Robot Lawn MowerBlind

Contest Ended, Winner(s) have been selected.
I am looking for the industrial design of a robot lawn mower. I would like a product that looks distinctive. There are two main components, a robot and a base station. I imagine the robot to be around 12" x 12" x 8". The robot can dock with the base station. I like the idea of a white, orange, or black design, with the simple robot's logo image:

Here are some robot mowers currently on the market:

I've attached an idea I had of what this may look like, but I'm sure you can do better.

I will award the 1st place price ($1500) to the best overall idea that meets or only needs minor polish to meet all the requirements.

I will award the 2nd place price ($500) to the best idea from an innovative and distinctiveness standpoint regardless of whether it meets the requirements.

I will try to provide feedback as regularly as possible. I recommend starting with low fidelity ideas and getting feedback before refining them. Towards the end of the contest, I will run a survey with around 100 users.

I would prefer SolidWorks 2015, but am willing to deal with another format for a great design or designer.

This contest will be short. I understand if the final designs are a little rough as I expect to continue refining them (ideally with your help).
See above. For the 2nd place price, I will only evaluate based on how innovative and distinctive your design is.

I've tried to give a menu of options where possible for the full requirements. If any of these seems unreasonable, feel free to challenge me on the need for it.

The full requirements for the 1st place prize:
* Manufactured using injection molding with minimal mold complexity.
* The frame needs to have room for a small LCD touch screen, ideally behind a door that flips open.
* The frame will need bump sensors on the front and back, so should have some type of a bumper.
* There should be 2 drive wheels between 6" and 8" in diameter. They should be directly mounted onto motors that are 1" in diameter and 2.25" long.
* The 3rd support should either be 1 to 2 caster wheels 3" to 4" in diameter or skids.
* There should be 1 x 5"-6" blade, 2 x 4"-5" blades, or 3 x 3"-4" blades. When driving straight, the path of the blades should overlap between 0.25" and 0.5".
* The deck should include 1" more diameter than the blade and should sit 0.5" off the ground.
* The deck may be adjusted up 3" until the top of the deck is 5" off the ground.
* A 1.5" diameter and 2.5" length motor will attach to the deck above each blade.
* There will be cameras mounted around the height of the top of the deck in front and in back. The front camera needs an unobstructed view of a 4" strip in front. The back needs a and 2" strip behind the robot. Ideally this space would be inside the frame.
* When docked with the base station, the robot will need to charge using an electrical connection.
* The robot will need approximately 15 square inches of circuit board space between a front and back circuit board. The boards will need to be positioned based on the viewing requirements above.
* The base station will need approximately 6 square inches of circuit board space.
  1. SolidWorks (2015)

Hi Everyone,
I just wanted to give you an idea of what the next steps will be. Tomorrow morning around 8:00 am pacific standard time, I will stop accepting new entries. Around 10:00 am pacific standard time, I will kick off a survey of potential customers. It will run for 2 days or until I have enough responses. I will couple this data with my opinions and will award the winners Wednesday. Thanks for all your help!

Due to computer errors, I can not upload any more files. My computer died Lol, and am fixing it right now.

Sorry for the inconvenience.

In my requirements, the discussion about blade overlap is not clear. The deck should isolate each blade. It is the paths of the grass cut by the blades that should overlap when the robot is moving forward.



Mon, 25 May 2015 17:38:39 +0000
Mon, 25 May 2015 14:42:57 +0000
Yes. I will want source and STEP files.
Mon, 25 May 2015 14:35:05 +0000
Can we use other software instead of Solidworks?
Upon submission the design will be converted to STEP/IGES....
Is this acceptable?

The cameras identify the edge of the grass and other obstacles. I envision them to be pointed directly down, but they could be raised a few degrees. They should be mounted at least 5" off the ground. Based on the speed of the robot, they need a clear view at least 4" in front so they don't miss anything in front of the robot. The camera in back is less critical, but should have a clear view of at least a 1" and a mildly obstructed view of 2". Ideally these cameras would not be visible from the top, but instead would be hooded by the frame.



Mon, 25 May 2015 13:23:24 +0000
Simple Robots,
Could you be more specific about the camera function? or just rephrase: "The front camera needs an unobstructed view of a 4" strip in front. The back needs a and 2" strip behind the robot. Ideally this space would be inside the frame."

Thank you

I've added 4 more days to the contest. I know it's tight, but I'd rather not extend further. Thanks for your work.



Sun, 24 May 2015 22:02:30 +0000
Wait for my entries please

Some things I missed while writing the brief:
1. The LCD screen should be 42.7mm x 59.3mm.
2. The user should be able to easily carry the unit. Ideally while they can still clearly see the LCD screen.
3. The cameras should be pointed down. Ideally they would not be visible to the user, but would be hooded by parts of the frame.

Hello Simple Robots,

I have just submitted a design for your consideration. All components in the design are of the dimensions you have specified in the brief. I am still working on the base station for the product but wanted to submit something to hopefully get some feedback. I would be happy to discuss the design in more detail if you would like to send me a private message.


Sun, 24 May 2015 03:15:35 +0000
Mohamed, How long do you suggest? I do understand that I will get results that are a bit rough.

Mostafa, The idea is that the cameras need to see a space in front of the blade(s) and behind the blade clearly. The 4" and 2" are based on the proposed maximum speed of the robot so successive frames will overlap appropriately when the robot is moving at top speed.

can you extend the deadline since , it is very short time ti accomplish this design
Sat, 23 May 2015 20:35:16 +0000
can you please be more specific about the 4" and 2" strip camera because i really dont get it

American Modern Twyst Plate Apparel Fastener
I am looking to create a new type of apparel fastener. The basic specifications that I am looking to achieve are as follows. The fastener consist of two parts 1. The Plate: (connected to a backpack for example) 2. The Disk (connected to a flashlight as an example... which inserts to the plate to create the fastening/lock) Plate Specs: 1. Size: no more than 17mm x 17mm with a depth of 2-2.5mm thick 2. Needs to be able to house a 12mm round (disk) that will fasten into it. 3. Pounds of pressure to insert disk: goal of 10lbs or less 4. Weight that it needs to be able to hold 100 lbs 5. Pounds of pressure to release disk, 10 lbs or less 6. Functionality: Ideally the fastening system would be push in with a 20-25 degree or less "twist" out. Needs to have the ability to "lock" (lock in this case means, not release so that the user can trust the fasteners ability to hold the objects that are attached to it and they will not fall off. 7. Ideally, the plate can accommodate the separation of the insertion force of the disk from the rotational force that allows the disk to release so that it can be placed on different weights of material. DISK 1. The disk can not exceed 12mm in diameter/size and needs to be 3mm (or less) in thickness. 2. The disk will be attached/mounted to a different object that will hold that object to the plate. 3. Ideally requires 20-25 degrees or less of rotation to release from the plate 4. Ideally it can accommodate a straight "snap in" insertion, or a "ski-binding" toe to heel or side to side snap in. A good concept to look at for inspiration is the clips bike peddle. MATERIALS: Open to anything USABILITY: Needs to be able to handle the wear and tear of at least 100,000 insertions and releases without losing its strength. MECHANISM: I am open to any form of mechanism including (but not limited to) electric, magnetic spring, rings, teeth, gears, pins etc. LOOK AND FEEL: Modern American style (think Apple), needs to have clean lines, nice smooth face, with a beveled edge etc. as It will be used on a fashion/apparel product. INSTALLATION: The design needs to consider how the factory will install both the plate and disk onto to their respective materials/accessory.

Hi. I urgently need to make the design and visualization of the apartmens. We are ready to pay good amount if the designer/visualiser will work as long as you need. We have a model of the building, I attached it to all files. Also there is a small notes from us. There will be 3 angles: the interior angle and two exterior images. The notes are quite simple, but we want to see your ideas as a designer. The style is modern or minimalist. I would like to see cozy design as well as photorealistic visualization. We attached some images which will serve as a good example. The time frame is very limited, the project should be with me by Friday evening 30.10.2015 after 13:00 (UTC+01:00). Use common sense in the work. Write in comments and private messages. Good luck!
Connection/Plug-In system
Description: We are looking for a design of a connection/plug-in system. The system should consist of two main components; 1. The “Base” Which will be mounted on a surface (e.g. wall). 2. The “Contra-Base” The Contra-Base is an adaptor (to which an accessory is attached - e.g. a spot) to click/snap/slide onto the Base. Note: Accessories could weigh up to 1 kg (possibly in a bumpy environment), which needs to be taken into consideration into the design of the “Base” as well as the “Contra-Base” The Base: 1. Should preferably have a round shape with a diameter of approximately 7 cm and be as low in height as possible, without interfering with the design requirements. 2. Will be connected to a 12 volt power point • The 12 volt wire comes either from behind (through the wall) or from a side (on the wall) 3. Wires should be easily connected to the bottom of the Base. • The design should take into account easy attachment of the 12 volt wire to the Base by the user. • Also in case the wire is connected from the side of the Base there should be an opening / gate. 4. Will be fixed to a surface using screws. • The design should take into account easy accessibility for the user when mounting on surface. 5. Will pass 12 volt current to the Contra-Base once the Contra-Base is fixed onto the Base through a solution that is: • Low tech • Full proof The Contra-Base: 1. Should click/snap/slide/connect (or other) onto the Base; • Once attached on the Base, the Contra-Base should only be able to disconnect through manual intervention; • The locking mechanism should be very solid and as low-tech and full-proof as possible; • Once locked, the Contra-Base should not be able to turn on the Base, however the placement of the Contra-Base should not be limited by a (single) defined position; • Release mechanism should not be by force, but by intervention. Again, the solution should be as low-tech and full-proof as possible. 2. Should receive the 12 volt current from the Base (see “Base” #5.) and forward it to the accessory (e.g. spot) mounted on the Contra-Base. Requirements: 1. All solutions need to be manufacturable and preferably seamless integrated if possible; 2. To be manufactured using injection moulding with minimal mould complexity; 3. The files should be of a professional quality (including STEP files) so they can be handed over to an Injection Moulding company; 4. Non injection components should be minimal and easily available in the market or easily manufacturable; 5. Modern, minimalistic but high quality look & feel is an absolute must. Also when the Contra-Base is not attached to the Base, the Base should still look good and not technical. Please provide High Quality rendering views + preferably .U3D files during the contest. STEP files required on completion We will award the 1st price ($1500) to the best overall idea that meets – or only needs minor polish to meet – all the requirements We will award a 2nd price ($500) for the best innovative idea for the easy connection solution of the 12 volt wiring to the “Base”. • Needs to be integrated into the design of the “Base”, as low tech as possible and without any complex (expensive) external components. We will award the 3rd price ($500) to the best innovative idea for the 12 volt current transfer solution from “Base” to “Contra-Base” • Needs to be integrated into the design of the “Base” and the “Contra-Base”, as low tech as possible and without any complex (expensive) external components. Attachments: Whiteboard screenshots: 1. Potential Wiring situations; 2. Electrical wire connection to the “Base”; 3. Fixation of “Base” to wall; 4. Fixation of “Contra-Base” to “Base”.
