The Robot with X-Ray Vision
MIT researchers have created a robot arm called RFusion that can find hidden objects. It uses a special antenna to send out radio waves that can travel through cardboard boxes or piles of clothes to find tiny tags attached to things like keys or wallets. Once the robot knows where the tag is, it uses its camera to reach in and grab it. This robot is so smart that it can find hidden items 96 percent of the time! Learn more!
Wee Ones
The robot sorts its finds into two groups. It puts 6 hard items like keys in one pile and 4 soft items like socks in another. Which pile has more items?
Little Kids
The robot follows a code with three steps: 1. Scan, 2. Lift, 3. Drop. If the robot follows the code 3 times, how many times will it lift an item?
Big Kids
The robot's code says: IF the item is heavy, THEN use two hands. ELSE use one hand. If the robot finds 4 heavy keys and 5 light socks, how many times will it use one hand?
The Sky's the Limit
A scientist writes a program to help the robot find tags (T). The time it takes is 10 seconds, plus 5 seconds for every tag it finds: 10 + 5 * T. If the robot finds 8 tags, how many seconds does the program run?
