Micro Motor Robot Chassis and Brackets

thingiverse

I couldn't help but notice that Actobotics had really nice motors that were small with encoders, but there were no open-source chassis available to download for cutting. I saw Pololu had a chassis, but I was going to find a more open-source solution that only used two motors and no more. I want it to be fast but yet maneuverable. Check the link below for the motor links. https://www.servocity.com/html/micro_gearmotors_with_encoders.html The chassis is meant to have two casters, two motor mounts, one chassis, and six brackets per robot for printed parts. The rest of the parts I am unsure about since it is work in progress. The robot is meant to use these wheels as well for the robot. https://www.pololu.com/product/1090 I also used these Thingiverse parts. Good luck!!! Thanks!!! I used this ping sensor bracket. http://www.thingiverse.com/thing:9107 I used this caster. http://www.thingiverse.com/thing:1408935 Last but not least, this motor bracket. http://www.thingiverse.com/thing:1364768 Print Settings Printer Brand: 3D Systems Printer: CubePro Rafts: No Supports: No Resolution: 0.25 Infill: 30% How I Designed This LibreCAD and nothing else other than using Thingiverse parts. I used this ping sensor. http://www.thingiverse.com/thing:9107 I used this caster. http://www.thingiverse.com/thing:1408935 Last but not least, this motor bracket. http://www.thingiverse.com/thing:1364768 I used LibreCAD for everything else. Micro Motor Robot Chassis Facts Micro Motor Robot Chassis and Brackets Q1: What could I learn from this? A1: You will learn many things from this robot; it is almost limitless. I am hoping to learn a little bit more about Arduino since I will be mounting an Arduino Uno to the robot along with motor drivers. You can also learn a lot from controlling motors and depending on what you use it for, you can learn obstacle avoidance, self-navigation, and more with robotics. Q2: How old is this robot's audience? A2: Honestly, I think the ages for the audience that should use the robot are 15.5 years of age and up. The reason 15.5 years of age is because I learned Arduino and robotics or at least the fundamentals of it when I was 15.5 years old, and that was pretty young for someone with so much talent for his age. Q3: How would I assemble this? A3: To assemble the robot, you are going to need M3 bolts of various sizes. This chassis only uses M3 bolt and M3 screws and nothing else other than M3 nuts. My apologies for those of you that need more specific details like what length of M3 bolts and screws. I honestly just used a bunch of parts in my basement that worked. Q4: How long should this take to build? A4: Depending on your skill level, it should take about half an hour to about two hours depending on what you are doing with it. If you are just assembling it, it should take half an hour. Q5: What skills will I need to make this? A5: You are going to need some programming knowledge, electrical engineering knowledge, and obviously 3D printing and laser cutting knowledge. Q6: Where can I get those skills? A6: Just to let you know, this site has some of the programming skills and wiring diagrams you need. https://www.arduino.cc/ Electrical experiences not a lot are needed, but this website I find helpful most of the time. http://www.allaboutcircuits.com/ If you are in need of 3D printing skills, I recommend this site. http://www.reprap.org/ I do not know any more than this. Very sorry if you need info for laser cutting, but I had a friend laser cut this for me. Q7: What subjects does this project incorporate? A7: What I find interesting about robotics is that robots can include any subject imaginable; it just requires some imagination and creativity. Robots include every subject; just Google search robots and your subject, and you could be surprised. Q8: Will more be posted? A8: No, this is a functional robot. Figure 1
