Specs
rev 1
Category | Details | Notes |
---|---|---|
Remote | Microphone | For imput of commands. |
Battery | Probably AA (rechargable) | |
Buttons | For clearing all. Selecting certain areas of the board. Saving all data on the board. And push to talk. | |
Robot | Magnets | To keep the robot attatched to the board. Not to tight so it is hard to move but should never fall off. |
Computer | To manage position, commands, drawing, calibration etc. | |
Connection | With the remote, probably Wifi or Bluetooth depending on the battery lifetime. | |
Wheels/Continuous track | Depending on what works the fastest and makes less noise. Should also not interfere with the already written text. | |
Battery | Should cover about 8 hours. | |
Markers and wiper | Since printing on the board is not an option we need a various selection markers and a wiper. |
Category | Part | Elaboration |
---|---|---|
Markers | Black whiteboard marker | Easy restockable markers for whiteboards. |
Red whiteboard marker | The markers are installed on the side of the robot so it can be read faster. The ones not in use are not against the board and capped. | |
Blue whiteboard marker | ||
White chalk marker | Chalk markers for blackboards. These should be able to spin to make dots. | |
Wiper | Board wiper | Also place on a side and can just like the markers be lifted from the board when not needed. |
Whiteboard cleaner | Could be added to help clean the board better. | |
Computer | Speech to text | To translate the users sentences into text and to receive commands for actions. |
Software | Plot , draw amd callibrate equations, diagrams, graphs and other mathmetical functions. | |
Memory | Store previous work for fast repetitive access. | |
Wheels/Continuous track | Should be tested to see what works best regarding; speed, noise, interference with board, packaging for travel, weight. |
rev 2
rev 2 of the specifications of the robot.
Category | Part | Elaboration |
---|---|---|
Robot | Size | 24x24x8 cm (LxWxH) |
Handle | 2 handles with a height of 3 cm and a bar at one side to recognise the top position. | |
Magents | A multiple of 4, Neodymium magnets, placed along the sides. Size and amount depending on force needed. | |
Wheels | 2 sets of 2 omni wheels. Every set placed diagonally across and every set 90 degrees turned. | |
This way, a set of 2 wheels diagonally oposite will be used to drive in a single direction and the other set is used to drive in the other direction. | ||
Motors | Each wheel is connected to a stepper motor to precisely move the cart around and keep track of the position. | |
Writer | A stepper motor is used to precisesly drive a screwthreaded axle that moves the penholder in 1 dimensional direction. | |
2 extra axles are used to guide the penholder block. | ||
Pen holder | Holder is slightly tilted and has multiple holder shafts for markers. The holder can be rotated to select another marker. | |
A servo in the block is used to rotate the markers. |
