Tomas, our tutor, and classmates came with us and played with the robotic arm after we finalized the hardware of robotic arm and were doing the final testing of software.

In the third laser cutting, we produced one more component to fixed the robotic arm on the wood base. Then we played the robotic arm for testing the whole set-up. Isaac picked some woods from recyclable collection points in Chai Wan, Hong Kong to create a base for robotic arm. After the wood work, he colored the wood base to black with spray paint. Leoson was testing the leap motion quickly while he finished the simple mapping in the computer. Here is the video of this test. Leason set the basic mapping in his computer and was testing the X-Y-Z direction of the robotic arm. We did a simple circuit for the robotic arm. Then Leoson and Hugo started to calculate the moving angle and the mapping of the arm in Processing an d Arduino program.Leoson was testing the robotic arm once we grouped all components of robotic arm together. There were the wrong acrylate components we made in last two laser cutting. Some of the components cannot be putted on the arm, some of the holes we designed were too small. Also, because we over turned the servos manually, we crashed three servos in this way...... R.I.P. This was the second try of laser cutting after we modified the plan of robotic arm. The video was a short video recording of real time laser cutting for anyone who was interested to see about laser cutter. By the way, it was very smelly while the cutter was running even exhaust fans was turning-on together. The mist was toxic mostly since it was the sublimate of materials. After the first try of laser cutting, we were testing the acrylate components and modifying the set-up of the robotic arm. |
