Project configuration

Seven-axis lightweight research manipulator

System overview

Built around
your research.

A seven-degree-of-freedom arm for fixed-workstation manipulation and robot learning. Kinematic redundancy, hand-guided teaching and combined force-position control support motion planning, impedance-control and imitation-learning research. Select a left arm, right arm or bimanual setup.

Redundant kinematics: 7 axes
Nominal maximum payload: 3 kg
Nominal maximum reach: 739.45 mm

Configuration, lead time and delivery scope confirmed with your inquiry.

Design & capability

Designed for the task.

More freedom for planning

A seven-axis anthropomorphic arrangement supports end-effector orientation, joint obstacle avoidance and redundancy resolution. Nominal arm mass is 4.3 kg with +/-0.1 mm repeatability.

Hand-guided demonstration

The manual lists gravity compensation, zero-force teaching and trajectory replay at a 100 Hz teaching sample rate. Joint torque-related readings are not direct end-effector contact forces.

Control and research integration

Position, velocity, torque and MIT hybrid control are documented, alongside Python / C++, ROS 2 Humble, MoveIt2, Gazebo and URDF. Confirm interface versions.

Specifications

Configuration details and measurement conditions.

Structure and performance
Degrees of freedom	7
Single-arm mass	4.3 kg
Maximum payload	3 kg
Maximum reach	739.45 mm
Repeatability	+/-0.1 mm
Materials	Aluminum-alloy frame, plastic enclosure
Mounting	Rigid, level fixed workstation; hole pattern per version drawing
Configurations	Left / right / bimanual

Maximum payload depends on pose, tool mass, center of gravity and dynamics. Repeatability is not absolute positioning accuracy.

Joint specifications
Joint	Range	Maximum speed	Rated torque	Peak torque
J1	-60 to +180 degrees	180 deg/s	15 Nm	30 Nm
J2	-180 to +15 degrees	180 deg/s	15 Nm	30 Nm
J3	+/-158 degrees	180 deg/s	15 Nm	30 Nm
J4	+/-110 degrees	180 deg/s	15 Nm	30 Nm
J5	+/-158 degrees	180 deg/s	3 Nm	7 Nm
J6	+/-90 degrees	180 deg/s	3 Nm	7 Nm
J7	+/-158 degrees	180 deg/s	3 Nm	7 Nm

Coordinates, zero positions and signs depend on arm side and driver version. Peak torque is not a continuous rating.

Power, communication and control
System power	DC 48 V; supply rated for at least 6 A with operating margin
Combined power	<300 W
Communication	CAN 2.0, 1 Mbps; USB-to-CAN adapter
External ports	1 power / 1 CAN
Joint encoders	21-bit dual encoders
Control modes	Position / velocity / torque / MIT hybrid
Teaching	Gravity compensation, zero-force recording, trajectory replay
Teaching sample rate	100 Hz
Recorded fields	Joint position, velocity and torque-related data; units and timestamps per SDK

CAN bandwidth and teaching sample rate are not policy inference or end-to-end control frequency. Use the complete-system 48 V supply requirement.

Software and configuration
Recommended environment	Ubuntu 22.04 LTS
SDK	Python / C++, version-specific APIs and examples
Middleware / planning	ROS 2 Humble / MoveIt2
Simulation	Gazebo, URDF and matching controller configuration
Compute	External workstation or cloud service; GPU, models and trained skills not included by default
Temperature / humidity	5-50 C / 35-80% RH, no frost
Noise	<60 dB; source measurement conditions unspecified
Accessories	USB-to-CAN, cables, fasteners and tools per bill of materials
Confirm separately	Power adapter, gripper, tactile end effector, cameras, fixtures, compute and safety equipment

Delivery and validation

Agree on the complete configuration.

Nominal manual specifications, not Actrium measurements. Atlas A7 is a project product name. Force control alone does not establish safe shared human-robot operation. Validate the complete installation and agreed tasks.

Freeze arm side, quantity, end effector, mounting, power and USB-to-CAN configuration.
Provide agreed drivers, SDK examples, models, version notes and license scope.
Verify zero positions, limits, emergency stop and communication-loss handling. Enable the proper mode for hand-guided teaching; do not force an unpowered or braked arm.
Accept recording, replay and tasks under defined installation, load and speed conditions.

Training and deployment

Plan compute for this platform.

Plan GPU compute, model training and hosted inference, with control kept on the robot.
