Last friday we received the LEGO kits!! We are really excited to take a look at them and start building the challenge elements as soon as possible.

After an initial check of the kits and building an appropriate table to place the game, we started building the challenge and today we have it almost ready.

We look forward to build our prototype robot to see how it behaves on the track. We know that the navigation will be a big challenge, so we rely on the sensory capabilities of the robot to determine at any time where it is located to be able to make adjustments to the route to achieve the objectives.

This is all for today, keep in touch.

We’ll be back soon!

This weekend we got together to celebrate having been finalists in the first stage of the project. We are proud to have done a good job and we are very excited about the second phase.

We started working on the CAD design of the robot. We began reviewing solutions to the design challenges we had anticipated during the development of the design proposal presented in the first phase. We started with a first draft of the Rocker-Bogie suspension system. The objectives were to be resistant, yet simple. We dealt with the difficulty of size constraints and the transmission system to be able to provide motive power to all six wheels.

We also address how to make the robot do accurate turns and the choices we have so far are

1. Turn the four corner wheels inside and make the robot turns on his central axis
2. Use non turning wheels and use a compass sensor to increase precision

The final choice will be defined after the initial tests of the prototypes. Below are the models we’ve done so far, along with the files in Lego Digital Designer. Please feel free to make comments and share your ideas.

We’ll be back soon!
