Is it right for my child?The 4 questions parents ask us about LEGO® Robotics: Challengers.
What is FIRST® LEGO League and does this camp prepare for it?
FIRST® LEGO League is the international robotics competition many schools enter. This camp follows its challenge format — similar missions, similar tables, the same engineering design process — so a child who wants to join a school team arrives already familiar with how it works.
What is SPIKE™ Prime, and how is it different from SPIKE™ Essential?
SPIKE™ Prime is LEGO® Education’s system for older children. The builds are more mechanically demanding, the programming uses text-style blocks with loops, conditionals and variables, and the Expansion Set adds parts for competition-level mechanisms. SPIKE™ Essential, used in our Builders camp, is designed for ages 6–9.
Does my child need to have done robotics before?
No. The camp runs beginner to advanced and instructors assess each child on Monday. Previous robotics or block coding is an advantage, not a requirement — plenty of children start here.
Do children work alone or in teams?
Both, depending on the project. Some builds are individual; mission work and the Friday tournament are usually done in pairs or small teams, because coordinating with a partner is part of what the competition format teaches.
What they'll buildRobots that actually run.

By Friday
By Friday your child will have built a competition robot and run it against their peers.
How the weeks workBuilt to be competition ready.
FIRST® LEGO League is decided on precision — a robot that does exactly what it was told, every run. That is what this camp teaches, in order: control the robot first, then give it senses, then give it judgment, then send it on a mission. Every lesson ends in challenges — your child learns the idea, builds it, then has to make it work. Campers carry on from where they left off and never repeat a lesson they've already done.
- Driving around — drive straight and turn accurately
- Playing with objects — the distance sensor
- Reacting to lines — the color sensor: follow a line, decide on what it sees
- The advanced base — a competition-grade robot from four sections
- My code, our program — coding alongside someone else, navigating by markers
- Time for an upgrade — a dozer blade, a lift arm, crates to move
- Mission ready — everything at once on a full mission course
Most campers cover two or three of these in a week. Where your child gets to is where they start next time.
Not sure which level? Book any week — instructors place your child on Monday morning, and every week continues from there.
There is no ceiling.
Finishing all seven isn't the end of the camp. Instructors hand a camper a build of their own — chosen to what that child is drawn to, and hard enough to take a full week to get working.
eight legs off a single motor, and a tail that strikes
balances on two wheels — knock it over and it stands back up
spins a pen to draw patterns — change the program, change the pattern
And others besides — a ball lifter, an omni-wheel base. Instructors pick something that stretches the child in front of them.
A typical week9:00 AM to 4:00 PM, Monday to Friday.
The shape of a day

A sample week, not a fixed timetable. Instructors set the pace to the group, so your child’s Wednesday may go further than this.
Who's teaching
We hire instructors for the subject they’ll teach: computer science students for our coding camps, engineering and robotics students for robotics, working artists — portfolio reviewed — for art. They come from universities across the country. Every instructor is background-checked and trained by us before camp starts, both on the curriculum and on running a camp day with children. One instructor for every 14 campers.
Supervision
Children are supervised at all times, including outdoor recess in the courtyard or on the lawn. Safety is the first priority of every camp day.
What if my child doesn't like it?
In the first day or two the instructor gets to know how your child is finding the camp. If it isn’t the right fit, we’ll suggest a switch — a different subject, or a camp better matched to their level. If your child simply isn’t enjoying it, we’ll refund the weeks they don’t attend, prorated. Email us and we’ll sort it out.
From parents
After the Friday showcase.
“We had a wonderful experience with the STEM4Kids summer camp! My child learned so much and really enjoyed the hands-on activities and learning opportunities. It was amazing to see how engaged and excited my child was throughout the camp. Shwetha was extremely responsive, quick to reply, and very approachable and reliable. Any questions or concerns were answered promptly, which made the whole experience very smooth and reassuring. Highly recommend STEM4Kids for parents looking for a fun, educational, and engaging summer camp for their kids”
Grishma Padhiar
“My 6 years old son enjoys this camp so much! The instructors partner him up with two 7 years old kids and he had a blast working with them. The main instructor is so kind to him. Overall a good balance between playing and learning environment here.”
Chia Hui lee
“Fue un espacio de diversión y aprendizaje muy agradable para mi hijo, aprendió y practicó durante su summer camp, las actividades entretenidas y de gran interés para él. Su instructora: Shweta, muy amable, siempre nos comentaba sobre el avance de mi hijo y además nos mostraba videos de sus actividades, así como también permitieron que el nos mostrara lo que hacía durante el día. Su último día tuvieron una actividad lúdica de ver una película y compartir con sus amigos. El año entrante regresaremos por mas tiempo. Recomendado. It was a very enjoyable space for my son to have fun and learn; he learned and practiced a lot during the summer camp, and the activities were entertaining and highly engaging for him. His instructor, Shweta, was very kind; she kept us updated on his progress and showed us videos of the activities, and we were also able to see what he had been doing during the day. On his last day, they had a fun activity where they watched a movie and socialized with friends. We will be back next year for a longer period. Highly recommended.”
Maria Barbosa
“Our son had a wonderful time at camp! He looked forward to going each day and was excited to share all about what he’d worked on with us at home. Communication with parents was also great and very much appreciated! So nice to be able to send him off each day knowing that he was in great hands and having a fun time!”
Amanda Lavrich
“This review is pending since last summer. My 9 year old son attended robotics summer camps here for several weeks. The camps were quite engaging and my kid spent his time productively here. Shweta hires young talent to teach kids. This brings in the latest knowledge, enthusiasm and energy to the class. Additionally, the camp provides a very safe space for kids. She is vigilant towards the classroom dynamics and makes the needful changes. We are returning back this summer for another round!”
Juhee Rp
“Our son he really enjoyed it, he came home happy each day and said he got to do things that he really enjoyed and mentioned the teachers are awesome ”

“My son absolutely loves the camp. The teachers there took good care of him and also taught him good technique to do the painting. He brought home a nice painting hanging on the walls of his room now.”
Alex Fit-Florea
“For Lego robotics enthusiast this is a great camp. We really like the choice of location because kids get to go out during breaks! The camp itself is very impactful for students who have already done We Do Lego robotics and know some coding. Teachers are computer science undergrads which is a big plus !! And the owner herself is very flexible and always ready to answer questions and explain!!!”
Kavita Sharma

Mijeong Jeon
“I had initially enrolled my old son at stem4kids summer camp last summer in math and english program. I was very happy with the kind of overall enrichment they provide to the kids. By end of summer i ended up enrolling in their after school program and i could not be happier. They work on overall development of the kid including robotics, math, english, spanish, public speaking and so on. I highly recommend their program.”
Vijaya Prabhakara

Chandra Rentachintala
“Very nice afterschool with caring teachers. I am glad we switched our daughter from champions here, she is thoroughly enjoying here.”
Chandra Rentachintala
“My both sons attended STEM4Kids this summer. I am very happy with the progress of my elder son where STEM4Kids has created a foundation / interest in Java programming. My son also attended Python summer classes last year. My younger son attended SCRATCH programming this summer and he loved it. Overall STEM4Kids was very helpful and provides a good platform for kids to create a foundation and interest in STEM.”
Sanjeev P
