7Bot: a $350 Robotic Arm that can See, Think and Learn!

$290,962

606

Robot arm is always considered geeky and pricey. One of the most popular robots, IRB 2400, will set you back $50K+ and you will need an engineering degree to program it.

We believe that robot should be for everyone. So we developed a miniature of IRB 2400 at half the price of an iPhone. And you don’t even need a single line of code to teach it how to move!

Learn by holding its arm

Teach it like a child by holding its hand, and it will replay precisely.   A robot called Baxter can also record and replay but it costs $22000.

Grandpa (who doesn’t even know how to use iPhone) taught it Chinese Calligraphy by holding its arm. Damn, now it writes better than all of us in the team!

Follow your motion, in Realtime

Using leapmotion or kinect sensor, it will just follow your exact motion in realtime.  Again, no coding is needed for you.

Of course, you can still use your mouse or keyboard to control it.  Even over the web remotely.

See and Think

By plugging in a USB camera and using our sample computer vision code,  7Bot can see and think.  Watch how it sorts the lemons by colors.

And it can even read and understand the math, and do the homework for you.  Well, may not be you but your 7 years old kid.

So tell me more about 7Bot, technically

7Bot Arm is a 6-axis desktop robot arm that is able to see, think and learn. It is precise, durable, versatile and intelligent.  

With all Aluminum Body and 6 degrees of freedom powered by high torque metal digital servos with force-control supported, 7Bot has rugged reliability with exceptional performance in torque and speed, even close to the industry robot arm. 

What else can 7Bot do?

When you want to move up the next level in the iPad game but you are getting bored with the current level. You have a helping hand. (The screen wasn't broken by 7Bot, please understand we are saving every penny on the project.)

Rewards

7Bot Basic: Vacuum Cup Gripper

The Vacuum Cup Gripper is one of the most useful accessories for 7Bot. Powered by a 5V Air Vacuum pump and valve, it picks up most objects with smooth surface up to 1kg.  You can use your Arduino, Raspberry Pi or any other micro-controller board to control this gripper through 2 digital signals.

Up to 1Kg of payload
Up to 1Kg of payload

7Bot Pro: Vacuum Cup + Two-Finger Gripper

Human isn't octopus and we are born with fingers.  So we offer the two-finger gripper to grasp objects within 500g payload.  Working stroke of gripper can be justified by replacing its fingers.  We will open source the design of finger gripper so that you can customize it for different application.

7Bot Dual

Human is born with 2 arms and we should treat Robot the same.  That's why we offer 7Bot dual.  By providing two 7Bot Arms, you can build a humanoid with less than 5% of the cost you can source elsewhere. With our computer vision and AI capabilities, 7Bot humanoid can even perform things better than you, like solving for Rubik's cube.

And don't be limited by our imagination, build your humanoid with 7bot and show us what it can do!

7Bot Mobile: Building a Mars Rover

Yes, we have thought of it too! So we proudly provide an omni-directional mobile platform as an option.  Now you can build your own Mars Rover on 4 mecanum wheels using our "7Bot mobile" package at $1397.  Only 25 units are available!

7Bot studio

We open source the drawing of our end-effectors so that you can either customized or just reprint your own end-effectors.  If you don't have a 3D printer, you can choose our "7Bot studio" package.  It includes a 7bot, a 7bot dual humanoid, a 7bot mobile and a 3D pinter!  Only 5 sets are available.

Here's the summary of the rewards tier:

Controlling Methods and Programming API

While 7Bot could provide you a fantastic and awesome hardware, programming a robot is no trivial thing, especially for the users without very strong engineering background. So we offer a various of controlling and programming methods, from very basic level to the most advanced level.

Remote control is the easiest way for you to control your 7Bot Arm.  

Basically, you can use any widely used human interactive device as the controller, from traditional mouse and keyboard, to gesture control devices like Leapmotion and Kinect sensors. You can use a Leapmotion sensor to control 7Bot Arm to follow your gestures, and use Kinect sensors to make the 7Bot ARM dual imitate your movement of upper limb in real-time.

With our embedded inverse-kinematics algorithm, the 7Bot Arm can also be precisely controlled using coordinates. And we have made web controlling application by using a Raspberry Pi as the host and with real time feedback. 

Our custom servos with precise position feedback allow you to quickly set it up and operate in teaching mode without any codes. In this mode, you can simply drag each joint of the robot to a serious of desired way points. The movements will be recorded, and could be replayed in an optimized path. Using teaching mode, you can easily guide your 7Bot Arm performing some tasks.

A multi-platform supported 3D visualization application will be provided for you to manipulate the 7Bot Arm intuitively. With our 3D visualization application, you can easily set and read the position of each joint separately with real-time graphic interface.

The 3D model in the application could be interacted and controlled with mouse and keyboard. The robot can follow the movement in real-time. Or on the other side, you can perform simulation first, and generate way-point with the software, and then download the optimized moving path to your 7Bot Arm. This is well suited for many algorithms that need lots of iterations in simulation, like reinforcement learning. You can get rid of any low-level coding for the robot.

The 7Bot Arm is compatible with Scratch. You can use Scratch Programming Environment to program the 7Bot Arm. Graphical Programming, super easy way!

While for advanced users, we provide a wide range of open-source software APIs in C and c++. We will also open source the design with motion planning and vision supported, for more advanced developing.

Features

All-Metal Design

The mechanical parts are made up with all aluminum body and powered by 6 high torque metal servos providing rugged reliability with exceptional performance in precision and speed. 

6 DOF

With 6 degrees of freedom, 7Bot Arm is flexible and can act just like a real human limb.

Force Control and Speed Control  

Our customized servos with digital I2C interface allow you to set the position, driving force and speed of each joint. PID parameters of each servo could be adjusted separately. Besides, there will be a special flexible-joint mode.

Stability

7Bot beats all 7 of us in the team in balancing the table tennis.

Durability

We attempted to overwork 7Bot within what the labor law allows and filmed the process with an iPhone.  The iPhone refused to work after 30 min by being too hot while 7Bot is still acting diligently.

Development of 7Bot

We have developed 4 prototypes of 7Bot Arm, more than 10 times of hardware improvement. Now the 7Bot Arm is ready to release. The following shows our main prototypes in different periods.

Timeline

November 2014:  Founded 7Bot Team.

April 2015: Finished our first 7Bot Arm prototype. 

May 2015: Improved the movement of the Arm. Tried to use metal servos.

June 2015: Finished the design of 7Bot Arm Dual. Added more accessories, such as the slider and mobile platform.

July 2015: Finished the development of Scratch Library and motion API.

August 2015: Started design our custom-made servo.

September 2015: Look for manufacture partners.

October 2015: Finish the design of the servo.

November & December 2015: Start manufacturing.

January 2016: Start shipping.

Team members

There are 7 members in our team so far:

Eric Wang leads this team on project management and business

Jerry Peng is the electronic and algorithm engineer in the team.

James Wang is the mechanical engineer.

Jiangtao Li is the hardware engineer.

Haoxuan Liang helps on all the operations.

Jamie Yang: Embedded systems geek. Help us with the software part.

Kevin Leung:  Marketing and Campaign lead

Risks and challenges

Our team members are based in Shenzhen and Hong Kong to make sure that we are close to the factories.

It is already our third kickstarter campaigns among our team members. We have gone through all the manufacturing process with our first project, uArm, the previous generation of 7bot, and we were able to ship on schedule. Aother kickstarter project "Muku Shuttr" was even able to deliver before the project schedule and was deeply loved by 2600 backers (please check out the comment section).

Our fulfilment partner Floship has fulfilled dozens of crowdfunding projects and many of those are having thousands of backers.
