Some days at Solarbotics we like to look at the world upside down. We get on our hands and knees and try to do a headstand and pretend to walk on the ceiling. The sumoshield was created on one of these days.
With this kit you can take an Arduino and place a Sumovore on top of it, this would allow the bot to spin it's wheels aimlessly in the air like a turtle trapped on it's back. Now, turn the world upside down by flipping the Arduino over and allowing the helpless Sumovore be back in the saddle again. Program your Arduino-form-factor-compatible board of choice to control the Sumovore wherever it may roam.
The SumoShield Kit adapts an Arduino, Freeduino, or PICAXE Shield Base to our venerable Sumovore Robot kit. Now you can leverage the power of open source to the world of Mini-sumo! We have provided Arduino Example code that allows the robot to do either mini-sumo or line-following behaviours (under the Resources tab).
Place the Arduino+SumoShield+Sumovore together onto a dark surface or keep in the air to activate Sumo mode after a 5 second delay or you can place it on a high reflective surface (silver or white) to have it enter line-following mode right away after power up or reset.
Just looking for an Arduino Robot kit for general purposes, well this kit is great for that too, you can use the sumovore to avoid obstacles with it's front object detection sensors and it can avoid drops with it's line detection sensors at the bottom of the robot.
Note: For your convenience the SumoShield kit comes with the Male headers press-fit into the PCB, but please be aware that you will still have to solder these pins to make a good connection.
