This is our new research and development Lab.
We have facilities for 3D printing, mechanics and assembling, electronics and soldering, computing, etc…
It still has no name.
Wanted people wanting to work at/in/on it 🙂
Cheers!
Our prototype of our version of the 3D printed Stanford’s Hapkit V3.0 is now functional. It uses the same electronics and motor. The pulley sizes are the same, however the big wheel has been redesigned to properly attach and support the capstan cable. The support wall has been optimized and reinforced using dual common ball bearings.
A demonstration of the virtual wall implementation is show in the video below.

This is the first test of our build of the Stanford’s Hapkit haptic device built in the School of Engineering of the Universidad de Málaga (Spain) by Juan Gandarias.
This device is intended to be low cost and easy to build, which could make possible teaching haptics, control and telerrobotics all around the world.
In the video, a basic spring model is being tested. Although the motor axis alignment and the friction of the neoprene contact is not perfect,
we are happy with the results.
We used some different components and made some modifications to make it easier to build in Europe. Other changes are coming to make it more robust by using the reprap’s diy experience.
Stay tuned!
Gracias, Juanma!
I’m using Simulink’s Stateflow as a tool for teaching Faul-Tolerant Systems in the Master of Mechatronics at the University of Málaga.
Using Stateflow for the developmet of Fault Tolerant Systems
One technique for the fault diagnose of systems is based on the modeling of the system as an Finite State Machine (fms), and all the possible trajectories as an special fsm called “diagnoser”. It is based on different methods and used in the classroom as published here.
In this case we are using this tool with surprisingly good results:
It’s not an open source platform, but definitely I’m going to use this tool extensively.
Thanks to my students.

Our animatronic robot made a new appearance after some neck and shoulder surgery.
This was the first Postgraduate Course presentation of the University of Málaga.
We had to refurbish some of the Wall-e’s old joints, but he´s a good nice robot and did his job nicely.
Some work has to be done to improve the robot’s power system and battery charge. Anyone?
Many thanks again to my postgraduate students.

Last December, the 10th (2014), José María presented his Master Thesis about an educational 6 Dof’s manipulator programmable under Simulink.
Educational Manipulator Programmable under Simulink
The arm has been designed to be used on the PIERO platform, and built usin Dynamixel servos controlled by and Arduino Mega.
Good work.
Thaks!
On July, the 15th, 2014, J. Gil Lozano presented its Master Thesis about Educational Mobile Robots programmable under Matlab/Simulink. The original title is “Sistema didáctico para programación de robots móviles en Matlab/Simulink”.
The student participated in the development of the PIERO mobile platform for teaching robotics and mechatronics. He worked with the version 1.0 of the platform and developed lab-work using both the Arduino and the Raspberry PI computing boards.
More details are going to be published at the annual conference of the spanish society of automation.
The report (Project Report) is available, although was written in spanish.
Thanks, Juan!
The student J.C. Camacho presented a work called “3D MODEL DRIVEN DISTANT ASSEMBLY” about remote environment modelling for off-line programming, using computer vision.
He uses structured light and robot parallax to build geometrical models of the objects found. These models are later used to build automatic assembly plans.
Virtual pillars and camera motion are used for model building.
This work was developed at the Wise-ShopFloor research group from the Skövde University, wher he worked with J. Cana Quijada, under the tutoring of Abdullah Mohammed.
A remote programming interface was also developped
The project report (3D model driven distant assembly) was written in english and includes an abstract in spanish.
Last weekend Wall-e showed its last capabilities:
– Head-Arm Gesture control.
– Locomotion control.
– Central controller Wireless communication (raspberry pi based).
– LoL (Lots of LiPo’s)
Esteban and Felix had a very hard work to get all this working together.
People enjoyed watching this expressive character.
Among other things to be done are:
– Minor surgery on its left arm.
– A little brain able to link all its sensors with the locomotion and gesture system.
I’m using this platform as a valuable tool for student Master Thesis. They learn a lot and have a good time. So students are wanted to complete the robot.
… and BTW, If you are in the area and interested on a Show. Let us know!
Cheers
PIERO is a mobile platform for educational purposes. It is modular, layered, open source, arduino controlled and can be programmed under the simulink environment.
If you are interested in the project, visit the PIERO page at: http://gomezdegabriel.com/wordpress/projects/piero-mobile-robot-platform/ and download the latest CAD files in sketchup format.
