3 × Holomonic Wheels 100mm diameter holonomic wheels, capable of two perpendicular direction of travel to 'sit' on the ball.
1 × Bowling Ball A bowling ball for the drive. All the dimensions of the robot will be designed in accordance to this.
3 × Stepper Motor 3 beefiest stepper motors we can find: 125 oz.in (200 steps/rev). We will first try this before switching to geared DC motors, as these don't require feedback
1 × Stepper Controller At the onset, we will use the quadstepper controller from Sparksfun. These are often used in 3D printers as they have four channels. The stepping pulses need to be generated outside the board, but this should'nt be a problem.
1 × IMU The IMU will be used for balancing purposes. Additionally, it will be used for head-locking purpose.
1 × Structure Components The initial design will be based on think acrylic sheets, which can be laser cut easily,
1 × Rplidar Saw this in an electronic store here, think it is a good additional for this project to be used as a SLAM sensor for the robot.
