I require a design of a machine able to dispense products (that is similar to a vending machine) - to a conveyor belt. Preferably here are the specifications: It must be able to dispense a variety of products in different sizes - however to simplify it can always be assumed it is dispensing a rectangular prism (box). Minimum dimensions are: 100 millimeters x 100 millimeters x 40 millimeters (plus-minus 3 mm) Maximum dimensions are: 500 mm x 1200 mm x 200 mm (plus-minus 3 mm) - Must be actuated via either: stepper motor, servo motor or equivalent (candidate must provide exact make/manufacturer and model number of motors used) - Must be designed to be easily loadable, with the possibility of loading multiples (of the same product, meaning multiples of the same "box", in series). - Must have a dispense rate of 0.2 Hz for a load of 25kg increasing to 1-2 Hz for a load of 1kg (non-linear preferable [ie. getting a higher frequency is of course preferable]). - Use of pre-fabricated components is preferable (such as T-SLOT) where applicable. Control Systems/Motor Drivers and supplemental electronics would be completed by myself and others. If the candidate is interested - they are able to assist in the fabrication process, upon successfully validating their assembly. Candidate would require to build a full assembly in Solidworks or Autodesk Inventor.

Hello. I would like to have the opinion of an engineer on the feasibility of a project. I would like to know if it is possible to create small robots able to move certain parts of their body like the arms and legs, jaw and feet only making work the gears that are used in the older kind of clock. Basically, you give the charge to the body part that you want to move and it lasts for a bit of time, then of course the gears reach the end of their run and stop. The goal is to create small, low-cost robot for use in stop motion animations, which helps to avoid taking a picture to each little movement that we want the charather makes. The starting kind of armature can be something like this : https://www.stopmotionstore.com/index.php?main_page=product_info&cPath=25_22&products_id=463&zenid=d556fb9e4cdbf6866fd7a949b1966e7b but should be modified by applying different sized gears in some strategic parts of the armature. I'm not an engineer at all,so I don't know if it is already be done or if it can be done. For sure I know that I don't want to use electronic and electrical parts for this kind of robot. No servo motors,no system on chip,no battery and so on...but only gears,like this : https://en.wikipedia.org/wiki/File:Gear_reducer.gif ok. let me know.

Overview: I need a setup with vertical vibration, where I could control both amplitude and frequency of vibration. I intend to use a jar containing few substances, mounted on the spindle of this setup, which thus then vibrates. Please check attachments. Firstly the image (jpg) so you get an idea. The 3ds, dwg, obj formats are also attached for your inputs. One image is also shown with a jar attached to illustrate how I intend to use the setup later with jars. Specifications: Amplitude range: Min 1 cm, Max 10 cm, step 1 cm Frequency range: Min 1 Hz, Max 10 Hz, step 1 Hz (1 Hz is one complete up and down vibration cycle) The entire unit, only outside is shown. Inside is up to you on how do you design. The spindle shall have a hole mechanism, so I could tighten with a jar later. The entire unit shall be powered by battery or electric power. The dimensions of bounding box are just for a guide. If you think, you need to make little bigger to accommodate, please feel free to propose. The current consumption of motor shall be within 3A max. I intend to vibrate few powder like substance inside the jar, which due to vibration, would turn to a small bulk , total weight of jar including that stuff inside would be just around 500 grms max. So mechanism shall be sturdy enough to handle this weight steadily. The product can be mix of metal and plastic. VERY IMPORTANT: ALL COMPONENTS SHALL BE DESIGNED WITH STANDARD OUT OF RACK COMPONENTS AVAILABLE IN INDIA UNLESS IT IS VERY UNAVOIDABLE TO HAVE SOMETHING CUSTOM MADE. I am a layman and these are all my requirement. I have given product description. How do you design inside, and get me the result is up to you. You could also come up with the workflow of this project, so that, my expectation is finally met.What I do not want is, you design something finally after spending so much effort, but my requirements are not met resulting in disputes. So there would be review meetings. Output: Mechanical: 3d design files with all details, (typically CAD, 3ds, and also STL if 3d printing would be needed) Electronics: Circuit files, PCB design, Image: Illustrations of look and feel of the product designed. Both inside and outside. Rendering is optional, but at least a normal image export needed like I have attached. Material list with reference to standards (mainly mech components) Attaching the zip file containing all files, as when attached individually only dwg appearing as of now. There is a change needed. The amplitude max range shall be 10 cm, so I am relaxing the box dimensions from 15x10x10 if this change can make the box stable. Please come up with proposal on this as well. For ex, the box could be made bigger in dimensions to accommodate my change.
