From the product description
Tribot is one of the latest in the line of personal robots from WowWee. This innovative talking companion is more than just your average robot -- Tribot is fresh off the robot assembly line and is ready to interact with you whether it is playing with his built-in games or telling you jokes. Remember though, he's only a young robot so he will need help from you to give him commands using the remote controller. Requires eight "AA" and three "AAA" batteries, not included. Measures 9"L x 8.5"W x 15"H.
