Can Anyone Here Could Help Me…..?
I am a 3rd yr. COE and i want to begin making my thesis as early as now.. I plan to make Robotical Arms with the ability of changing its gear on different types with different kinds of function but my idea doesn’t stops here because i am thinking of making an arms for mainly using lasers and together with it’s security parameters to avoid accidents..This arm i want to make is mainly for dissecting very delicate stuffs “with” accuracy and efficiency.. of coarse, what i am thinking needs a long time of planning thats why i prefer on starting now..
Guys… Engineers and Non Engineers..
1.) What do you guys advice me as early as now.
2.) And is it possible that i could buy laser(real lasers which burns to dissect ) on the market with a affordable price or i should even make my own???
Please Help me Guys, I really want to achieve this.
First, you need to learn about laser cutting.
Second, you need to learn about control systems. Stepper motors are quite popular in the robotics area, as they provide a high level of accuracy when moving from one point to the next, and can complete these moves rather quickly.
Third, you will not be able to build a fully functional model. Industrial lasers used for laser cutting are about $8000 each. I would recommend building a prototype, and use everyday “pointer” lasers to demonstrate your goal. Furthermore, new stepper motors are kind of expensive, especially if you want high accuracy.
Lastly, you need to clearly define what you are trying to achieve. From your question above, I can see you have an overall vision, but in order for your thesis to be successful, you need to clearly define one aspect. You can’t do everything at once, especially within your time frame, and trying to reinvent the wheel is only going to leave you frustrated and disappointed.
