Boe-Bot interaction

Klap

As part of a class project my teem had to use two Boe-Bots. Boe-Bot 1 grabs a Lego off of a rotating platform, goes to an exchange zone to hand off the lego to Boe-Bot 2, Boe-Bot 2 takes the lego and transports it to an exchange zone where it supposed to stack it on top of other Legos. My teem was able to accomplish most of these goles but the exchange seems to be a little off. I have posted a video of this presentation on my class webpage, so if some one could view it and tell me a way to improve the Lego exchange I would appreciate that.

I have also included much more information about this project on the webpage listed above including: Picutes of robots (three primary views and an isometric view), a project report, circuit diagrams for all four Boards of Education used, Programming flowcharts, PBasic code used, project scheduals, a PowerPoint presentation, and two project videos.



Please also let me know what you think about the webpage.

Color makes a site 1000x better...

Anyway, your transfer might be better if you could make the lower gripper into a V shape. Then the block drops into the V and stays, and you can rotate the grips to a vertical position. Or, as an alternative, you could put a bottom on the gripper so that the block cannot fall out.

It might be helpful if you could get the exchange from ground level (the black mat makes it very difficult to distinguish details), and edit the clips to be exclusively gripper.

Thanks for the ideas. We tried using a gripper with a bottom but then the Lego wouldn't stack easily at its destination. Our group never thought of a V shape gripper. The only problem I can see with this is that our bots are already very heavey and adding another servo may make it close to ten pounds in weight. Do you have an idea about how could we alter the design to allow rotation without adding weight?

Ten pounds is way too heavy for the Boe Bot. You'll probably burn out your servos that the whole thing rides on. However, if it doesn't, more power to you. Anyway, my recomendation is to take some time to learn how to do some basic machining, then redesign everything with aluminum. However, if this is not an option, don't worry. Might I ask what the weight limitation is for? If it's for saving the servos, then I have a solution: add a fourth wheel as a caster, and spring load it. This will take up some of the weight, and still allow the bot to have full mobility.

As for the staking of the bricks: how are you stacking it? Are you fastening the blocks together in the lego fashion, are you building a loose stack, or are you just dumping the brick on top of everything else?
