML6YP4/?th=1) | 20 | yes | no | no | | [625F Bearings](https://www.amazon.com/%EF%BC%BB12-Pack%EF%BC%BD625-2RS-Ball-Bearings-Miniature/dp/B0BRQP2QG7/) | 12 | yes | no | no | | [Standard Roller Wheels](https://www.amazon.com/Official-Creality-3D-Printer-Plastic/dp/B09QPG7XGR/) | 20 | yes | no | no | | [Small Roller Wheels](https://www.amazon.com/3Dman-Plastic-Pulley-Passive-Bearing/dp/B07V4GHLL8/) | 20 | yes | no | no | | **Misc** | --- | --- | --- | --- | | [Limit Switches](https://www.amazon.com/JANDECCN-Switch-Straight-Action-V-153-1C25/dp/B0BDDCYTPP/) | 4 | yes | no | no | --- # Useful Design Notes [How to Make Something that Makes Almost Anything](https://fab.cba.mit.edu/classes/865.21/index.html) ## MechE [slocum: FUNdaMENTALS](http://pergatory.mit.edu/resources/fundamentals.html) [mechanical design principles](https://fab.cba.mit.edu/classes/865.21/topics/mechanical_design/principles/) [transmissions](https://fab.cba.mit.edu/classes/865.21/topics/mechanical_design/transmissions/) [kinematics](https://fab.cba.mit.edu/classes/865.21/topics/mechanical_design/kinematics/) [materials](https://fab.cba.mit.edu/classes/865.21/topics/mechanical_design/materials/) [common mechanical design patterns](https://fab.cba.mit.edu/classes/865.21/topics/mechanical_design/approaches/) ## EE (power electronics): [common switching architectures](https://fab.cba.mit.edu/classes/865.21/topics/power_electronics/architectures/) [commutating motors](https://fab.cba.mit.edu/classes/865.21/topics/power_electronics/commutation/) ## Metrology: [accuracy vs. precision](https://fab.cba.mit.edu/classes/865.21/topics/metrology/01_concepts.html)
