From 7Bot's Kickstarter campaign:
In 2014, two of us co-founded project uArm with other two makers. There we received a lot of feedback from our Angel backers:
More axis for more powerful applications, and more controlling dimensions (force control, speed control and flexible-joint).
More rugged material rather than Acrylic, muscular servos hardly to be burned out.
More intelligent API. Better inverse kinematics and path planning algorithms to make the movement more precise and smooth.
More accessories and various of end-effectors.
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.
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.
If you have two 7Bot Arms, you can build this amazing Humanoid robot -7Bot Arm Dual:
Estimated shipping date is January 2015... (7Bot's Kickstarter campaign)
IPR Robotics offers a wide range of servo-driven 7th axis linear rails for industrial robots. These rails come in ten different sizes and are constructed from modular high strength extruded aluminum sections to handle payloads of 100 kg to 1600 kg or from steel to handle 2000 kg payloads. This variety of rail sizes allows each application to be sized correctly, controlling the space required and the price point. The drive train design of these rails utilizes helical gear-racks and is proven over 10 years to be repeatable and reliable, even in tough foundry applications.
