Omnidirectional Track Base

This is a very really interesting platform. It has the capability of a tracked base with omnidirectional track base capabilities. We typically use tracked robots as they are able to overcome various obstacles and handle even stair climbing. But there isn’t any track base to date that has omni directional capability.

This omni-crawler is from Osaka University and was developed using the omni-ball concept. The omni-ball design is made up of 2 hemisphere which rotates independently and it also rotates around the ball’s axis which allows the base to move as an omni-directional platform. They have plans to use this concept to develop an interplanetary explorer. This is certainly useful for mobile manipulation in different terrain (indoor or outdoor). I will be tracking the progress of this development closely.

Autonomous Golf Cart from NUS

National University of Singapore(NUS) is working on developing autonomous vehicles that can be used for urban systems of the future. The aim of the project is to achieve autonomous navigation with the lowest cost allowable without sacrificing the robustness and reliability of the system.

This is autonomous golf cart equipped with 3 LIDAR on the vehicle for feature detection, curb detection and obstacle avoidance. Other sensors used on the cart are is the camera and the odometry system. This allows the cart to localize it’s position and navigation autonomously. The video shows the cart has the ability to perform SLAM and handle human traffic in a low traffic place like the university.

The Google autonomous car has set very high standards for autonomous navigation with features within the system to plan it’s actions at road junctions and real life traffic conditions. This might come at a high cost given the sensors that are used on the google car. NUS hopes to lower the cost of development. There are uses for autonomous vehicles within pretty controlled environments like university campuses and small towns.
