Used
Integrated on ANYmal
This video shows the capabilities of the DynaArm when integrated with the quadruped robot ANYmal. The Integrated system named ALMA has been used in numerous research projects by researchers in RSL at ETH Zurich.
Used for
Telemanipulation
DynaDrive Baboon is used as an ANYdrive replacement of the Hip and Knee joint on ANYmal at RSL ETH Zurich. The gait shown has not been tuned for our robotic joint, demonstrating ease of installation and operation.
Used as
Master and Slave
The robotic arm DynaArm serves as a master device for remotely controlling another DynaArm. The torque sensitivity of each joint in the arm enables precise and versatile motion control. This makes it a versatile and valuable tool for a variety of applications.
Used in
Festo Bionic Assistant
DynaArm has been used on the BionicMobileAssistant demonstrated by Festo at the Hannover Messe 2020 Digital Edition.
Used as
Bartender
Thanks to its easy installation and user-friendly interface, DynaArm was swiftly deployed using the integrated Teach&Repeat method to serve drinks during the open lab day of the Robotic Systems Lab at ETH Zurich.
