4 DoF mechanical arm mounted on a tripod
We want to design an arm which can be mounted on a tripod as shown in the attached image. The total length of the arm is going to be 1.5m from pivot to end effector. For the movement of the joints please refer the other image. The total weight of the arm and the mechanism has to be less than 3kg. The payload is going to be less than 300 grams.
Your job is to design the underlying mechanism which can drive this arm as smoothly as possible. The deliverables are going to be CAD of the mechanism and BOM and anything else which will be required to prototype the arm.
The project will only begin with this contest and the designer will be hired for continuation of the project.
Roller Mop
This is for a new mop invention. I was able to make a somewhat functioning scaled model of just the internal mechanisms as seen in the attached video.
Taking from the carpet sweeper seen here: http://bit.ly/32vqkGF, I want it to have 3 sponge rollers that spin in alternate directions at an accelerated speed (3:1) so that when it is pushed across the floor, the sponge rollers spin to mop up a mess.
I used gear pullies to spin the rollers, however, I am open to any kind of gears based on your expertise for efficiency, durability, efficacy, and cost of goods. This will be a retail product and I would like to keep the price competitive with sweepers.
Please provide the following:
- Completed product with retail-ready design
- Full size (similar to the carpet sweeper)
- Rollers should have push pin or equivalent to easily pop rollers in and out (they will be replenishments with a variety of roller options (i.e. brillow, sponge, brush, shammy, etc.)
- It should break down to fit into a retail box, again similar to the carpet sweeper link provided.
- Rollers are 1" diameter
- Wheels are 2"

Mechanical SolidWorks CAD Project
We are looking for a process diagram and a solidworks drawing of a complete pump station. All of the detailed submittal sheets will be emailed. A complete understanding of mechanical equipment will be needed in order to complete these drawings. Please feel free to ask questions. Examples can be provided.
For this Job the pump station must fit underneath the cooling tower. We are providing the cooling tower stand as well. The height of the stand will be defined by the tank height along with the cooling tower return line (bottom outlet) being routed into the top of the tank. The pump station can extend outside of the cooling tower stand in the Length dimension, but must fit in within the Width.
We would like to identify a couple of resources to work with long-term on multiple projects. Let me know if interested and I'll send the submittal sheets so you can provide an accurate quote.
Thanks,
Jason
