Inexpensive Tactile Sensors for Robotic Hands

TakkTile's technology leverages MEMS barometers to deliver 1-gram sensitivity for a fraction of the cost of existing systems, in a package durable enough it can survive being hit with a baseball bat. From original research paper:

A new approach to the construction of tactile array sensors based on barometric pressure sensor chips and standard printed circuit boards. The chips include tightly integrated instrumentation amplifiers, analog to digital converters, pressure and temperature sensors, and control circuitry that provides excellent signal quality over standard digital bus interfaces. The resulting array electronics can be easily encapsulated with soft polymers to provide robust and compliant grasping surfaces for specific hand designs. The use of standard commercial-off-the-shelf technologies means that only basic electrical and mechanical skills are required to build effective tactile sensors for new applications.

For $299 the TakkTile Starter Kit includes two TakkStrips cast in rubber and a Arduino Micro.

3D Vision: Ensenso B now also available as a mono version!

3D Vision: Ensenso B now also available as a mono version!

This compact 3D camera series combines a very short working distance, a large field of view and a high depth of field - perfect for bin picking applications. With its ability to capture multiple objects over a large area, it can help robots empty containers more efficiently. Now available from IDS Imaging Development Systems. In the color version of the Ensenso B, the stereo system is equipped with two RGB image sensors. This saves additional sensors and reduces installation space and hardware costs. Now, you can also choose your model to be equipped with two 5 MP mono sensors, achieving impressively high spatial precision. With enhanced sharpness and accuracy, you can tackle applications where absolute precision is essential. The great strength of the Ensenso B lies in the very precise detection of objects at close range. It offers a wide field of view and an impressively high depth of field. This means that the area in which an object is in focus is unusually large. At a distance of 30 centimetres between the camera and the object, the Z-accuracy is approx. 0.1 millimetres. The maximum working distance is 2 meters. This 3D camera series complies with protection class IP65/67 and is ideal for use in industrial environments.
