We are in the startup to make a small device that shall shake medical samples up and down 50-60mm with adjustable speed an adjustable speed. We need some inputs on how to solve the mechanics on moving our holder that holds the samples. A simple sketch with some products that can be used will do. If the cooperation works, we want to use you to design the complete product. The solution needs to be cheap and use mostly easy to acquire shelf products. The product is portable so it needs to be compact. - Speed 0.1-5 shakes per sec. - The samples have a maximum weight of 2kg. We have the possibility to add a lot of electronics, so the solution can have a complex motor controller if needed. If you have what it takes, let me some reference of your previous work and tell me why we should choose you.

Hi, I am a Mechanical engineer with a masters degree in control. I am currently teaching statics, mechanics of machines and control courses in an engineering University. I have done these kind of projects before and I have many fine BE students. We can even work on a long time project. Because of my expertise in machines and control I guess I will be the best choice for this kind of work. Regards, Hassaan

Dear Buyer, I have reviewed you request for proposal and viewed the attached document enclosed with this post. Based on my study you require to design a simple mechanism so that a linear motion can be provided to the samples. After finalizing it you require to design it in a cad software. I have prior hands on experience in designing a robot which I have attached in my profile. Kindly go through it once which will help you to evaluate my competency. I would appreciate if you could provide us with further information like the drawing having dimensions of the parts of your robot. so that we could discuss the same in our further meet. Please let us know if you require anything from our end which will help you to take decision for your project. Regards Paramjeet Singh

Hello, You only need a cam, guides and a gear motor. But, 2kg at 5 shakes of 60mm per secod is not going to be a small motor. That is a lot of forece for a portable device, and that amount of shaking will likely cause a lightweight device to jump around. You can complicate the device using ball screws and such, but that will require larger motors and not eliminate the jumping problem at high speeds. If pneumatics are an option (not likely for a portable device) you might get by with a single guided cylinder for a minimum-hassle system. I would guess you will need electronics/controls for speed and time/number of shakes. Instead ot shaking, is tumbling an option? And do your containers have a secure locking mechanism available? Best regards, Stuart Borden.
