Low Cost Mechatronics Trainer Video 1



hey this is Tim here I hope you're doing well we'd like to show you our low-cost trainer this is a project we've been working on for about six months now and it's myself on James Cafer James is a former student and he's got himself he's landed himself a big job in Baltimore now and he's been helping me with this for about you know six to eight months so why why did we why are we spending our time creating a low cost trainer this is something we've been taking about for a while now and we're filling in our mechatronics lab and were surrounded by some equipment that is fifty thousand ninety thousand dollars in price and we think that's crazy so we designed this ourselves it's like a little automated Factory any high school any Community College any university with a few dollars in their pocket and a laser cutter or a tree deep and a 3d printer can build this now just to be clear you don't need a laser cutter but it definitely helps so what we're going to do is we're going to James is going to explain how it works what you're going to guess if you're interested in doing this is we're going to give you links for all the drawings we're going to give you links for all the schematics we're going to well I don't know if I'm going to give you the PLC code but for nearly everything else you could possibly need I'd only give you the PLC code because I want you to write it yourself that's the whole point you know so what you need what is the James how much is how much do all these part how much is this cost to build us about 1800 hours per 1,500 bucks I don't I don't think a high school will need a high level of technical ability what what did we use we use a 3d printer the laser cutter definitely helped we ordered a lot of parts from automation direct open builds what else servo sissy as you 20 so there's a hell of a lot of them sensors there's a hell of a lot of complexity on the system and I'm sure you're bored of me and you want to see James explain it so James you want to give it a lush turn on reset start it this is a pneumatic system it throws out of our cups onto this linear actuator here and linear actuators driven by stepper motor system bear which is driven by a gear motor and a belt driven drive and lastly it stores it goes with another pneumatic system according to color and then you just hit reset and restart it and it goes back to the beginning so you have at least flexible coupling there you have your stepper motor with a stepper motor driver we have a light tower for indication so we're going to provide you with exploded assembly drawings builds and materials everything you could possibly need to build this thing how does the how does the system how is it able to tell the difference with the white and the black hands well right here we have our photoelectric sensors and we turn down the sensitivity for one of them in which the white cups sets it off and the black cup doesn't it because it doesn't it doesn't reflect gotcha so we're using let me just show you here our control system is a click PLC a click PLC is about $150 what else can we say about so what what happened but we ordered an awful lot of parts from automationDirect these cream parts wherever you see them are all made on our 3d printer so we have a lot of 3d printed parts everything is off-the-shelf 3d printed a lot of these black sheets here you see these black place there were laser course now if you're saying I don't have a laser cutter what am I going to do here you could make these with plywood very very easily I'm paint them and but a laser cutter definitely makes it easier you need about 1,500 1,600 bucks now we are using a pneumatic system here so in our lab here I don't know if you can see this oh come on here we go we have our own pneumatic system that runs around the lab now you don't need a fancy pneumatic system we're just running this off a $60 pump that I brought in from Home Depot it's made I was an airport or cable cheapo does the job you know so don't thing you can do is is you don't have to build all this once you could start off with this the PLC the click PLC the software is free you could buy yourself a light tower it's made by wolf automation and then you could have push buttons and you know you could just start off with this linear actuator or you could you could concentrate on one so we have three separate modules you could concentrate on building one module at a time we're just using plastic tubing here and we're just cutting it with a hacksaw and then filing this you're going to have to know an awful lot about wiring and that's it so we're going to hopefully give you everything that you could possibly want to build this and I'm really good luck with it so we're going to have more videos on this and how to build it we're going to provide teachers with curriculum and hopefully in a couple of months time or another large book of lab exercises to use this piece of equipment nice finally works every time hmm James why don't you run run us here and kind of explain what it does you have to turn it on now he's a mechanical engineer

    So the reason it's referred to as a "Trainer" is because ?

    Tim, your tutorials are the best, i almost watched every single one of them. Aren't you gonna make one about robotics? Maybe the very basics, or how to do little projects. Different joints or different movements and kinda mix it up with solidworks? What do you think.
