This document provides an overview of the improvements to MoveIt Servo as part of Google Summer of Code 2023.

Abstract

The current MoveIt Servo has enabled users to utilize reactive control. However, in its current implementation MoveIt Servo only provides a ROS interface to users. While the ROS interface is very versatile, it can also be a bottleneck for users who need harder real-time performance guarantees. There were also many aspects of the software design of the package itself that could be improved.

Project Goals

This is a live document for the thoughts on new design of MoveIt Servo

C++ API overview

The input to servo at c++ level can be :

  1. Eigen::Vector6f (twist)
  2. Eigen::VectorXf (joint jog)
  3. Eigen::Isometry3d (pose)

The output of servo will be an Eigen::Matrix with 3 rows (position, velocity, acceleration) and num_joints columns (one for each joint)
