Lifting columns for embodied robots add a guided vertical axis. The column can raise a robot body, arm base, tool, tray, camera, or sensor. This helps the robot work at more than one height.
Why a robot may need vertical motion
Work surfaces, shelves, machines, and people are not all at the same height. A fixed robot may use too much arm travel just to reach them. A vertical axis moves the whole work area up or down.
- Adjust the height of a cobot or robot arm
- Raise a camera, LiDAR, or inspection sensor
- Align a tray with shelves or conveyors
- Change the working height of a service robot
Lifting column or linear actuator?
A lifting column has a guided telescopic structure. It can fit upright motion and offset loads. A linear actuator creates push-pull force. It may need a separate guide for the robot load.
The machine layout decides which form is better. Check load, offset moment, stroke, closed height, speed, duty cycle, and mounting stiffness.
Common robot layouts
- Fixed cobot station: move one robot between fixture heights
- AMR or AGV: raise the arm or tray at the work point
- Inspection robot: change the sensor view
- Service robot: reach counters, shelves, or equipment
Selection checklist
- Total moving mass, including tool, payload, and cables
- Center-of-gravity offset and bending moment
- Stroke, closed height, speed, and duty cycle
- Base stiffness and stability at full height
- Voltage, feedback, brake, and control interface
- Dust, moisture, temperature, vibration, and cable routing
Product parameter selection example
Assume the robot arm, tool, and payload have a combined mass of 50 kg. Their center of gravity is 280 mm from the column center. The task needs 650 mm of travel.
Calculate the static force and offset moment first. Then include the approved acceleration and safety factors. Check guide stiffness, overlap, speed, brake behavior, and column mounting.
A mobile robot also needs a tip-over review at full height. This example explains the process; it does not select a model.
Controls and safety
Define travel limits, position feedback, brake control, emergency-stop behavior, and restart rules. Review pinch points and cable movement. The system integrator remains responsible for the machine risk assessment.
See the cobot lifting column guide, embodied robot pillar, and column selection guide for related planning information.
Frequently asked questions
They can raise or lower a robot body, arm base, tool platform, tray, camera, or sensor mast.
A lifting column includes a guided telescopic structure. A linear actuator creates push-pull force and may need an external guide.
Include the robot, tool, payload, cables, fixture, and their center-of-gravity offset. Add the approved dynamic load case.
It can be considered when the base and column are designed for the moving load. Check braking and stability at full height.
Define voltage, feedback, position needs, interface, travel limits, brake behavior, update rate, and fault handling.
