LEGO mobile arm ''Jey-Jey''
Jey-jey was my V1 successful huge LEGO robotic arm, completed in 2010. It weighs 4 kg without load. The full glass of water in the video weighs 600 g. This lego robotic arm has 1 lego NXT, 1 Lego RCX brain, 5 functions (2 DOF). It has also a strong pneumatic gripper. All functions are controlled by NXT and RCX program and it's not RC. It has 4000 Lego bricks. In 2008, I tried to bring to life this mobile arm, but was impossible due to the weak RCX motors having little torque. By using xl pf motors the arm was finally able to move without problems.
For myself, this project remains a Lego breakthrough.

LEGO mobile arm "Vasilis''
This is a second version of LEGO mobile robotic arm which is 3 times faster than Jey-jey. The Arm finds its destination without black line tracking. It has 1 EV3 Brick giving 4 functions (2 DOF) using 2 EV3, 1 NXT and 1 EV3 Medium motor. It is both RC and programmable (using IR Sensor).
The arm is programmed with EV3-G. Was built in 2016 and has 3000 Lego bricks.

LEGO Robot "Nemesis"
Nemesis is the most complicated LEGO robot ever built by myself in 2016.
It uses air pressure to control 22 air functions (19 DOF), all controlled manually by 22 air switches. Also, it has 2 mechanical RC functions to move the whole robot forward and backwards. Uses totally 3 XL PF motors. One XL motor is used as an electric air compressor.
An 8kg machine of totally 8000 lego bricks couldn't get unnoticed.
