# Checkmate Leader

Source: https://checkmatedynamics.com/leader.html

[Stations](https://checkmatedynamics.com/stations.html) / E — Systems / E1 | Motorized leader arm

A leader arm that carries its own weight, lets the operator feel the follower’s limits and grip, and returns home by itself. Every joint is a SmartServo G node, the same unit sold on its own.

Fig. 01 — Eight SmartServo G nodes on one Hub 8 Pro: the catalog parts the Leader is built from, as sold. The arm is not shown; links, base and handle are Leader-specific. Concept render.

**01** Operator

## More good episodes per operator-hour.

01

### Weightless

Active gravity compensation at every joint. Operators guide the arm instead of holding it up.

02

### Felt limits

Haptic walls at the follower’s joint limits, and trigger force feedback from the follower’s gripper.

03

### No drift

Absolute encoders hold calibration through every power cycle. No re-zeroing at the start of a shift.

04

### Hands stay on

REC and DISCARD on the handle; the arm returns home between episodes on its own.

**02** Construction

## Nothing inside is special.

The arm is built only from finished Checkmate nodes and a hub. No springs, counterweights or one-off parts. Links, base and handle are the only Leader-specific hardware.

- A spare part is one node on a shelf
- A repair is a node swap, measured in minutes
- Each node ships with its own test card
- Kinematics matched to your follower arm
