Building my first robot (III) – Reacting to obstacles
This series reports on the first contact of 3 kids (7, 8 and 11yo) with a Lego Mindstorm robot construction kit in a workshop organized by University of Alcala (Spain) as part of the Alcabot 2011 event. After successfully building the robot, they have to program it using a graphical programming environment. This third video shows how the robot was programmed to measure the distance to obstacles using an infrared sonar and a sensor, thus avoiding obstacles by acting on its wheels.

After successfully building the robot, they have to program it using a graphical programming environment. This is the last video, where the kids finally succeed in programming the robot in a way that is aware of the sumo ring limits and avoids trespassing those limits by using the measures of its built-in light sensor. However, the attempt is not completely succcessful: it works ok when the robot turns on its right, but it doesn’t the other way round. Minor details given the short time devoted to the activity (one hour and a half) so… Well done kids!

Building a sumo robot. A physics question about motors, torque, and gears…?
The objective of the contest is raw pushing power. I have (3) duplicate electric motors at my disposal.
Would I get more power from attaching all three on a single axle that is torqued up with a gear ratio? Or would it be better to have each run independently, with its own gear set?
We are using the lego mindstorms robotics kit, and are limited to those parts, for anyone familiar.
Any other suggestions that may pertain to robot design or further increasing the pushing power are welcome.
Anyone into building robot kits?
Have you ever been able to buy or obtain more detailed instructions?
where can i buy a simple robot building kit for under 40$?
and without it being for11 year olds.
Ive been wanting to build a robot for a long time
and not to easy or hard
