Bad argument #1 string expected

Hi!(again)

My program for robot(flashed in eeprom) dont work and causes error i typed in topic title.

Here is the code:

robot = component.proxy(component.list("robot")())
rs = component.proxy(component.list("redstone")())
function getBatteryPercent ()
  local percent = computer.energy() * 100 / computer.maxEnergy()
  return percent
end
function wait(seconds)
  local begin = os.time()
  repeat
    computer.pullSignal(0.05)
  until os.time() - begin >= seconds
end
while true do
  robot.turn(true)
  robot.turn(true)
  robot.move(1)
  while robot.compare() ~= true do
    robot.move(3)
    if robot.detect(5) == true then
      robot.turn(false)
      robot.swing()
      robot.turn(true)
    end
    if robot.detect(4) == true then
      robot.turn(true)
      robot.swing()
      robot.turn(false)
    end
  end
  robot.turn(true)
  robot.move(0)
  robot.turn(true)
  while true do
  if redstone.getInput(1) > 0 then
    if getBatteryPercent() < 20.0 then
      rs.setOutput(0, 15)
    else
      rs.setOutput(0, 0)
    end
    wait(60)
  else
    robot.move(3)
end end end

You forgot to specify the direction in a functions swing() and compare()

Ðnd the robot can not move to the sides 4 and 5, for this it is necessary to turn to left/right.

What do you mean about sides 4 and 5? There is no code thats moves it to this sides.

Only this way:

robot = component.proxy(component.list("robot")())
