1. [VARIABLES] - use variables for the main values so that you'll be able to reuse them and give them descriptive names.
2. [CODE STYLE] - use correct check for property presence in object. Some properties can be present, but still contain falsy value.

GOOD EXAMPLE:

if (key in robot) {

EVEN BETTER EXAMPLE:

if (robot.hasOwnProperty(key)) {

BAD EXAMPLE:

if (robot[key] === undefined) {

if (robot[key]) {

3. [NAMING] - use proper names for variables - if you want to name variable result, pick a better one :)

4. [CODE STYLE] - You should return the value immediately in if statements. And don't use else after return statement. If return is performed - code after it won't be executed anyway.

BAD EXAMPLE:

if (condition) {
  return x;
} else {
  return y;
}

GOOD EXAMPLE:

if (condition) {
  return x;
}
return y;
