Not good enough anyway. You'd have to combine this with something else to improve accuracy.

I usually don't help with homework but...


You could fabricate a roller to print alignment points all over the material before it is cut, then use a similar system to as the Origin to track it. The trick then becomes keeping the roller aligned when printing. But you are doing this step when you're not cutting. Your materials cost has to be low so you have to make up for it with your labor and coding time.

Apparently it is! Neat school. Not sure what else they are giving him for free if his budget is so low.

"I’m based in India and this is my Under Graduate level project and I have three other team mates. We have been assigned two project guides from my college. The project is funded by a consultancy and the initial budget is INR 1 lakh. I want to complete it in the next 3-4 months. I have a little experience with mechatronics and robotics"

100,000 Indian Rupee equals 1,340.29 United States Dollar. That is only a few hours of consulting time, a pile of used parts or 6 tons of steel.

Scrap price, since they need to get lucky and spread those Rupies over as much as they can get. Who can afford new steel?

Umm the thing is that I also get stuff for less over here. Right now I'm practically looking at getting the bot working with 4 wheel drive with 2 external encoders. Depending on the results after tuning, I may add another set of rotary encoders and do a dual feedback loop.

Another idea to lower cost is to mount cameras on the bot and have a grid system overhead. The grid would give the bot references closer together than just using mirrors for lasers or just the perimeter as a reference.

It's like trying to measure the speed of the boat by only reading the RPM of the propellers.
