We have upgraded our Turtlebot2 to ROS Noetic on Ubuntu 20.04. The Turtlebot2 was previously running on ROS Kinetic. . In the video above, the Turtlebot2 was mapping out the office floor of the School of Digital Science, UBD. It was controlled wirelessly with a PS3 controller. The video has been speeded up x2. Turtlebot2 […]
The bumper of one of our Turtlebot2 was jammed. The center and left side were jam and could not push in. It turned out that the fixture for center bumper mechanism came out of its holder. It was probably pushed up too much. It is now fixed. Kobuki has gone out of production and it
Hafiq’s Deep Reinforcement Learning-based robot is doing well in crowd navigation. The DRL model was trained in one crowd setting and tested in different unseen crowd settings. In simulation, we have tested with up to 12 moving obstacles at a speed close to the robot. In real-world, we have tested with 4 obstacles at a
The battery pack of the NAO robot has “intelligent” charging circuit that prevents the battery from charging when the battery’s voltage falls below a set value. This would deem the battery useless and call for replacement. Our NAO was idle for about two years when restriction on physical activities was in place due to the
The School of Digital Science has acquired a Niryo NED 6-DoF robotic arm. This added opportunities for us to experiment with manipulation tasks in robotic. The video below is our first project with the NED. This is a lab project by three third year students in the Bachelor of Digital Science: Firdaus, Luqman and Farah.
We are working on the Niryo NED 6-DoF robotic arm that the School of Digital Science has recently acquired. The RPi firmware that came with the NED is an older version and is not compatible with the latest version of Niryo Studio, 4.1.0. So, we upgraded the firmware to 4.1.0.

The Covid pandemic second wave hit the country at the beginning of this semester. I was stuck in how to get going with the SS-4311 Robot Programming module where the students are supposed to have fun with the physical robot. Fortunately, there are just the sufficient number of robots for all the students. They have
This time we are using the Alphabot2-Pi from Waveshare. It would be good to have fitted with an ultrasonic sensor, IMU and wheel encoders.
