iHY, the Low Cost Robot Hand

The iHY Robot Hand is the result of the DARPA Autonomous Robotic Manupulation(ARM) program. the aim was developed with the goal of producing a low cost robotic hand with the flexibility to handle different situations.
The hand is equipped with three fingers that are flexible and able to pick up large objects like a basketball to a small object like a pin. It’s able to sustain the weight of a 50 lb kettle bell. It can open doors, pick up a power tool before operating the power tool with it’s finger. It is a very versatible hand at a very low price. It has contributed greatly to the field of robotics in a big way.
The hand is underactuated and called so because there are fewer motors than joints. The spring like material and mechanical linkages connect the rigid parts of the finger. The design of the finger enables it to grab and hold large object but yet also grasp small objects like a pin. Have a look at the video to see it at work. This is not the first underactuated finger in the market but it is the first with it’s versatility and at that price point.

iRobot has done a great job and they did not do it alone. They had the help of Harvard and Yale, hence the name – iHY.

The new Care-O-bot 4

This is the new Care-O-bot is now configurable and still compatible with ROS. It has been given a modern look with newer features.

This fourth generation has many of the features available on Willow Garage’s PR2 and it has the same intelligence as the PR2 given it’s on the ROS platform. It has learnt from PR2 that you can’t sell the entire robot as it’s too expensive. It has the options to purchase the robot with different configuration depending on your budget. Something worth looking into, given it’s german built.
