Real-time behaviour synthesis for dynamic Hand-Manipulation

From Vikash Kumar at University of Washington: Dexterous hand manipulation is one of the most complex types of biological movement, and has proven very difficult to replicate in robots. The usual approaches to robotic control - following pre-defined trajectories or planning online with reduced models - are both inapplicable. Dexterous manipulation is so sensitive to small variations in contact force and object location that it seems to require online planning without any simplifications. Here we demonstrate for the first time online planning (or model-predictive control) with a full physics model of a humanoid hand, with 28 degrees of freedom and 48 pneumatic actuators. We augment the actuation space with motor synergies which speed up optimization without removing flexibility. Most of our results are in simulation, showing nonprehensile object manipulation as well as typing. In both cases the input to the system is a high level task description, while all details of the hand movement emerge online from fully automated numerical optimization. We also show preliminary results on a hardware platform we have developed "ADROIT" - a ShadowHand skeleton equipped with faster and more compliant actuation... (website)

Service Robots Use Flat Motors

Service robots being designed for the disabled must be reliable, safe, and easy to use. Having the right motion system components is essential for these highly specific applications.

BLE2 Series Brushless Motor & Driver

BLE2 Series Brushless Motor & Driver

The BLE2 Series replaces our popular BLE Series and continues our brushless motor advantages by featuring an all new compact, high-power and high-efficiency brushless DC motor combined with a Driver that can be digitally set and controlled via external DC voltage or by the front panel. The BLE2 Series can easily compete with larger 3-phase inverter driven motors in many more applications, with built-in simple holding torque function, saving space and increasing performance thanks to the advantages of a brushless motor design. The BLE2 Series has a maximum speed of 4000 r/min, achieving a speed ratio of 1:50 (80 to 4000 r/min). The new motor structure is small than previous models and enables high power and high efficiency while incorporating easy setting, installation and wiring. The new motor connector offers IP66 degree of protection and allows for easy and direct connection between motor and driver with two available orientation of cable outlet direction.
