The amazing work of Francisco García was bringing to life one of the old electrical tricycle used for people transportation inside the
Expo’92 in Seville, last century.
His work was to design and implement an steering control system. We used new lead batteries (12 + 12V) and added a servomotor with direct coupling to the steering axe.
The controller has been implemented with an Arduno Mega and the PID control has been tuned and programmed in simulink.
For testing purposes, an open loop throttle control system has been added, making it easy to remote drive the vehicle using a PS2 wireless joypad.
It was bot hard and fun.
Last July, the 9th, Ernesto Guerrero presented his Master Thesis Based on the development of a 3D printer for nano-hybrid resin printing.
He took the
Lisa Simpsons design as a starting point and implemented an innovative bowden-like hydraulic extrusion system. There is still some work to be done before this device may be used for medical and dental applications but he got very promising results.
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.
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!
