Seriously I wanna be like you when I grow up . I keep looking around for tracks like your but they are crazy expensive . Do you have a hook up state side ?

@@motorsandvoltsandrobots7162 That's awesome! Keep at it, watching more UKposts vids, making and breaking stuff while learning along the way and you'll be amazed at how far you've come. Stateside, it's a real pain in the ass to find tracks for robots! That's why I went directly from China from a company named PUYI INDUSTRIAL. At the time, I dealt business with a lady by the name of Alice Zhang. She helped me find the size I wanted. They even machined the drive wheels you see in the video. Unfortunately, rubber robot tracks are not really cheap, but these were affordable compared to other online websites. I bought these about 3-4 years ago and I paid roughly $450 with shipping. They offer their tracks for direct purchase on other websites such as made-in-china.com. If you Google their name, you'll find them. Hope this helps and best of luck!

@@Brute4rce1111 Do you mind sharing the belt specs for the one in the video. This is exactly what I'm looking for

Hey hurry up hahahha

Can you do some narration?

Thank you for you kind words! I am currently working on part 2 of this build, so Ill post it as soon as I can 👍

I am currently working on it, so you will see pt 2 soon! Because of my work/life, I had to put it off but I am now back on it 👍

Sure! Thanks for watching! Its been slow to make part 2 of this, but I am working on it now :)

Haha yea it is pretty stupid of me to grab them like that. I ended up learning the hard way and got cut on my thumb a few weeks later 🤦‍♂️. Thanks! The I beam definitely makes for a very robust frame for me to bolt everything to 👍 It is also great because there is no welding involved, no weak points, and very little machining is needed to get to a rolling chassis!

Thank you for kind words bro! I have been a little busy with work recently, but i will post more updates on this robot build as soon as I can :)

Thanks for the feedback! I'll keep that in mind when editing 👍😀

Yes it machines rather nice for it's size 👍

I appreciate your kind words! It really is satisfying to be able to sculpt a beautiful part out of block of metal, especially if you're getting paid for it 🤙

Thanks! I bought them from a company in Shanghai called PUYI INDUSTRIAL if you're wondering. Google search their name and you'll find them 👍

Thanks! That's awesome! 👍

Thank you for your kind words Cornel 🙏

Thank you!

Thanks!😊

Thanks! I will be posting more updates on this machine

I have been thinking about building a similar RC Lawnmower for several years, but the tracks are a problem. Where did you get the tracks and wheel set? Links would be helpful!!

@@donaldmcswain I bought them a few years ago from a company on AliExpress called PUYI INDUSTRIAL. If you google them, you'll find them on other e commerce sites like made-in-china.com. They are extremely helpful and willing to sell to anyone :)

Thanks! The wheels don't really need bearings because UHMWPE is a natural bearing material. It is self lubricating and has a very low coefficient of friction.

@@Brute4rce1111 makes sense. Thanks!

Thanks! I thought about putting a pick and place type of robotic arm on it, but decided to make it with a front loader/forklift arm mechanism. I wanted it to pickup and carry heavy weighted things like cement bags.

They would if you didn't change out the oil for grease. With the oil, it would starve the area dry being upsidedown. That was my only concern when mounting them like that. Because of this , I drained the oil and packed in grease instead.

Thank you 👍

Sounds like an interesting build! There are a lot of different factors that play a role in selecting drive motors, especially if your robot needs to climb at a 45 degree slope. That being said, I found it easier to get the biggest motors you can safely run without overwhelming whatever speed controllers you intend on using. For a robot your size, you could probably get away with automotive power window motors since they draw only a couple of amps, are inexpensive and they are already equipped with a worm gearbox. (The small Denso power window motors are great) The thing to really keep in mind is what overall speed you want out of the robot, the radius of drive wheel and theoretical max stall torque of the robots wheels. A 20 kg robot with a drive wheel radius of 100 mm going up a 45 degree slope would probably need at least 18 NM of total torque, so about 9 NM per motor as a quick guess. If the drive wheel is smaller, than it would obviously require a lot less torque to push it along. Hope this helps!

@@Brute4rce1111 Thank you for your reply. I'll most definitely have a look into the power window motors! They are 12V and might be a suitable size. There are the 250W 24V wheelchair motors, but the voltage needs change from 12-24V then + motor driver modifications. Ordered drive wheels are 150mm, so a motor @ 10rpm (IDK the speed) will make it run about 5metres a minute. Thanks! I'll order some powerwindow motors at first and see if they can do the job.

Thanks! From my early tests, it had a ton of torque with great traction! Unfortunately though, I had to put this project off for a while due to life reasons. With that being said, I am still committed to finishing the rest of the build and I will post it here on this channel hopefully soon!

The company PUYI INDUSTRIAL is no longer on AliExpress. However, you can still find them if you do a Google search. The specific track you see in the video is called 80-15-108.

Thanks! So I purchased the track from a company called PUYI INDUSTRIAL, located in Shanghai. The specific model number for the track in the video is called 80-15-108.

Thank you!

I originally bought them from AliExpress many years ago, but I don't see them on that site anymore. However, I did find their company here: pytracks.en.hisupplier.com/product-2408351-rubber-track-for-small-robot-80-15-108.html Same tracks as mine, hope this helps!

I performed a stall torque test on one with 15 volts and it had produced around 73 foot pounds of torque or about 99 newton meters. The rpm if I remember correctly was around 150 rpm at the same voltage. Accounting for efficiency losses, it's safe to say you can almost double these figures if you double the input voltage.

@@Brute4rce1111 wow!! That's pretty dang good. Especially at stall for a 1 phase motor of this size. Rpm is a little low but that's fine.

This is the same manufacturer I got them from. I can't find the exact type of track I got, but they are very helpful in sizing any type of track to your exact needs. Hope this helps! m.it.aliexpress.com/item/32262340655.html?trace=wwwdetail2mobilesitedetail

Thanks Chris! The supplier of the tracks is called Puyi Industrial, located in Shanghai. They came with the two uhmw drive sprockets and idler wheels

@@Brute4rce1111 I know them! They supplied the tracks for one of my ugvs! Keep up the good work!

@@Brute4rce1111 Hello Bruce. I checked the Puyi website but couldn't really find the same setup you ordered. Could you provide your order details? Your choice looks perfect for my project

@@markpatzelt5861 I have bought these tracks about 4 years ago, so things have changed on their site and on AliExpress. However, I was able to dig up old emails on this order. The track is called 80-15-108. The lady I dealt with is Alice Zhang. She is very knowledgeable and friendly and can accommodate any track length you may need. pytracks.en.hisupplier.com/product-2408351-rubber-track-for-small-robot-80-15-108.html At that time of purchase, track was $80 per track so $160 for both. They offer bogie wheels and drive wheel which are sold separately. Drive was $45 and idler was $38. Also account for shipping. Of course I'm sure prices have changed since then, but I'm sure they are negotiable. Hope this helps!

Thank you! They were pulled from a Jazzy Pride power chair. Each one is about 550 watts

I don't sell the shafts, but you can contact PUYI INDUSTRIAL for the tracks. Just search PUYI INDUSTRIAL on Google and you will find them. The specific track you see in the video is named 80-15-108. The company used to be on AliExpress back when I ordered from them but it appears that they are no longer on that site.

The wheels are made of ultra high molecular weight polyethylene. It is a very durable, impact resistant plastic that has very low wear properties. The tracks are just regular rubber reinforced with kevlar.

I picked it up from my local metal supply store called 'Indusrial Metal Supply.' they have a scrap area in the store where I found it.

They used to be on AliExpress but are no longer selling on that site. However, it looks like they are selling on other e-commerce websites such as here : www.google.com/amp/s/m.made-in-china.com/amp/product/Rubber-Track-80-15-108-for-Small-Robot-Wheelchair-Vehicle-756737365.html.

Yes! For my application, it has a higher flexural strength compared to alloy steel. Also, it will not rust when subjected to mud, water etc. It also has the bonus of reducing some weight 👍

The ones I used for this project are called 'Jazzy Pride' power chair motors. These often sell as a pair for less than $100 on eBay, that's where I bought these from.

The mill is a Grizzly G0704 and the lathe is a Harbor Freight 7x10 with an upgraded, longer 7x16 bed. Both machines have been upgraded with some modifications . The lathe has new tapered Nachi spindle bearings, steel headstock gears, steel QCTP, and a couple other mods. Mill also has new spindle tapered Nachi bearings, speed controller, 2.3 HP treadmill motor and custom turned 2:1 belt and pulley reduction. Eventually someday, I would like to convert it to full CNC ☺️.

@@Brute4rce1111 Thank you, building a motorized track platform to move heavy objects around the yard. I will look at your video a few more times to pick up on a few details. I might have to use more powerful motors. What is the max load for you platform?

@@antonioubach2530 That's awesome! So the max load I plan on moving is going to be around 400 lbs. Theoretically, it could move more but we will see haha.

Hey thanks! The three wheels act like roller bearings for the track, and as such are not directly powered by the motor but they spin in place. The robot will eventually be powered by a 24 volt 30 AH lithium battery pack that i still have to buy. The motors will be controlled by two 60 amp electronic speed controllers with basic radio transmitter and receiver. I weigh about 63.6 kilograms and the robot is designed to carry a total mass of at least 100 kilograms. To calculate power and voltage was nothing fancy, I just needed 24 volt motors to mate with the 24 volt speed controllers that I already have. To account for force required to move a 100 kg mass, I looked for motors that could achieve twice that. In this case, wheelchair motors are all over eBay and local garage sales for very cheap. They also operate at 24 volts with 100 percent duty cycle and with rugged built in gearboxes. They also are made for moving sometimes very large people over steep inclines without drawing too many amps. They would draw about 30 amps max at stall but would only consume a few amps when carrying a 30% load. Whenever I design a project like this, I usually double the maximum real world forces I would realistically put on the robot and find an appropriate motor that matches those performance requirements. Hope this helps :)

@@Brute4rce1111 Thanks for the answer.Greetings from Indonesia and have a nice day.

So it seems that the original seller PUYI INDUSTRIAL is no longer on AliExpress. However, you can still find them on other e-commerce sites. The specific track I bought is called 80-15-108. Here is a link to that specific set of tracks: pytracks.en.hisupplier.com/product-2408351-rubber-track-for-small-robot-80-15-108.html The company is more than willing to help you out, just reach out to one of their sales representatives and tell them exactly what you want. Hope this helps!

I'm sure anyone could buy of the shelf pipes or other shafts that would fit the wheels. However, this machine will see lots of heavy loads and I didn't want to take any chances of the shafts bending under heavy loads. I wanted the shafts to be as strong as possible, which is why I machined them out of titanium. Titanium has a much higher tensile and flexural strength compared to steel.

I got them on eBay. They are 'Jazzy Pride' brand power chair motors.

It is a common safety practice to never grab the metal shavings of anything coming off any stock that is being machined. In some cases, It could really cut you badly if it snagged around your hand 👍

@@Brute4rce1111 Thanks for clarifying. Makes sence
