The Adroit MK4 arm system uses HDT's next generation of high power density, modular actuators and accessories for human-scale robots.
Completely scaleable, Adroit MK4 arm systems can be configured from single arms with three degrees of freedom (DOF) to 25 DOF dual arm systems. Link lengths and arm configurations are modular and can be customized to each application. Arm systems are water-tight and can include mounting rails for accessories.
MK4 actuators have a power density several times greater than competing drives. Three levels of drive torque from 180 Nm to 500 Nm allow for lightweight efficient assemblies. All variants have integral control electronics, position sensing, torque sensing and continuous rotations. Swapping out drives or links requires only a single open-end wrench.
Several end effectors are available, including force-sensing single DOF pincers. Mounting kits for many robot chassis are available now.

While single arm systems can be very effective, dual arm systems can perform operations such as using one end effector to pick up an object and hold it in position, while the other end effector picks up a tool and uses it on the object
HDT’s Adroit® dual arm systems closely match the dexterity, strength, and speed of human workers without becoming tired or distracted
Every actuator in the dual arm system has true force sensing and absolute position sensing
Arms can be driven joint-by-joint or through endpoint control
Commands can be given to the arms based on position, speed, or force
Variable impedance is available in all modes,allowing the arms to have a wide range of compliance
First advantage of compliance – the arms are inherently safe for people to work around. If a robot and a person bump into each other, the robot’s compliance allows its arms to “give”, just like another person.
Second advantage of compliance – the dual arm system can easily pick up a box or other large, heavy, or awkward object. Just like a person, the robot’s arms can press on either side of the object with the minimum force needed to grasp it, and then move the object to another location.
Motion is smooth and grasping force is constant due to internal loop control of every actuator running at 500Hz
Adroit dual arm robots can be built in a variety of configurations, due to the modular nature of Adroit actuators and the wide range of torque ratings available
Adroit actuators are environmentally sealed enabling operation across a wide temperature range and rough outdoor settings
The performance and low cost of Adroit systems make them very attractive for a wide range of commercial and industrial applications
